Duplex Filter Housing (VH-DFH)

The Vens duplex filter housing has two filter chambers joined by a three-way changeover valve. One chamber filters while the other is cleaned or its element replaced, so the line keeps running. It is used on hydraulic oil, lubricating oil, fuel oil and process fluid systems.
