L)
Since the pressure and current of the blower are in direct proportion, it is
necessary to install a pressure relief valve at the air suction/extraction port
to avoid overcurrent failure of the motor. The pressure relief valve listed
below can used in both compressor and vacuum applications.

Pressure and air friction can easily build up heat around the outlet of the
blower. To lead away the heat, an iron pipe at minimum 1 meter is thus
needed to be connected to the outlet.
N)
On the discharge side, the cover, impeller and silencer housing must not
come into contact with flammable materials (i.e. wood)
O)
The flow noise is reduced by build-in silencers. In the case of free air
intake or exhaust, the noise can be further reduced by attaching additional
silencers. In order to reduce noise emission even further, these units
should not be attached to components that conduct or radiate sound (such
as thin walls, metal plates etc.). If necessary provide intermediate sound-
absorbing layers.
