High capacity, portable 1000 watt 120 VAC electric air turbine w/thermal overload protection
Rheostat dial allows you to control the amount of air flow
Bypass, tangential discharge air turbine
Does not heat up your breathing air
Dual filters - 1 for breathing air, 1 for motor cooling air
Will support 300' air hose with 3/4" ID smooth bore for 1 worker with tight fitting facepiece, 200' for loose fitting hood, 150' apiece for 2 workers with tight fitting facepiece, or 100' apiece for 2 workers with loose fitting hoods
I recommend you purchase the in-line flowmeter to ensure you are getting proper air flow to your hood/mask/helmet.
