The filtration process is designed to use a low pressure source (15psi min -150psi max.) like a recirculating cooler or other pumps that do not generate pressures above 150 psi. The low pressure source pushes the hydraulic fluid into the filter housing where the 3-micron depth-type filter element absorbs free and emulsified water and traps solid particles. Once the fluid is filtered it exits the housing and is returned back into the tank. If the pressures are over 150 psi consult PFS for special flow control valves and relief valves.
PFS Guarantees after 200 hours of filtration the hydraulic fluid will be cleaner than brand new hydraulic oil.
The filtration process is designed to use a high pressure source (50 psi min – 3,000psi max.) Tee into the high pressure line and install a steel shutooff ball valve to isolate the filter housing when a filter service is required and then install a flow control valve (.5 gpm -2.0 gpm) to reduce the pressure down to 5 psi- 50 psi. The low volume low pressure hydraulic fluid will flow into the filter housing where the 3-micron depth-type filter element absorbs free and emulsified water and traps solid particles. Once the fluid is filtered it exits the housing and is returned back into the tank.
PFS Guarantees after 200 hours of filtration the hydraulic fluid will be cleaner than brand new hydraulic oil.
All heavy duty housings are made of carbon steel with a black powder coated finish inside and out with all stainless internal wetted parts. The industrial strength housings use a bolt down cover to ensure a rugged positive seal.
Best housing warranty in the industry. 10 years.
