Can of compressed air for blowing out a laptop. We make a can of compressed air Refillable can of compressed air

Few users realize how important it is to have compressed air in canisters for a computer.

But in fact, it can save you from unexpected breakdowns, discomfort in using the device, as well as from a number of other unpleasant situations.

Where to get quality compressed air

Alas, it is. The prophets were right, and now even air is for sale.

Canned compressed air for sale different types and choosing it in the distribution network, it is important to understand that you are buying compressed air in cans for a computer, and not for any other device.

So it's worth it search in computer stores in the departments of consumables and means for the care of computer equipment. Similar products can also be found on similar websites. If you try to find something similar in other places, certain problems will surely be associated with this.

This is because if compressed air is used for other purposes, it may contain third-party components, the presence of which can be very dangerous for the contents of your case, or a similar device that requires cleaning.

For example, manufacturers of compressed air for car repairs can add agents to prevent further deterioration of car parts.

But the compressed air used by jewelers may contain components that, in the process of work, will allow to bind microparticles. precious metals, since they can be reused in the creation of other products.

Advice: pay attention to where you buy compressed air and the contents of the bottle. You can get it from the inscription on the label. For example, an unscrupulous seller can “pump” air that is not suitable for processing computer parts.

How to use compressed air

Usually compressed air sold in a metal container– bottles where air is preserved under pressure.

The capacity of these containers may vary depending on the preference of the manufacturer, but usually large volume cylinders are not commercially available due to the safety requirements of the product being sold.

Note, that in order to use the compressed air from the bottle, the whole set must be used.

Yes exactly.

Compressed air is sold not just in cans, but in the form of a kit, which also includes a special nozzle in the form of a thin polymer tube.

With one end in the form of an adapter, it is put directly on the movable nozzle of the cylinder, and the other end is directed directly to the surface to be cleaned or the element placed on it.

Contrary to popular belief, mindlessly pressing the spray valve is not worth it. It is necessary to adhere to several strict rules that will save you from problems in the future.

Here are a few of them:

• the air jet must be directed directly to the object to be cleaned;
• do not release all the compressed gas in one spray;
• pressing should be serial and short-term.

All these rules are strictly justified.

For example, short-term directed pressures contribute to economical use air, because its pressure is quite enough to remove dust, and to remove a number of sticky contaminants.

How to replace compressed air

As noted above, replacing one gas cartridge with another can lead to irreparable consequences.

For example, flammable gas mixtures used for cleaning can cause a fire, short circuit, or poor cleaning performance. Similar situations may occur if humid air or flammable gas is present in the vial.

At the same time, the consequences of cleaning with such a gas may not even appear during its execution, but after, when the computer or other electronic device being cleaned is connected to the network.

When choosing a replacement for refrigerant cartridges (this is what manufacturers most often use), it is worthwhile to clearly understand the features of the use of compressed gas and the purpose of its use. Accordingly, the gas directed to the housing must be dry, without additional impurities and preferably inert. Unfortunately, at home, it is not always possible to comply with such requirements and it is necessary to use not compressed gas, but something else.

Alternatives at home

The two most common ways to solve this problem involve the use of household appliances.

In the first case, this hair dryer, which is far from every computer owner, but in the second - vacuum cleaner. But in this case, not everything is so smooth.

As for the hair dryer, when using it, it is important that it works in the mode without heating the air. Otherwise, you can pay with the performance of the computer, since in many of them, for example, in laptops, glue can be used, which, under the influence high temperature melts.

As for the vacuum cleaner, when using it, it is important to use reverse mode when air is not sucked in, but, on the contrary, blown out. This is necessary in order not to inadvertently pull out the soldered wire from the case, or when high power vacuum cleaner any other component.

This feature is not provided in every model, so be careful.

The right way to use compressed air

How to make a spray can with your own hands

As for consumable disposable, the cost of an air canister seems simply sky-high.

And although it is associated with a complex technological process production, many consider it unreasonable. That is why some users are trying to make a similar tool for at home.

This task is quite feasible, but it will not be possible for everyone. This is because for its implementation it is necessary to provide several details at once.

First, an empty container will be needed.

You can use, for example, an already used container from compressed air, but in no case from varnish or deodorant, since they may contain residues of alcohol or chemicals.

The second required component is Automobile compressor . It is he who will allow you to pump air into an empty bottle.

And, of course, the connecting elements - a car camera nipple and a fragment gas burner, which will allow you to connect the cylinder with the compressor and reduce air loss during refueling.

Important: with this method of refueling, it is important to be especially careful. Firstly, such a mixture cannot be used on all surfaces, since it contains flammable oxygen, and secondly, when refueling, the permissible pressure in the bottle must not be exceeded. Otherwise, it will break and cause injury or other damage.

