CHEM-PROOF STATIONARY FAN
WPA-CHEM
04.06.2019
The fan is efficient in horizontal application an
d in ambient tempe40ºC. On demand
are delivered motors adapted for operation in ambient temperature up to +60ºC.
Both, the fan housing and motor are installed on the base. The base is a welded construc-
tion of steel angle bars.
The plate underneath the motor is made of strengthened steel sheet. In the lower part of the
base are located mounting holes to install the fan on a foundation.
The cover of the inlet and outlet protects User from accidental contact with the rotary fan ele-
ment. Covers (guards) are prepared of steel wire in a form of grill.
On demand, are delivered isolating switches, to cut off the power supply during the installing,
servicing (see catalogue card “Electrical Accessories”).

Assembly and Start-up
The fan is delivered in a completely assembled state. Prior to installing, examine if the deli-
vered fan was not damaged or polluted during the transport.
The hole pattern of the foundation ought to be strictly according to the distribution of suitable
holes in the fan base. Additionally, the holes placement of the inlet and outlet should be
suitable with adequate holes of the ventilation ducts. The fan must be placed strictly horizon-
tally (if the device is not levelled, use washers to obtain appropriate positioning).
Moreover, it is important to tighten up evenly the foundation screws. Ventilation ducts must
be connected in such a way, that they do not charge the inlet- and outlet flange (of the fan)
with excessive load. Therefore, use flexible connections.
Before the connection to the power supply, make sure whether the parameters of the
existing electrical installation are in accordance with the data on the nominal plate.
Otherwise, in case of inconsistency the connection cannot be executed.
