•
in case of suction in the place or on the system, protect the intake pipe using a suitable
filter
with maximum filtration of 25µm.
For the use of filters with filtration different from 25µm, ask FPZ. Check compliance with the maximum pressure / vacuum data
giv
en in the SPECIFICATIONS (max ∆p).
•
for use as a
blower
deduct the pressure loss (P
a
) from the
maximum compression indicated (max ∆P ), i.e. P
working
≈ max ∆P -
P

(for T
ambient
=20°C and P

=1013 mbar)
•
for use as an
exhauster
make sure the maximum vacuum at the inlet port is not exceeded.
SPECIAL VERSIONS
3.2
FPZ side channel blowers/exhausters can be manufactured in special or custom versions; the instructions given in this manual still
apply to some of them.
The special versions manufactured, and for which that given above applies, are:
•
BPA version
Machines built to work in harsh environments and/or for conveying aggressive fluids, where aggressive means the presence
of elements that can affect standard machine operation, such as humidity; as specified in point 2, conveying flammable,
explosive or toxic gases, or installation in potentially explosive places, is not permitted.
•
TMS version
Machines that ensure mechanical seal between the parts that convey air or fluids, minimising leakage.
•
Special electric motors
On request, blowers/exhausters can be manufactured with motors having one or more of the following characteristics:
-
Special voltages
-
Higher levels of protection against solid bodies and/or liquids (standard IP55)
-
Higher insulation classes (standard Class F)
-
Protection devices such as thermal switches, heaters, PTC, PT100
•
Energy Efficient motors
The side channel blowers/exhausters can be manufactured using high efficiency, premium efficiency.
Further customisation must be requested and agreed when ordering, subject to a feasibility appraisal by the Technical Department.
