Originally developed for industry as a way to protect workers from airborne particles, this system offers an effective, portable means to capture dust during woodworking or renovation.
The concept is deceptively simple: a bag made from a special synthetic fabric fits over a regular household fan and cinches in place with a drawstring closure. As air is drawn into the back of the fan and expelled through the front, the fine-weave material filters out 97% of particles as small as 5 microns. The air filtration rate depends on the size and speed of the fan (the greater the air-flow, the faster the rate of filtration). Easy to clean – just empty and machine-wash for reuse.
As with all dust-collection equipment, this is not a substitute for proper use of dust masks or respirators.
The medium Air Net fits round fans up to 18" in diameter; the large fits round fans up to 24" in diameter or square fans up to 20". Comes with a small drawstring bag of the same material, for compact storage.
