BEKO MDp 4 DRYPOINT Premium Membrane Air Dryer with Integrated Pre Filter, 4.18cfm

SKU: MDp 4
Part #: MDp 4

BEKO MDp 4 DRYPOINT Premium Membrane Air Dryer with Integrated Pre Filter, 4.18cfm

Compact, reliable and without need for external power: Membrane dryers use highly selective membranes to dry the compressed air. They are able to achieve pressure dew points between +15 and -40 °C and are therefore widely used for a wide range of application. In particular for operation under changing ambient conditions. The integrated nanofilter guarantees efficient filtration and protects the membranes.

Perfect for end use applications where clean dry air is a necessity. The MDp 4 membrane air dryer is adaptable to various ambient conditions. The DRYPOINTM intelligence is a drying system that guarantees a constant degree of drying even under fluctuating operating conditions. The sensor integrated into the control unit responds to changes in the operating pressure, the pressure dew point at the inlet and fluctuations in the compressed air demand. The display and control elements of the unit are integrated into the control panel. The control panel shows the current operating mode as well as the set degree of drying. A change of the operating mode or the degree of drying is possible at any time during continuous operation.

A membrane style air dryer acts as a dew point suppression style dryer, which will lower the dew point of the compressed air by approximately 30ºF depending on inlet conditions.

The integrated nanofilter element prevents the ingress of aerosols and solid particles. This is enclosed in a screw-in filter housing (housing extension) and installed directly in front of the hollow-fiber membranes.

The internal BEKO part number for this membrane air dryer is 4011795
