Red Devil Blower
 
Although there were several portable blowers used for desmoking, the most commonly used onboard ships was the red devil blower. A reliable piece of equipment, it was required on all Navy surface ships. A minimum of two, with four vent ducts each, were provided on hull and repair locker allowances for each DC repair locker. The power source for the red devil blower was 110 volt. The unit was outfitted with a 50-foot electrical cord with a 3-pronged connector. The capacity of the fan, using 3 lengths of 8-inch hose and with 15 feet of ventilation ducting attached, was 500 cubic feet per minute (cfm). The blower’s motor, when assembled at the factory, was explosion proof. The explosion-proof quality, however, was not necessarily present after overhaul of a motor. As an alternative in an explosive atmosphere or where there was the possibility of explosive vapors being present, either the pneumatic (air turbine driven) blower or the Lamb air mover were used. Planned maintenance (PM) was conducted by electricians; when the maintenance of the blower rendered it NOT explosion proof, the inside and the fan were painted yellow.
