Product Description

In-Line High Pressure Filter (HFM Series 5800 PSI)

Features:

• The HFM filter is available in two sizes comprised of two different bowl and element lengths. The models 75 and 95 provide
maximum flow rates of 29 and 37 GPM respectively.
• A quick-response by-pass valve located in the filter head, protects against high differential pressures caused by cold startups,
flow surges and pressure spikes.
• The high bypass pressure setting (100 psid) minimizes the possibility of contamination due to premature bypassing.
• Filter materials are compatible with all mineral, lubricating oils, and commonly used fire retardant fluids per ISO 2943.
• Fatigue pressure rating equals maximum allowable working pressure rating.
• Wide variety of indicators available with standard setting of 72 psid (5 bar).
