Selection Guide

LFR, LFRS

The filter regulators LR and LRS are a combination of coarse filter and pressure regulator in one unit.
The regulators can be selected in two pressure regulation ranges: with 7 bar and 12 bar control pressure. There are two pressure gauge connections to choose from, depending on the flow direction.
The rotary knob is lockable and can be protected against manipulation with a protective cap and a padlock. The alternative is the integrated E11 pressure gauge lock with key. It is also available with manual or automatic condensate drain. The LFR of the D series is available in four sizes with a standard nominal flow rate of 400 to a maximum of 10,000 l/min.
