5.7 Air outlet
The pressure loss at the air outlet due to air after-
coolers, fittings, piping, etc.should be as small as
possible.
Note:
Cross-sections of the outlet pipe must be gener-
ously dimensioned. Avoid pressure losses due to
elbow screw fittings.
The outlet pipe must be connected stress-free to
the outlet.
Warning:
Serious injuries and damage are possible in case
of operation without a safety valve!
Operation without a safety valve on the separator
tank is not permitted.
Note:
A possible compressed air temperature (at the
outlet) of up to 110°C/230°F requires the compo-
nents connected downstream, e.g. the com-
pressed-air hose, pressure switch, air after-cooler,
fittings, etc. to be designed for this temperature.
We therefore recommend the installation of an air
after-cooler.
When used without an air after-cooler, the high
outlet temperature must be pointed out to the final
customer.
5.8 Oil cooling
Note:
The cooler connection lines must be connected
torque-free to the oil connections.
The following information on the design and exe-
cution of the oil cooling system must be observed.
– The oil cooling system must be designed so
that the oil outlet temperature is a maximum of
105°C/220°F at the maximum intended ambi-
ent temperature.
– The oil circulation quantity is dependent on the
pressure difference between the outlet and the
inlet pressure of your application.
– The oil cooler must be installed so that it can be
cleaned easily.
– When designing the cooling system, the pres-
sure dew point graph (Figure 8-1) must be
taken into account.
If questions arise concerning the pressure dew
point, please contact ROTORCOMP.
5.9 Service
Ensure good accessibility to the service points
when installing the screw compressor air end sys-
tem in a housing:
– Oil filling point
– Oil drain point
– Removal of the separator cartridge (removal
dimensions according to offer drawing)
– Removal of the oil filter cartridge (observe the
removal dimensions specified in the offer draw-
ing)
– Easy cleaning of the oil cooler
– Replacement of the shaft seal (removal and
installation of the end cover and the bearing
race)
– Belt drive (accessibility, specifications for cor-
rect belt tension)
