Is canned air the same as compressed air?

Air Duster, also called “canned air”, “compressed air”, and “dusting gas”, is used to provide a pressurized blast, knocking loose dust and dirt. Think of it as a portable replacement for an air compressor line.

Does canned air last forever?

If the can and valving is intact and undamaged, it will not leak or spoil, so can sit on a shelf for as long as 10 years.

Should you use canned air?

Canned air should never be used in small or poorly ventilated areas – the gas is much more likely to become concentrated and create a flammable atmosphere. In addition, ignition sources – including electrical switches, flames and sparks – should be kept clear of the work area to help prevent fires.

Does canned air damage electronics?

Compressed (canned) air will do absolutely zero damage to your computer, even if you get the refrigerant (the stuff that blows out the nozzle when the can is sideways or upside-down) on your CPU/GPU/RAM/Motherboard.

What PSI is a can of compressed air?

145 psi
The maximum pressure for an aerosol can is typically 10 bar (145 psi) at 20 C (68 F). Therefore, a fully compressed air duster will exhaust air about 10 times the can volume.

Is compressed air bad for electronics?

Yes it is safe to spray compressed air into electronics as long as the electronics are OFF before you spray into them. Be sure to hold the compressed air can vertical while pressing its ‘air-release’. The can must be held upright during use.

Can a can of compressed air explode?

It can if used improperly. Aerosol dusters contain pressurized refrigerant, not breathable air as the common names (e.g. “canned air”, “compressed air”) for it suggests. Keep the cans away from high heat and flames, and avoid puncturing the can.

What are the safety risks associated with using compressed air equipment?

Compressed air can break through skin and cause minor injuries, but if the air enters into the bloodstream, and travels to the brain or heart, stroke or heart attack symptoms can occur. Blowing air from a compressed air system into your mouth can cause ruptures in the lungs or stomach.

Why can’t you shake canned air?

According to 3M, which manufactures and sells compressed air canisters for dust removal, shaking or tilting the can may result in propelled liquid instead of vapor. If this happens, the liquid may come into contact with skin or eyes, warns 3M, and cause frostbite because the chemical will freeze skin.

What is the liquid that comes out of canned air?

Most duster contain refrigerant that is liquid when held under pressure. The goal of duster is to spray the vapor not the liquid, so the valving is designed to capture the vapor from the top of the can. When you shake a can, turn it, or flip it upside-down, you can introduce the liquid refrigerant to the mix.
