Nominal dryer capacity according to DIN ISO 7183, Pressure dew point -40 °C
The capacity of the dryer is based on the intake volume of the compressor at 20°C, 1 bar (a). 
Subject to alteration without prior notice

The above-listed dryer capacities are based on standard operating conditions:

Pressure at dryer inlet: 7 bar (g)
Temperature at dryer inlet: 35°C
Pressure due point at dryer outlet: -40°C

Deviations from these operating conditions might affect the performance of the dryer. To calculate the capacity under the "worst case" operating conditions (lowest inlet pressure, highest inlet temperature, lowest required pressure dewpoint) please use the correction graph.


Selection example:
Pressure at dryer inlet: 4 bar (g)
Temperature at dryer inlet: 45° C
Pressure dew point at dryer outlet: -20° C
Following the red arrows from 45'C to -20'C then down to the 4 barg line, we find a correction factor of 0.78.
The dryer capacity will be reduced to 78% of the maximum dryer capacity.
The blue arrows show a correction factor 1 for standard operating conditions.

How to select the right dryer:
Compressor capacity = Required dryer capacity
         0.78
