SFA Medium Pressure Filters (Inline)

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.

Options and Accessories

Valves

• 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.
• 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 Indicators

• 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 VDC, 110 VAC, 230 VAC versions)
  • Double Visual-electrical (24 V DC)
