Description
The Festo LFR-1/4-D-MINI-A is a compact, high-efficiency filter regulator designed for precision air preparation in pneumatic systems. Engineered for space-constrained installations, this miniature unit combines air filtration and pressure regulation into one durable, easy-to-mount module.
It features a 40 µm filter, a fully automatic condensate drain, and an integrated analog pressure gauge. With a flow capacity of up to 1400 l/min, it delivers stable output pressure within a regulation range of 0.5 to 12 bar, while maintaining low hysteresis. The metal bowl guard ensures added protection in demanding environments.
Constructed from die-cast zinc and PC, this RoHS-compliant unit is suitable for use with compressed air and inert gases, conforming to ISO 8573-1:2010 [7:8:4] air purity standards.
