Ventilation
1.
Installation area of the compressor must be
ventilated at all time for efficient operation.
While operating the
compressor, ventilate the
workplace to maintain the temperature in the range of
35-104°F. Operating the compressor with ambient
temperature above 104°F will damage the compressor
and will cause shut down of the equipment.
Temperatures above 90°F decrease the product. Cooler
temperatures increase operating efficiency, decrease
the product reliability, and requires reduced
maintenance intervals.
2.
For general ventilation, as in the figure below, the
minimum amount of ventilation required to
prevent temperature rise is 16,500cfm for model
PCC500.
3.
When installing ventilation fans, consider the
positions of cooling air inlet and cooling air outlet.
Inappropriate installation of fans will disturb the
air circulation in the workplace and may affect
performance of the compressor.
4.
The ventilation air speed at cooling air inlet must
be slower than 980 ft/min.
Local ventilation A (auxiliary duct with no fan)
A duct only, without a fan may be utilized to
channel warmed cooling airflow out of the
compressor room if the duct backpressure is below
0.11 inches WC. At a flow of 4240 scfm.
In order to facilitate
maintenance and repair, a
flexible connection must be installed that is removable
at your convenience, as shown above. Make sure that
duct weight is completely supported by the wall or
ceiling, not by the compressor enclosure.
5.
For local ventilation B (duct installed with a
ventilation fan), refer to the figure below
for the
details.
