Filter housing - PI3730-069/PIS 3155 *E77681042

Medium pressure duplex filter housing – Pi 370 series

The PI3730-069 / PIS 3155 from Filtration Group is a heavy-duty duplex filter housing designed for continuous filtration in hydraulic and lubrication systems. It is engineered for applications where high cleanliness, reliable operation, and filter change without downtime are essential.

The housing is used as an OEM solution and corresponds to DMG MORI ID no. 2586105, making it ideal as a direct replacement or service component for machine tools and industrial systems.

The compact design and aerodynamic internal flow path ensure minimal pressure loss and high efficiency – even at elevated operating pressures. The ergonomic change-over lever with locking mechanism and pressure compensation allows safe and easy filter change during operation.

The housing is equipped with an electrical and mechanical differential pressure indicator for precise condition monitoring and timely maintenance. With a robust cast iron head and steel housing, the unit is ideal for demanding industrial environments.

The housing is perfectly matched with high-performance filter elements such as ScandiFILTER HF-83.5/255-SS60-30-SS-SOE (SKU 70890).
