*=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. 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. 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. 

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.
 
Techspray freeze spray blast fast-evaporating liquid that super-chills isolated areas. Used as a troubleshooting aid for intermittently faulting capacitors, resistors, semiconductors, and other defective components. Freeze spray also increases the visibility of cold solder joints, cracks in printed circuit boards and oxidized junctions.

Choose the freeze spray that best meets your needs:

  • HFC-134a: Nonflammable and most common for industrial applications.
  • HFO-1234ze: A newer propellent that is nonflammable, and a much lower GWP than HFC-134a. Ideal for ISO-14000 programs.
  • Antistatic: Nonflammable HFC-134a propellant with a small amount of antistatic additive to prevent static generation that can damage sensitive components.

FAQ's

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.

Are there differences between air dusters (canned air)?

There are different options for duster propellant: HFC-134a: Nonflammable, most common for industrial applications when spraying energized circuits because of the risk of a spark lighting a flammable material. It is under close scrutiny because it has a Global Warming Potential (GWP) of 1400, so 1400 times the impact of CO2. 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. HFO-1234ze: This is a newer, nonflammable material introduced in the last 10-years as a very low GWP alternative (<1) to HFC-134a. It is non-flammable and is almost indistinguishable from HFC-134a when sprayed, but unfortunately at a much higher price.
