Type SFA Medium Pressure Filters
SFA series Medium Pressure Filters are designed for in-line hydraulic applications with a maximum operating pressure of 160 bar / 2,320 PSI. A high efficiency of contamination removal is assured. The dirt-hold capacity of the elements ensures long service life, and as a result, reduced maintenance costs.

Bypass Valve Allows unfiltered oil to bypass the contaminated element once the opening pressure has been reached, a differential pressure of 6 + 0,5 bar / 87 + 7.25 PSI ∆p is the standard setting. Other settings available upon request. Reverse Flow Valve Allows reverse flow through the filter head without backflushing the element. - Non-Return Valve Prevents draining of the delivery line during element charge. - Multi-Function Valve "Opening pressure 6 +0,5 bar / 87 +7.25 PSI Bypass, reverse flow capability and non-return valve combined in one valve." - Standard Actuating Pressure 5 -0,5 bar / 72.5 -7.25 PSI ∆p Other actuating pressure settings are available upon request Available Indicators Visual - Electrical - Visual-Electrical 24 V DC, 110 V AC, 230 V AC versions Double Visual-Electrical 24 V DC -
