Abstract
The dryer for compressed air comprises a filter bowl (,), which has an inlet (,) for damp compressed air, an outlet (,) for dried compressed air, a scavenging air inlet (26) and a scavenging air outlet (,). A membrane is accommodated in the filter bowl (,). The membrane lets selectively water steam flow through and has two sides. One side of the membrane is stroked by the compressed air, while scavenging air flows on the other side of the membrane. A feeder pipe (,) is provided, through which dried compressed air coming from the outlet (,) is fed into the scavenging air inlet (,). A closing device (,) is arranged in the feeder pipe (,) and has a closed position. The closed position depends on the consumption of compressed air in such a way that more or less scavenging air is made available when more or less compressed air is taken by a consumer device, operated by dried compressed air.
