Euramco's RamFan AFi50XX is a 16 in. Intrinsically Safe Air Driven Blower engineered specifically for hazardous work environments where explosive atmospheric conditions make intrinsically safe equipment an absolute requirement. This pneumatic blower has an air motor made by Gast, and is powered by compressed air. Anti-static, glass reinforced ABS housing is corrosion and chemical resistant. Includes 1 reversible 16 in. 40cm duct adapter for attaching conductive ducting to either the intake or exhaust side of the blower. The compressed air powering the unit exhausts outside of duct, not in airstream. Complete with filter, motor lubricator, exhaust muffler, air control valve and static grounding cord.
