Ship blower PPV-D1OX

for hazardous areasaxial

APPLICATIONS Typical application of this fan is mechanical ventilation of hazardous zones and rooms onboard ships. Duct-top, above deck mounting. DESIGN The PPV-D1OX is designed primarily for ventilation, both supply and extraction, of pump-rooms and other places where explosive fumes occur. The fan is spark proof with a totally enclosed, natural cooled and flameproof electric motor. Long experience has contributed to a simple construction with only one rotating part in addition to the motor itself. The propeller is mounted directly to the motor shaft, thus making it one unit with the motor flange which can be lifted out for inspection. EXECUTION Fan casing consists of welded steel plates of heavy duty design and includes guiding vanes for the propeller. The propeller and guiding plate are made of salt- and ammonia resistant alu-minium. Aerodynamically shaped and balanced. The wings can be inserted at various pitch angles to suit specified capacities and pressures. The mesh guard is made of stainless steel. Greasing-point for gas tight assembly is provided on top of the cowl. The PPV-D1OX can be de-livered in the range from size no 260 to size no 1250. ELECTRIC MOTOR The motor is totally enclosed, natural cooled and flameproof, designed for above deck mounting. Test certificates are delivered with each motor. CLASSIFICATION SOCIETIES The fan satisfy the demands of the various classification societies. ACCESSORIES - Counter flange - Protection grid
