Brief description The duplex filter is casted as a single component and comprises two identical single filters wich are connected via a cock-switching device. The medium to be filtered enters the filter basket from the top and flows through the insert inside out. Dirt thus remains in the filter element. Installation in pipes is done by means of flanges. Ensure that the standard version of the filter is installed vertically and mechanically tension-free without additional loads. The medium must flow in the direction specified on the housing. Incorrect installation can cause filter malfunctions and...

Important information for switchover Note: Since it is a pressure vessel, it is important to ensure that the filter is without pressure prior to beginning of maintenance. 1. As soon as the filter side is dirty (increasing differential pressure on the indicator or decreasing operating pressure in the system), the clean filter side is put into operation by gradual switching of the plug valve.* 2. Important: If the filter is build with a pressure equalization line (see picture on page 6), then open line for easier switching and close again after change-over. 3. Proceed with cleaning (removal of...
