For compressors from 22 KW: The belt must be tightened and may only yield up to a
maximum of 4-5 mm at an applied force (F) of 35 N
(Figure 7).
8.3.8 Checking the intake filter (filter element)
The compressor requires a large volume of air for operation and internal ventilation /
cooling. Therefore, an excessive amount of dust in the air leads to a malfunction in
the normal operation of the compressor. A certain amount of dust remains in the air
intake, meaning that it clogs quickly. The dust settles quickly on various internal
modules and components, including the air / oil cooler, and hinders the heat
exchange / cooling process. For this reason, it is important to check the air intake
before operation and to clean the work area regularly. This is the only way that the
normal operation of the system can be ensured and unexpectedly high maintenance
costs avoided.
DANGER: IF THE AIR IS MIXED WITH ORGANIC AND MINERAL DUST OR
CORROSIVE CHEMICAL VAPOUR,THE COMPRESSOR MUST BE
IMMEDIATELY SUPPLIED WITH CLEAN / FILTERED AIR.
8.3.9 Replacement of suction filter (filter element)
This must be performed every 500 hours or at least three times per year. Proceed as
follows:
•
Open the cover to access the air filter.
•
Loosen the wing nut and hold the cover of the housing secure.
•
Remove the air filter element and install a new one.
•
Replace the cover and tighten the wing nut.
