Typical application for this fan is mechnical ventilation, extraction, in hazardous zones of cargo area and rooms onboard ships. Duc-top, above deck mounting.

From the Det Norske Veritas system requirements, mechanical ventilation in cargo area:

A 100 General.

109 Electric fan motors are not to be installed in ventilation ducts when the ship has to carry flammable products.

111 Ventilation outlets from gas-dangerous spaies are to discharge upwards in location at least 10m in the horizonal direction from ventilation intakes and openings for gas-safe spaces.

DESIGN

The PUV-D1RX is designed primary for ventilation, 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

The propeller, fan casing, motor flange and guiding plate are made of salt- and ammonia resistant aluminium. The propeller is aerodynamically shaped and balanced with various pitch angles to suit different pressures and capacaties. The wire mesh guard is made of stainless steel.

Greasing-point for the gas tight assembly is provided on top of motor flange. The PUV-D1RX can be delivered in the range from size no 260 to size no 1100.

ELECTRIC MORTOR

The motor is totally enclosed, natural cooled and flameproof, designed for above deck mounting. Test - and Ex certificates are delivered with each motor.

CLASSIFICATION SOCIETIES

The fan satisfy the demands of the various classification societies.