How to make a homemade reusable compressed air tank for cleaning a computer?

This method eliminates the violation of the structural integrity of the cylinder by screwing, gluing or soldering bicycle, motorcycle or car nipples. This allows you to bring the pressure in the cylinder provided by the manufacturer and eliminates the shooting of the above objects at the user. The role of the fuse when the permissible pressure is exceeded is played by a rubber tube with a clamp (do not tighten the clamp too much).

Precautionary measures

In order not to harm either yourself or the device being cleaned, you should pay special attention to a few more rules.

For the user, even when working with safe compressed gas, difficulties can also arise. They happen if the owner of the gadget is prone to allergies to dust or asthma.

Allergic reactions are inevitable during processing of the computer, since the air blown out of the case in a concentrated form contains dust. To prevent it from getting on the skin, eyes or respiratory tract, it is necessary to use personal protective equipment:

• glasses;
• respirators;
• gloves.

It is inconvenient to work in them, but this is a necessary security measure. Also, do not use compressed air for other purposes and direct it, for example, to mucous membranes.

As for the device to be cleaned, it must be turned off before processing.

Moreover, it is necessary to wait until it cools down and only after that proceed to the next stage. In the event that the body is collapsible, it is necessary to dismantle the covers or removable walls to provide comfortable access and unhindered dust extraction.

Cleaning of computer cases starts with moving parts, for example, then moves on to multiple radiator grilles (parallel metal plates) and only after that does cleaning of printed circuit boards begin.

It is important not to scratch their surface and to do this, keep the adapter tube at a small distance from the board.

Conclusions and parting words

As you can see, compressed air in canisters for a computer is very useful thing, while, despite the external simplicity, it has many features of application.

Removing dust with it allows you to reduce the likelihood of a laptop, and also removes a sudden rumble coming from the case.

It is important that the chances of damage to the case and its contents, provided that a properly selected cartridge is used, are minimal.

This is because cleaning in this way is carried out contactlessly and the likelihood of mechanically hooking any even easily accessible elements is minimized. And hard-to-reach places, on the contrary, are cleaned with a high degree of efficiency due to the fact that the adapter tube is much thinner than the same hair dryer or vacuum cleaner tube.

Despite the fact that compressed air in canisters for a computer is consumed in just one use, it should not be stored in improper conditions.

The vial should be protected from direct sun rays, and also not to give to children for their safety, because the pressure in the can is much higher than atmospheric pressure.

There are such life situations when it is necessary to clean the computer from dust or other household appliances where it is difficult to crawl with a pipe from a vacuum cleaner. Perfect option to solve such a difficult task is to buy a compressed air cylinder in a store. But why buy, spend money when you can do it yourself from improvised means.

How to make a compressed air tank

Let's cook necessary materials:

• Aerosol can (aluminum or tin);
• Adapter for car pump;
• Nipple (fitting) from a bicycle;
• Poxipol or epoxy glue;
• Thin wire;
• The tube is hollow, such as can be found at McDonald's;
• Pliers, drill, pump, file.

We take out the nipple (fitting) from the bicycle tire and grind the mounting grooves with a file. We do this carefully so as not to damage the thread. The nipple must be round.

We take an empty aerosol can, for example, from under the air and on the bottom in the center we drill a hole of the same diameter as the adapter.

When the hole is ready, screw the adapter. It will be tight to screw in, as it should be, for help, take pliers and screw in, threading. As a result, the adapter should be easily screwed in and out of the hole.

Now you need to tightly fasten the adapter with the nipple. Take poxypol or epoxy glue and put it on the nipple and insert it into the adapter. Then we grease the hole at the bottom of the cylinder with glue and screw the adapter with the nipple all the way. We leave the balloon for a day to dry the glue.

When the tube is pulled out, we drill a small hole in the spray bottle under the hollow tube. To keep the tube tight, glue the end of the tube.

We are waiting for all the glue to dry and our compressed air cylinder ready.

Such a cylinder is able to withstand 40 atm. Pumping it up hand pump for bicycle. We pump up about 4-5 atmospheres. This pressure is enough to clean the keyboard from crumbs and even system unit computer.

Usually, we are not enthusiastic about a request to clean a computer or other household appliances from dust, which is full of hard-to-reach places. A can of compressed air works well for this task, but it is not sold on every street corner. So it's better to make it yourself.

We prepare the necessary materials and tools:

- tin or aluminum aerosol can;
- nipple from the bicycle chamber;
- adapter for a car pump;
- an empty tube from a ballpoint pen paste;
- epoxy glue (poxipol is best);
- thin wire;
- drill, pliers, file, pump.

