These Hazardous Location Blowers combine aerospace fan design with high-strength polymers. RamFan offers a rugged, high-output line of portable blowers for hazardous ventilation. When conditions become dangerous, our tough, conductive ABS housing adds static dissipation to its properties. UL® listed intrinsically safe motors meet your demanding expectations. Advanced blade design increases head pressure and provides the power you need to meet your "difficult to ventilate" conditions.
