DustAir™ is perfect for cleaning smoke detectors and electronic
equipment prior to detector testing, using either an Enclosed Delivery or Open
Delivery test head.
Note: The can will begin to cool after 4 to 6 of these 2-3 second bursts, and there will be a corresponding drop in efficiency. Therefore, if any number of smoke detectors need to be cleaned, you should have 3 cans of DUSTAIR™ to alternate, allowing the idle cans to warm to normal. Running warm water on the cans (or even body heat) will accelerate the process.
