Festo Series MS Filter Regulator, 0.50 to 12 bar Pressure regulation range, 40μm filtration size - MS4-LFR-1/8-D7-E-R-M-VS, Numeric Part Number: 8232859

This filter regulator provides pressure control and particulate removal for compressed Air systems, delivering a consistent downstream pressure while removing condensate and solids. Designed for vertical mounting, it is suitable for use with compressed Air and inert gases within typical industrial ambient and media temperature limits. Materials include a die-cast aluminium housing with a polycarbonate bowl and NBR Seals to suit moderate corrosion environments and compliance with ISO 8573-1:2010 Air treatment classifications.

Features and Benefits:

• 900 L/min standard flow rate for high-throughput applications
• 0.5 to 12 bar regulation range for precise pressure control
• 40 μm filtration size to remove fine particulates from Air
• Manual drain design enables simple condensate removal
• G1/8 pneumatic ports provide standard G thread connectivity

Applications

• Suitable for pneumatic tool feed lines in production cells
• Used with Air actuators requiring stable output pressure
• Ideal for compressed Air preparation in assembly machinery
• Can be used for inert gas pressure conditioning in laboratories

What materials contact the medium and affect chemical compatibility?

The medium contacts a die-cast aluminium housing, Makrolon® polycarbonate bowl, NBR membrane and seals, and a POM separating plate which determine compatibility.

How does the unit handle condensate separation and capacity?

Condensate separation exceeds 75% with a maximum condensate bowl volume of 19 ml and a rotating manual drain for discharge.

What mounting orientation and installation interfaces are required?

It is intended for vertical mounting within ±5° and connects via G1/8 ports with a 1/8 in pressure gauge port thread standard for gauge fitting.

Which environmental ranges apply to storage and operation?

Storage, ambient and media temperature limits are -10 °C to 60 °C and operating pressure ranges from 0.08 MPa to 1.4 MPa.

What performance tolerance exists for pressure stability?

Maximum pressure hysteresis is 0.025 MPa (0.25 bar), supporting steady regulated output.
