(L90RS - L132RS only)
The cooling air volume required by these screw
compressors is as follows:
Under unfavourable local conditions, we recommend
the installation of venting ducts. However, the velocity
of the cooling air should not exceed 5 m/s (17 ft/sec).
We recommend a minimum duct cross-section of
approx. 0.91 m
2
.
Important
The stated minimum cross-section refers to a
maximum duct length of 5 m (16.4 ft) and a
maximum of one bend. In the event of differing
values (over 5 m (16.4 ft), more than one bend, filter
cartridges, screens, etc.), please contact your
technical adviser.
CompAir screw compressors are rated for ambient
temperatures and cooling temperatures of +1°C
(33.8 °F) to +45°C (113 °F). In the case of
temperatures other than the above limiting values,
please consult your technical adviser.
Note
In order to ensure a good heat dissipation, auxiliary
fans should be rated to process approximately 15 to
20% more air volume than the total cooling air
quantity required by the compressors installed in the
compressed air station.

sections arrangement:
