FilSon Low Pressure Duplex Filters (LPDF) provide a simple and cost effective way to separate particle impurities from hydraulic & lube oil systems.
They are ideal for applications where continuous flow must be maintained, with no flow interruption for strainer basket cleaning. The surface of the duplex basket filters are treated with phosphorus and painted using polyurethane top coating. Transfer valve and convenient bleed valve provides smooth changeover.
- Maximum flow rate of 2500 l/min
- Numerous connection variants
- Bypass-valve, clogging indicators
- High capacity with low-pressure drops
- Carbon steel or stainless steel strainer optional
- Ball valve, poppet and cam-operated valve are available

All FilSon duplex filters and duplex basket strainers are subjected to strict air-tight and leak testing.
We use high-quality hydraulic fittings and duplex filter housing that allow for quick set up and minimal oil spills.
There is a ball valve changeover and a contamination indicator for protecting the hydraulic system safety and reliable seals. Its flow rate is 2500 l/min and a maximum pressure up to 1.6 Mpa.
