Product News: Lightweight EFDA Duplex Filter Series

For industrial applications where it is necessary to keep the system running while performing maintenance and filter element change tasks, we recommend a duplex filter with two separate filtration chambers in one assembly.

New In-line Duplex Filter: low pressure filter for continuous operation

As addition to our portfolio we introduce the new change-over filter series EFDA, as lightweight equivalent to the EFDM high pressure duplex filter series.

For hydraulic systems with low operating pressure and high flow rates, the EFDA is a suitable match. The aluminum housing not only provides the advantage of being a lightweight alternative, but also reacts to growing demands of a cost-efficient filtration solution for industrial applications.

Function and Features of the EFDA

Both filter elements are assembled parallel with horizontally located inlet and outlet. The handle to operate the change-over valve is centered between both interconnected filter heads. Safe operation of the handle, also with one hand, is ensured by the integrated pressure equalization line.

Equipped with a differential pressure clogging indicator, the filter elements’ condition can be monitored either visually or remotely via electric signal. Thus assuring optimal protection of critical system components. The integrated flow change-over valve as well as the check valves at both elements outlets are 100% tested for leakage during assembly to ensure that there is no leakage during servicing of the contaminated filter side.
