Compressed Air Filter for Pneumatic Systems

The Festo LF-3/4-D-5M-MAXI-A-NPT compressed air filter removes particulates down to 5 µm with a fully automatic condensate drain. It handles a standard nominal flow rate of 3600 l/min at operating pressures from 2 bar to 12 bar. The die-cast zinc housing with metal bowl guard suits industrial environments requiring moderate corrosion resistance.

Vertical Mounting with NPT Connections

Installation requires vertical mounting orientation and 3/4 NPT threaded connections on both ports. The polycarbonate bowl with metal guard allows visual monitoring while protecting against impact. Ensure thread sealant compatible with compressed air systems is used to prevent leaks at the NPT fittings.

Check Pressure Range and Filtration Grade

Verify your system operates within the 2 bar to 12 bar pressure range and that 5 µm filtration meets your air quality requirements. Confirm ambient and medium temperatures stay between 5 °C and 60 °C. The 80 ml condensate capacity suits typical duty cycles but high humidity may require more frequent monitoring.

Questions about this item

How can I confirm the filter is operating correctly once installed?

Verify that the pressure drop across the filter stays within the expected range for a 3600 l/min nominal flow rate and that the fully automatic condensate drain cycles without manual intervention.

What components are included in the box and what must be sourced separately?

The box contains one Festo LF-3/4-D-5M-MAXI-A-NPT filter assembly with metal bowl guard and PE filter element; NPT pipe fittings, tubing and mounting brackets are not included.

Which specification should guide my choice between available versions of this filter?

Select based on the required filtration grade — this model provides 5 µm filtration — and ensure your system operates between 2 bar and 12 bar with 3/4 NPT connections.
