Blast Dust & Dirt Off Sensitive Electronics

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. It has one-tenth 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.

How can I avoid static build-up when using duster?

The duster vapors themselves do not produce much of a triboelectric charge. There isn’t a non-contaminating additive that can be added because it would just stay at the bottom of the can (the vapors are at the top, which are released when you open the valve).

The liquid propellant can produce a charge, and the plastic actuator can become charged as well. There are a few solutions to consider:

  1. Anti-Static Freeze Spray can be used upside-down as a duster. The vapor itself won’t be any different, but if the can is mistakenly turned, the liquid is much less likely to be charged.
  2. Vortex 360 is an invertible can, so it is designed to avoid spraying liquid regardless of how the can is turned.
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.


Cleaners Developed to Minimize Global Warming Effect
With global warming in the news and greenhouse gases getting more regulatory attention, electronic and industrial manufacturers are on the look-out for ways to reduce carbon emissions. Techspray has been developing products for over a decade that have much lower Global Warming Potential (GWP), witho...
