Introduction: How to Make a Compressed Air Can

https://www.youtube.com/watch?v=_wO3Jpglj1E&feature=youtu.be

Step 1: To Do a Compressed Air Can You Need!

In this instructables I will tell you how to make a home made reusable compressed air barrel out of a spray can.

Step 2: All the Sprays Are Highly Efficient Where There Is Impossible to Use Liquid Cleaners.

Step 3: Cleaning With a Compressed Air Is a Safe Procedure, It's Harmless for Plastic and Other Sensitive Components.

Step 4:

Step 5: A Hand Made Compressed Air Barrel Will Help to Clean the Dust From Inaccessible Places, Such As Printing Units, Keyboards and the Rest Household Appliances, and So On, and a Channeled Stick Will Make Your Work Easier.

Step 6: It Doesn't Require Plenty of Efforts to Make Such a Barrel at Home!

very cool!

Can this compressed air be used to freeze water??

I applaud you method of soldering the valve in place instead of glue. I also like the location in the bottom better than other instructables that have it in the side.

BUT ... this and all similar instructables seem to omit the fact that this is NOT the same as a can of 'dusting spray' and will not perform at all close to the same as a 'canned air/dusting spray'. This is a can of compressed air which will run out VERY quickly. The disposable can is now a pressure vessel and modifying it has the potential of weakening it. Failure because of errors, workmanship issues, or that fact of modifying it can cause it to fail and explode. All very hazardous.

Below is part of a post from a similar instructable:

I hope that everybody understands that 'canned air' is not air, but a liquid hydrocarbon under pressure that becomes gaseous when released to normal atmospheric pressure. A popular material used in 'duster cans' is 1,1-Difluoroethane, with the chemical formula C2H4F2. , Also known as Refrigerant R-152a. R-152a has a vapor pressure of 63 psi at 70F. So the pressure in those duster cans is normally around 63 psi. A can of R-152a will last eons longer than a can of true compressed air because a can full of liquid R152a expands a vast amount when it changes to a gas.

Everyone just needs to have their expectations match the laws of physics. I don't think the hazard of modifying the can is worth the limited usefulness of the end product.

RS sold such items years ago, they had never work. Unfortunately, there's not enough volume to stock air, even compressed, it is still gas ! It works for less than 3 seconds and the pressure is really weak, nothing compared to liquid atomizers.
