Off-Line Filter

Off-line filter system is connected to the reservoir of a hydraulic, lube or storage system and operates independently from the system it’s attached to. This means that it can be stopped for an element change without interrupting operations. It allows the flexibility to use ultra-high efficiency media to remove particulate and insoluble to reach low ISO codes that might otherwise be unattainable.

Conditioning off-line filter system extends the life of the critical on-board pump discharge and the reservoir protects the pump inlet, eliminating the need for suction strainers that can cause pump cavitation. Let’s take a look at the different types of offline filtration products, dedicated and mobile.

Dedicated Offline Filters – A properly sized offline filtration system can turn over the entire volume of a reservoir several times a day (we recommend 8 turns), maintaining ISO fluid cleanliness codes well below the upper limit. Whether you’re using low viscosity hydraulic or high viscosity lube oil, implementing dedicated offline filtration will yield longer bearing and hydraulic component life and longer useful fluid life.

Mobile Offline Filters – Portable filtration systems are a valuable tool in the battle against contamination and are ideal for fluid transfer and in-field service work. The Hy-Pro range of portable filtration systems includes compact units for small gearboxes, filter carts optimized for hydraulic applications and units with generously sized filters for high viscosity or highly contaminated fluids commonly found in fluid reclamation.

Implementing offline filtration is the best way to ensure your hydraulic and lube oils are clean and your systems are operating efficiently. Whereas applications that consume fluids (diesel, etc.) must filter fluids in a single pass, offline filter systems for hydraulic and lube oils allow for recirculating the reservoir to remove more dirt with every pass.
