EVOTEK Hydraulic Technology recommends a duplex filter with two separate filtration chambers in one assembly for industrial applications, which require regular maintenance, and filter element change tasks.
As addition to the portfolio, the company has introduced a new change-over filter series EFDA, as lightweight equivalent to the EFDM high pressure duplex filter series.
The EFDA is a suitable for hydraulic systems with low operating pressure and high flow rates. 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.
