Festo Filter Regulator, Polycarbonate Bowl Construction, Compressed Air Medium - MS4-LFR-1/4-D6-ERV-AS

When the job calls for consistent system pressure and minimal air wastage, go for this filter regulator from Festo. It combines the airflow-stabilising features of a regulator with the contaminant-reduction function of a filter. That means you're getting a two-in-one device that boosts the performance of your pneumatic application. The unit comes with a 40μm-grade filter built in, so it sifts out tiny particles like pipe sinter and rust, as well as condensate from your compressed air medium. Thanks to low hysteresis, integrated pressure compensation and secondary safety exhaust, you can count on this device to take care of pressure build-ups too.

Features & Benefits

• Hardwearing die-cast aluminium housing and polycarbonate bowl for durability in challenging settings

• Lock-on rotary knob lets you secure it in place to prevent tampering

• Simplifies piping and installation needs, thanks to its two-in-one functionality

Applications

• Food and drinks packaging

• Medical equipment

• Aerospace engineering

• Pharmaceutical production

What's the benefit of this product's G1/4 threaded connection?

The industry-standard G1/4 thread on this filter regulator's connection ports makes it a piece of cake to connect up your pneumatic lines.
