Do-it-yourself compressed air in cans. A can of compressed air for blowing out a laptop. How to make a spray can with your own hands

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

I've been dealing with this for 33 years personal computers and I have never used a can of compressed air - I admit that I am dense and lagging behind modern progressive trends in electronics repair, but my experience shows that you can do without them, although trying out a can of compressed air is definitely necessary.

In Yandex.Market I found FIS F1-1007S - Compressed air can, 283 g. (236 ml). Price: 780.84 rubles and delivery 600 rubles.

In the YULMART store (Snezhnaya str., 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 areas of equipment.

Cleaner high pressure allows you to clean hard-to-reach places of printers, computer keyboards, copy machines, fax machines and various office equipment from dust and dirt. The powerful jet pressure ensures quick and efficient use.

Once in that area, I’ll buy a can of compressed air to try Cactus CSP-Air400- 400 rubles are equivalent to approximately one full Soviet ruble, that is, about a third of a bottle of Vodka drunk by three people. So I haven’t drunk Vodka for a long time, I can afford to buy such a can of compressed air.

Here are three reviews:

Usage experience: Recently February 18, 2016
Advantages - It is relatively inexpensive, big size(400 ml), tube for spot use included
Disadvantages - None
General impressions - Price/quality is excellent

Usage 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 happens due to the cooling of the cylinder during the blowing process. When the bottle has cooled down, simply warm it under the stream hot water— it will blow so much that it doesn’t seem like enough (until the balloon cools down again). Repeat until the desired result is achieved, or until the contents of the bottle run out.
General impressions - Excellent item at a reasonable price. In any case, cheaper than retail in a store.

Cheba
Usage experience: Recently March 12, 2016
Advantages - none.
Disadvantages - Absolutely useless in cleaning PCs. The air flow is so weak that it can barely blow away the dust.
General impressions - 400 rubles down the drain, it’s easier to take a PC, go to a nearby car service center and blow it out of a compressor for that money!

I have a car compressor that I use to inflate the wheels of my cars - I can easily bring it into the apartment and power it from the Volvo 744 battery stored in the apartment.

I have two of my favorite tools, with the help of which 85% of any equipment malfunctions are repaired. This is WD-40 and compressed air. To fix it, just blow it out and lubricate it. As usually happens, the air ran out suddenly. But this thing is not sold on every corner. I had to play with this design.

Source materials:
Empty aerosol can.
Bicycle nipple with adapter for car pump.
A tube of WD-40 or stripped PVC wire insulation.
Epoxy. Poxypol is perfect.

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

We grind off the edges of the nipple.

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

Drill 2 mm. expand the nozzle under the tube.

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

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

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

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

It is worth noting that in the same way you can make a reusable WD-shk, only in the lower part you need to solder (weld, glue) a nut the right size and screw the nipple not into the body, but into the nut. We pour purified kerosene through a funnel (and that’s exactly what the WD tank consists of), screw in the nipple, and pump it up. Considering that 400 ml. WD costs 250 rubles, and a liter of kerosene costs 50 rubles, then this device is worth thinking about :-)

# zabatsay 04/16/2011 21:11
Good idea! Only the composition of WD-40, if I’m not mistaken, is white spirit, oil, and tricky additives. I'm not really sure that this thing will work well in compressed air. Need carbon dioxide. Need to try.

# dobryni 04/16/2011 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 remaining lubricant of the mechanism itself. So after cleaning, don’t forget about regular lubrication :-)

# dobryni 04/17/2011 02:53
Tested, cleans just as well. 2 flaws, does not leave behind protective film(the same additives) and it stinks terribly, but everything has its pros and cons
:-)

# DeOS 04/30/2011 21:42
I’ve never seen such an adapter, or maybe I didn’t pay attention, but it’s an interesting idea. By the way, is the smell from the desic still there?

# Dimka45kgn 06/16/2011 12:58
When I did it, I did it according to your instructions - I thought that I wouldn’t be able to remove the tube from the cylinder, but it turned out to be so simple, thank you!

# Vladickbeliy 01/28/2012 20:38
I also made such a thing from a freshener

# priborr 04/24/2012 13:30
and whoever made such a contraption, tell me: does it have to be an aluminum cylinder or will it be made of tin?

# kelendria 08/10/2012 23:01
better take a siphon. it is also made of aluminum. and there is no need to drill if there is no siphon. Homemade compressed air cylinder

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

# Trumkin 06/15/2012 18:14
Is it possible to immediately install a car nipple without an adapter?

# kelendria 08/10/2012 22:53
the balloon is bullshit. I made it simpler. I took an old siphon and screwed the nipple into the plastic cap. No need to drill or glue. and inflated it with a compressor. it turned out to be an awesome thing. you can buy an old siphon at a flea market or ask a neighbor - there is a lot of such crap in the mezzanines

#gra 01/26/2013 21:52
I have a question: can a 150-200 mm cylinder withstand 5-7 atmospheres? and it's kind of creepy.

