Structure and Function
The fan consists of a steel spiral housing and a motor and a radial impeller which is directly
mounted on the motor shaft (direct drive).
The structure rests on a base frame structure.
The
inlet and outlet are adapted for connection of the flexible hoses,
which
are clamped with hose
clamps. For safety reasons,
the
inlet and outlet are equipped with a protective grill. The impel-
ler with profiled radial blades provides low acoustic pressure of the fan.
As standard
, the fan is equipped with a motor protective switch
.
Each fan is energized through
a five metre long power supply cable with a plug.

Assembly and Start-up
The portable WPA-P-N fans can work in closed rooms
(indoor application)
and outside the buil-
dings. In case of outdoor application (especially for a longer time of operation) it is important
to protect the device against atmospheric factors.
