2.2 Understanding the Parts of the Product
2.3 Understanding Operation
The radial fan is designed for positive extraction of aggressive fluids
not containing foreign particles (low in aerosols, no dust) (see Sect. 1.1
and 1.2 for details).
The product version shown in Sect. 2.2 is to be fitted to the extraction
system/pipe with the flange at the suction side. This is possible thanks
to the light product weight. However, the preferred product version is
the one with a support bracket. This bracket covers the side of the fan,
supports the motor, and the flange is screw-fitted to it. The bracket is
meant to be fastened to a suitable surface in the extraction system,
using pulse dampers.
The fan is turned on and off by a manual switch to be sourced on site or
a higher-level air extraction control or management system. The motor
will be connected, through its mounting box, to that hand-operated switch
or the power supply circuit of that existing system.
The fan is designed for continuous operation. If (automatic) safety discon-
