Structure and Function
The fan consists of a spiral steel housing and motor with an impeller that is directly installed on
the motor shaft. The fan
is mounted
on a stand supported on a vibro-absorbing base frame
(see
Fig. No.1)
.
The vibro-absorbing frame interrupts the fan vibration transforming onto the floor and it is selec-
ted according to the weight of the fan-stand-frame set.
The fan inlet
is equipped with a flange, whereas the
outlet is secured with a round fitting piece for
attachment of the spiral-seam ducts or for flexible connectors.
For safety reasons, the inlet and outlet are equipped with protective grills. It is recommended to
install silencers TK at the inlet and outlet of the fan
(see Technical Data
Table No.1). The subse-
quent elements of the fan are assembled together.
