Description
Install the compressor on a level floor suitable for taking its weight.
Compressed air outlet valve (not in scope of supply).
Delivery pipe:
The maximum pipe length can be calculated as follows:
5
L = (dp x d x p) / (450 x Qc
L = Length of pipe in m
dp = Pressure drop (recommended maximum = 0.1 bar)
d = Inner diameter of the outlet pipe in mm
p = Absolute pressure at the compressor outlet in bar(a)
Qc = Free air delivery of the compressor in l/s
The connection of the air delivery pipe is made on top of the main air net pipe in order
to minimize carry-over of possible condensate residue.
Ventilation:
The inlet grid(s) and ventilation fan must be installed in such a way that any re-
circulation of cooling air to the compressor is avoided. The air velocity to the grid(s) has
to be limited to 5 m/s
The maximum allowable pressure drop over all cooling ducts together is 30 Pa
The maximum air temperature at the compressor intake opening is 46 °C (55 °C for
HAT version), minimum 0 °C
The required ventilation to limit the compressor room temperature can be calculated as
follows:
Qv = 0.1N / dT
Qv= Required ventilation capacity in m
N = Shaft input of the compressor in kW
dT = Compressor room temperature over the outdoor temperature in °C
Drain pipes to condensate collector. The drain pipes may not enter in the collector.
Individual drain pipes may not be interconnected to avoid interference
Compressor condensate contains oil. Depending on local legislation, it is recommended
to install an oil/water separator (consult Atlas Copco)
