Adjusting dryer’s capacity for different operating conditions

The capacity applies to a working pressure of 7 bar, a compressed air temperature at the dryer’s inlet of 35°C and an
ambient temperature of 25°C, according to DIN ISO 7183. In order to calculate the dryer’s capacity for real operating
conditions at the dryer’s inlet, please use the following correction coefficients:
Capacity (air compressor) х F х F х F = Capacity (dryer).
