Central air pump intake kit
This kit provides a properly sized central
intake filter located on the compressor module
used to supply the intakes of the individual air
pumps. This extends the central filter
replacement interval (to every 2000 hours)
compared to the interval for changing the
filters on individual compressors, and ensures
simpler and faster central filter replacement.

9. PRODUCT FUNCTION
9.1. Compressor with adsorption
dryer
Fig. 1: Compressor aggregates (12) draw in
atmospheric air through the intake filters and
compress it through non-return valves into the
compressed air system. A connecting hose
(13) connects this system to the external
adsorption dryer (8). From the inlet to the
dryer module, the air is first cooled in the
integrated cooler (9) and then through the
condensate separator (10), entering the active
chamber with adsorbent (11), where the air is
dried. A portion of the air is fed into the
second, regeneration chamber, where this air
is used to remove moisture from the
adsorbent, after which it is released through
the silencer (21). The active chamber
switches on a cyclical basis. Dry and filtered
air then passes through the check valve into
the air tank (2). The treated compressed air is
ready for additional use in the air tank.

Dependence of compressor output on working pressure
FAD correction of capacity for altitude
Capacity given in the form of FAD („Free Air Delivery“) applies to the following conditions:
Altitude
0 m.n.m.
Temperature
20°C
Atmospheric pressure
101325 Pa
Relative humidity
0%
To calculate FAD compressor capacity in dependence on altitude, it is necessary to apply correction
factor according to the following table:
Altitude [m.n.m.]
0 -1500
1501 - 2500
2501 - 3500
3501 - 4500
FAD correction factor

0.80
0.71
0.60

INSTALLATION

INSTALLATION
Risk of incorrect installation.
Only a qualified technician may
install the compressor and
place it into operation for the
first time. Their duty is to train
operating personnel on the use
and maintenance of the
equipment. An entry is made in
the equipment installation
record to certify installation and
operator training. (see the
Annex chapter)
10. INSTALLATION CONDITIONS
The compressor may only be installed
and operating in dry, well-ventilated
and clean environments under the
conditions specified in the Technical
Data chapter.
Risk of damage to the device.
The equipment may not be
operated outdoors or in
otherwise wet or damp
environments.
Risk of explosion.
Do not use the equipment in the
presence of explosive gases,
dust or combustible liquids.
The compressor must be installed so
that it is accessible at all times for
operating and maintenance. Please
ensure that the nameplate on the
device is readily accessible.
The compressor must stand on a flat,
sufficiently stable base (be aware of
the weight of the compressor, see the
Technical Data chapter).
The compressor on the operator’s side
must be at least 70 cm from the wall to
allow air flow for cooling purposes and
to ensure the safety of the operator
and maintenance personnel.
Approximately 70% of the electrical
energy used by the compressor
aggregates is converted to heat, and
therefore the rooms in which the
compressor is installed must have
additional ventilation to provide
sufficient air exchange for cooling
purposes (see the Technical Data
chapter).
Burn or fire hazard! Caution!
Hot surface!
Portions of the compressor,
dryer and connecting hoses
between the dryer and
compressor may be hot and
reach hazardous temperatures
during compressor operation
that may harm materials or
operating staff.
High temperature hazard
Placing air flow impediments
upstream or downstream of the
cooler is prohibited. The
temperature of internal and
external parts of the equipment
may rise to hazardous levels.
You may notice a “new
product” odour when you first
place the product into service
(for a short period of time). This
odour is temporary and does
not impede the normal use of
the product. Ensure the space
is properly ventilated after
installation.
