feature an
original construction of bent steel profiles, making up a ske-
leton of streamline and robust properties. Inside is located a motor with a radial impeller.
Lower skeleton
is
surrounded with a circumferential
wire net,
providing an openwork structure
through which
the air is discharged
. Under the lower skeleton is
located the fan inlet with a flan-
ge serving as a mounting element to the roof base.
Manufacturer suggests installing on sound absorbing roof bases TPD or TPDC,
or eventually
on standard roof bases BI or BII.
Additionally
, on demand of Customer,
are delivered rotation speed governors type RP for step-
-less adjustment of the fan flow efficiency.
Upper parts of the fan are shielded by a plastic hood.
