Product Description:

STAUFF SFA series Medium Pressure Filters are designed for in-line hydraulic applications with a maximum operating pressure of 160 bar / 2320 PSI. Used together with STAUFF SE series Filter Elements, 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.

Technical Data:

Options and Accessories:

Valve

• 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 change.
• 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.

Clogging Indicator

• 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)