We construct

We take out the nipple from the old bicycle chamber and grind off the flanges (installation grooves) with a file - carefully so that the thread for screwing remains intact. We need a perfectly round nipple.

We take an aerosol can (from shaving foam, hairspray, deodorants, etc.) and drill a hole in the center of its bottom along the diameter of the adapter. You can see the adapter on the lower right photo (golden cylinder to the right of the cylinder).

We bend thin wire in the form of a hook and with its help we pull out plastic straw located inside the can - we do not need it.

The adapter will fit tightly into the hole prepared for it. Using this, with the help of pliers, carefully screw the adapter into the hole, creating a thread. The adapter should easily screw into and out of the hole. While we unscrew it and set it aside.

Now let's prepare the glue. Poxipol components - glue and activator - are contained in separate tubes. We squeeze them onto the plate in a ratio of 1: 1 and mix with each other with a stick (the plate and the stick are included). Lubricate the nipple with glue and insert it into the adapter.

Having smeared the hole at the bottom of the cylinder with glue, we screw the adapter with the nipple into it.

We screw it all the way. Now a few hours (about a day) the glue should dry.

When the glue dries, we drill a hole in the spray bottle under the tube from the paste. The tube must be clean: wash it with acetone or some solvent. So that it fits snugly into the hole and holds well, we lubricate the end of the tube with glue.

Again, we wait until the glue dries, and here it is, a can of compressed air, ready:

Intended use of the can

We inflate the balloon with a bicycle pump. Manually, you can download 4-5 atmospheres. A foot car pump can pump up to 10 atm. The electric compressor will pump up to 20 atm. The aerosol can is designed for approximately 40 atm.

I have two of my favorite tools, with the help of which 85% of any equipment malfunctions are repaired. It's WD-40 and compressed air. For repairs, it is enough to blow and lubricate.

As usual, the air ran out suddenly. And on every corner this thing is not for sale. I had to zabatsat such a design.

Source materials:

• Empty aerosol can.
• Bicycle nipple with an adapter for a car pump.
• Tube from WD-40 or stripped PVC wire insulation.
• Epoxy. Poxipol is perfect.

Some time later, when the material of the article was already ready, I made the same thing from an empty standard 400 ml compressed air cylinder. He worked much better.

At the nipple we grind the edges.

In the bottom of the cylinder we make a hole 8mm. Through this hole we take out a plastic tube. We won't need it. We cut the thread in the hole with an adapter for a car pump.

With a 2mm drill we expand the nozzle under the tube.

The tube should fit snugly into the hole and hold well.

We screw the bicycle nipple with epoxy into the adapter. And the resulting part is also screwed with epoxy into the bottom of the cylinder.

Something like this should work.

We inflate the balloon. We pump with a bicycle pump while we have strength. You don't have to worry about integrity. You can manually pump up 4-5 atm; foot automobile 5-10 atm; electric compressors give up to 20 atm. The balloon itself is designed for 30-40 or more atmospheres.

It is believed that a can of compressed air can be useful for removing dust from hard-to-reach places in computers, laptops and other electronic equipment.

I have been dealing with personal computers for 33 years and have never used a compressed air canister - I admit my denseness and backwardness from modern progressive trends in electronics repair, but my experience shows that you can do without them, although it is necessary to try out a compressed air canister necessary.

In Yandex.Market I found FIS F1-1007S — Canister with compressed air, 283 gr. (236 ml). Price: 780.84 rubles and delivery 600 rubles.

In the YULMART store (Snezhnaya St., 26) you can buy Pneumatic cleaner Cactus CSP-Air400 for cleaning equipment, 400 ml at a price of 400 rubles.

Cactus CSP-Air400 is a pneumatic cleaner for professional cleaning of hard-to-reach places in equipment.

Purifier high pressure allows you to clean hard-to-reach places of printers from dust and dirt, computer keyboard, copiers, fax machines and various office equipment. Powerful jet pressure ensures quick and efficient use.

Once in the area, I will purchase a can of compressed air for testing. Cactus CSP-Air400- 400 rubles are equivalent to about one full-fledged Soviet ruble, that is, about a third of a bottle of Vodka drunk for three. So I don’t drink Vodka for a long time, I can afford to buy such a Canister with compressed air.

Pros - Relatively inexpensive big size(400 ml), straw for spot use included
Disadvantages - none
General impressions - Price / quality at altitude

User Experience: Recently May 11, 2016
Advantages - An indispensable tool for cleaning PCs and other electronics.
Disadvantages - A small life hack for those who have weak wind: this is due to the cooling of the cylinder during the purge process. When the bottle is cool, just warm it under the stream hot water- it will blow in such a way that it will not seem small (until the balloon cools again). Repeat until the desired result is achieved, or until the contents of the can are used up.
General impressions - great thing at reasonable price. Anyway, cheaper than retail in the store.

