The cooling air volume required by these screw
compressors is as follows:
L30 2296 cfm
L30RS 2296 cfm
L37 2755 cfm
L37RS 2755 cfm
L45 3073 cfm
L50 3073 cfm
L45RS 3073 cfm
If conditions are not favorable, we recommend the
installation of venting ducts. However, the velocity of the
cooling air should not exceed 17ft/sec. We recommend a
minimum duct cross-section of approx. 6 ft
2
.
NOTICE
The stated minimum cross-section refers to a
maximum duct length of 16.4 ft and a maximum
of one bend. In the event of differing values
(over 16.4 ft, more than one bend, filter
cartridges, screens, etc.), please contact your
technical adviser.
Gardner Denver screw compressors are rated
for ambient temperatures and cooling
temperatures of 33.8 °F to 113 °F.
In the case of temperatures other than the
above limiting values, please consult your
technical adviser.
NOTICE
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.