# zabatsay 01/27/2013 04:54
Must endure. Such cylinders are designed for 30-40 atm.

# Gauss 02/14/2013 19:27
Good afternoon I made a 250 ml can from a can, pumped it up to 4 atmospheres, the pumped air is blown out in literally 5 seconds. How many atmospheres do you need to pump 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 with a car pump to 8 atm, the bottom of the bottle squeezed out and the nipple flew off. I screwed the nipple back with glue and the next day I pumped it again, but this time at 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. Such cylinders use either freon or liquefied natural gas. Essentially it’s like any aerosol can, only without the filler. take it from a deodorant - preferably the more, the better. more air. and you need to glue the nut in, and then screw in the nipple. After gluing, seal everything with sealant until the bottom is even. This way it’s more reliable and won’t wobble. Also glue in a tube from Chupa Chups - it’s more reliable.

I came to the conclusion that it is most reasonable to use a Siphon and cans with carbon dioxide, but I think it’s irrational to pump air into aerosol cans.

I invite everyone to speak out in

We are usually unenthusiastic when asked to dust off a computer or other household appliance that is full of hard-to-reach places. A can of compressed air does a good job with this task, but it is not sold on every corner. So it's better to make it yourself.

– tin or aluminum aerosol can;

– nipple from the bicycle inner tube;

– adapter for a car pump;

– epoxy glue (poxypol is best);

– drill, pliers, file, pump.

We take out the nipple from the old bicycle inner tube and grind off the edges (installation grooves) with a file - carefully so that the screw-in thread remains intact. We need the nipple to be perfectly round.

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 in the lower right photo (golden cylinder to the right of the cylinder).

Bend a thin wire into a hook and use it to pull it out plastic straw, located inside the can - we don’t need it.

The adapter will fit tightly into the hole prepared for it. Taking advantage of this, using pliers, carefully screw the adapter into the hole, creating a thread. The adapter should easily screw into and out of the hole. For now, unscrew it and set it aside.

Now we prepare the glue. The components of poxypol - glue and activator - are contained in separate tubes. Squeeze them onto a plate in a 1:1 ratio and mix them together with a stick (the plate and stick are included in the kit). Lubricate the nipple with glue and insert it into the adapter.

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

Screw in until it stops. Now the glue should dry for several hours (about a day).

When the glue dries, drill a hole in the spray can for the paste tube. The tube must be clean: wash it with acetone or some solvent. To ensure that it fits tightly into the hole and holds well, 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:

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

We aim our can of compressed air at the dusty interior of the entrusted to us household appliances and press the button. As practice has shown, the computer is well cleaned of dust.

This can will also be useful for this:

We prepare the necessary materials and tools:

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

We design

We bend a thin wire in the form of a hook and use it to pull out the plastic tube located inside the can - we don’t need it.

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

Screw in until it stops. Now the glue should dry for several hours (about a day).

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

Using the can as intended

Cans of compressed air often help restore life to faulty equipment. In most cases, it is thanks to cans of compressed air that many of us save significant amounts of money that we could have spent by taking the equipment to the service center. Spray can, of course useful tool in capable hands, but even skillful hands sometimes they cannot find it because it is not sold in every store. The question arises: what to do? Immediately after that comes the answer: make it yourself.

So, in order to make a can of compressed air with our own hands, we will need:
- Empty aerosol can;
- Nipple from a bicycle with a special adapter for a car pump;
- A tube that can be removed from WD-40 (you can also use PVC insulation removed from the cable);
- Epoxy resin.

The materials have been collected, you can begin. First of all, take the nipple and grind its edges.

Next, take the can. At its bottom we need to make a hole with a diameter of 8 mm. Through the hole made, you need to remove the standard plastic aerosol tube, since it simply won’t be needed. After this, we take the adapter for the car pump and begin to cut the thread in the hole we made.

The next thing is to take a drill with a diameter of 2 mm and begin to expand the aerosol nozzle to the diameter of our tube. You need to make sure that the tube fits tightly into the hole and also holds.

Next, take the bicycle nipple, coat it with epoxy resin and screw it into the adapter. As a result, we get one whole part, which in turn is the same epoxy resin screw it into the bottom of the can.

The can is ready. All that remains is to pump it up with air. You need to pump to the end of your strength, without worrying about the integrity of the can. The fact is that a person can manually pump air into a canister with a pressure of about 5 atmospheres, a car pump can reach a pressure of 10 atmospheres, an electric compressor will help double the result of a car pump, but even this will not damage the canister, which is designed for 40 atmospheres.

The only drawback of such an invention is that when the pressure drops, it begins to work not so well. To avoid the need to frequently pump air into the can, you can take a can from an air freshener or something else, as long as it is large.
