5. Structure and Function
The roof fan type WP-…-D/Ex has a spiral housing made of non-magnetic austenite and
stainless steel. Outside the housing, in its axis is perpendicularly fastened a flange motor
in Ex execution.
On the pivot of the motor shaft, inside the housing, is installed a radial impeller also made
of austenite, non-magnetic stainless steel.
Inlet (suction) is located in the axis of the housing spiral, opposite to the motor, whereas
the outlet (air supply) is at the end of the housing spiral.
The fan inlet and outlet are equipped with a protective grill. The fan inlet is the suction
connection in a form of double frame of steel sheet
serving for installing the fan on the place of operation, (mounting: 6 bolts M6 or 8 bolts M8
depending on the type of the fan).
The fan has to be installed on a roof base or a wall bracket. The fan outlet is equipped with
silencer made of austenitic, non-magnetic and stainless steel sheet.
ADDITIONAL EQUIPMENT –delivery on separate order:
wall brackets
silencers.
To the fan housing is fastened a protective cable to lead the electrostatic charges away.
On the motor housing is located a clamp to fasten the protective cable.
