Technical specifications

Models

Operating conditions: inlet air temperature up to 45 °C, working pressure 0.4–1.0 MPa.

How to select

A desiccant dryer is needed when the dew point of a refrigerated dryer is not low enough. AO and AA filters are installed upstream and a dust filter downstream.

Questions and answers

How often is the desiccant replaced?

Service life depends on inlet air quality and oil protection; with correct filtration the desiccant lasts several years.

Can it be installed after a refrigerated dryer?

Yes, this arrangement reduces the load on the desiccant.
