Aerosol Duster

*=required field

Techspray Duster (commonly called "canned air", "compressed air duster", and "dusting gas") blows away dust, microscopic contaminants, lint, metallic oxide deposits and other soils that can damage sensitive electronics. When these contaminants get in the way of vents or fans within the device, they create a build-up which leads to overheating and/or shortages. 

Techspray dusters do not contain additives that can contaminate sensitive electronics. Retail dusters generally have bitterant added to prevent huffing. This same bitterant can lead to unwanted and potentially harmful residues that can build up over time.

Choose the air duster propellant that best meets your needs:

  • HFC-134a – Most common for industrial applications because it is nonflammable. Intended for cleaning energized circuits.
  • HFC-152a – Most commonly available duster in consumer retail because it is less expensive than HFC-134a. It is flammable, and will ignite when concentrated (i.e. in liquid form) and exposed to a spark or flame. 1/10th the global warming potential (GWP) of HFC-134a.
  • HFO-1234ze – A newer propellent that is nonflammable, and a much lower GWP than either HFC-134a and HFC-152a. Ideal for ISO-14000 programs.

FAQ's

How can I stop a can of “canned air” aerosol duster from freezing up?

This phenomenon occurs due to the expansion of the compressed refrigerant liquid as it dispenses through the aerosol valve and flashes to a gas. If the aerosol is operated for a long period, frost may form on the can because it is freezing the surrounding water vapor from the air. If it is collecting on the material to be cleaned, the operator is dispensing for too long of a period or is dispensing it too close to the material. The frost will evaporate and leave no residue. However, particulate matter blown onto a sensitive surface may cause damage due to the high pressure of the duster if dispensed too closely to that surface.

How do you use air duster (canned air)?

The can of duster must be held in an upright position when spraying. Do not tilt can more than 40 degrees during spraying operation or shake during use. Before use, press actuator to clear valve of any liquid product. Extension tube can be used to remove dust in tight areas. Use short bursts to prevent cooling of can.

What is the shelf life of air duster (canned air)?

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.
