Festo MS4N-LFM-1/4-BUV-DA Fine Filter 1 µm 360 l/min 1/4 NPT

Pneumatic Fine Filter for Food-Industry Compressed

The MS4N-LFM-1/4-BUV-DA is a fiber filter rated at 1 µm with 99.99 % efficiency and a residual oil content of 0.5 mg/m3. It is built for food-industry use with a die-cast aluminum housing and borosilicate fiber element. The unit mounts vertically within a five-degree tolerance and operates between 5 °C and 60 °C. A visual differential-pressure display signals when the element needs attention.

1/4 NPT Ports and 360 l/min Maximum Flow

The filter connects via 1/4 NPT inlet and outlet ports and delivers a maximum standard flow rate of 360 l/min for the specified air quality class. Minimum flow for that class is 54 l/min, and the bowl holds up to 25 ml of condensate before the fully automatic drain activates. Operating pressure spans 2 bar to 12 bar, making it suitable for standard plant-air systems.

Automatic Drain and Metal Bowl Guard

A fully automatic condensate drain removes collected liquid without manual intervention, supporting uninterrupted operation during extended shifts. The integrated metal bowl guard protects the housing against moderate corrosion stress (CRC 2) and mechanical impact. These features maintain consistent filtration performance over long production runs where frequent maintenance stops are impractical.
