Festo Series MS Filter Regulator, 40μm grade of filtration, 0.50 bar to 12 bar Pressure Regulation Range - MS4-LFR-1/4-D7-E-R-M-VS, Numeric Part Number: 8232855

This filter regulator conditions compressed Air by separating condensate and maintaining a stable reduced outlet pressure for pneumatic systems. It is designed for vertical mounting with a rotary knob actuator and is suitable for compressed Air and inert gases meeting ISO 8573-1:2010 Air quality classes. Operating and media temperatures range from -10°C to 60°C and the unit is specified for moderate corrosion environments.

Features and Benefits:

• 40 μm filtration delivering greater than 75% condensate separation
• 0.5 to 12 bar pressure regulation enabling precise output control
• 1500 L/min standard flow supporting high-demand installations
• Manual condensate drain with rotating action for simple servicing
• G1/4 pneumatic ports with 1/4 in gauge port thread for fittings

Applications

• Suitable for supplying actuators requiring clean compressed Air
• Ideal for control panels using inert gas supply lines
• Used with production machines needing constant output pressure
• Can be used for plant Air networks requiring high flow rates
• Suitable for food-related systems per supplementary material notes

What is the allowable operating pressure range?

The unit operates between 0.08 MPa and 1.4 MPa, which corresponds to 0.8 bar … 14 bar.

What materials compose the main wetted parts?

The housing and sub-base are die-cast aluminium, the bowl is Makrolon® polycarbonate and Seals are NBR.

How is pressure adjustment secured against accidental change?

The control uses a rotary knob with detent to lock the chosen setting and limit hysteresis to 0.025 MPa.

What mounting orientation is required for reliable function?

It is designed for vertical mounting within ±5° to maintain separation performance.

What Air purity is expected at the output?

Output Air meets ISO 8573-1:2010 class 7:4:4 under the specified conditions.