Cheba
User Experience: Recently March 12, 2016
Advantages - none.
Disadvantages - Absolutely useless in cleaning the PC. The air flow is so weak that it can barely blow off the dust.
General impressions - 400 r down the drain, it's easier to take a PC, go to a nearby car service and blow it out of the compressor for this money!

I have a car compressor with which I pump up the wheels of my cars - I can bring it to the apartment and power it from the Volvo 744 battery stored in the apartment.

This solution has a drawback. As the pressure drops, this thing blows worse. Therefore, it is advisable to take large volume cylinders. For example, from air fresheners.

It is worth noting that in the same way you can make a reusable WD-shku, only in the lower part you need to solder (weld, glue) the nut right size and screw the nipple no longer into the body, but into the nut. Pour purified kerosene through the funnel (and in the WDshka it consists of it), screw in the nipple, pump it up. Given that 400 ml. WD costs 250 r, and a liter of kerosene 50 r, then this device is worth thinking about :-)

#zabatsay 16.04.2011 21:11
Good idea! Only the composition of WD-40, if I'm not mistaken, is white spirit, oil, tricky additives. However, I'm not sure that this thing will work well with compressed air. We need carbon dioxide. Need to try.

# dobryni 16.04.2011 13:00
By the way, WD is not a lubricant at all, it is a cleaner and it cleans not only rust and dirt, but also the remnants of the lubricant of the mechanism itself. So after cleaning, do not forget about the usual lubrication :-)

# dobryni 17.04.2011 02:53
It is checked up, clears not worse. 2 flaws, does not leave behind protective film(those additives) and stinks terribly, but everything has its pros and cons
:-)

# DeOS 04/30/2011 21:42
I have never seen such an adapter, or maybe I didn’t pay attention, but the idea is interesting. By the way, did the smell of dezica remain?

# Dimka45kgn 16.06.2011 12:58
When I did it, I did it according to your instructions - I thought that I would not be able to pull the tube out of the cylinder, but it turned out to be so simple, thank you!

# Vladickbeliy 28.01.2012 20:38
I also made such a thing from a freshener

# priborr 24.04.2012 13:30
and who made such a thing, tell me: should it be an aluminum cylinder or is it suitable from tin?

# kelendria 10.08.2012 23:01
better take a siphon. it is also made of aluminum. and drilling is not necessary if there is no siphon. Homemade balloon with compressed air

# igor 06/05/2012 15:42
What pressure can be given to a 75 ml can?

# Trumkin 06/15/2012 18:14
and immediately an automobile nipple without an adapter cannot be installed?

# kelendria 10.08.2012 22:53
balloon is bullshit. I made it easier. I took an old siphon, screwed a nipple into a plastic cover. no drilling or gluing required. and blew the compressor. turned out to be awesome stuff. you can buy an old siphon at a flea market or ask a neighbor - such garbage in the mezzanines in bulk

# gra 26.01.2013 21:52
I have a question: will a 150-200 mm balloon withstand an atmosphere of 5-7? and it's kind of creepy.

#zabatsay 27.01.2013 04:54
Must endure. Such cylinders are designed for 30-40 atm.

# Gauss 14.02.2013 19:27
Good afternoon! I made 250 ml from a can, pumped up to 4 atmospheres, the pumped air is blown out in just 5 seconds. How many atmospheres do you need to pump up to last longer? Who worked with what volumes and pressures, how much pumped air was enough?

# Leader 03.03.2013 13:50
I tried to do it as written, took a Defender 280 ml bottle and pumped it up to 8 atm using an autopump, the bottom of the bottle squeezed out more and the nipple flew off. I screwed the nipple back with glue and the next day it swung again but already 5 atm., The air was blown out in 4 seconds. Then it is not clear what kind of air is used in this cylinder and what pressure is there, that it cannot even withstand 8 atm.

#zabatsay 03/03/2013 15:19
280 ml is not enough for compressed air. In such cylinders, either freon or liquefied natural gas. In fact, it is like any aerosol can, only without the filler. take from deodorant - preferably the more the better. more air. and you need to glue the nut, and then screw the nipple. after gluing, seal everything with sealant to a flat bottom. so reliable and will not hang out. also glue the tube from the Chupa Chups - it is more reliable.

I came to the conclusion that it is most reasonable to use Siphon and cans of carbon dioxide, and I consider it irrational to pump air into aerosol cans.

I invite everyone to speak in
