Selection Guide

Service unit combinations with lubricator, FRC

The FRC service units of the D series in metal are a combination of a filter regulator with a downstream lubricator. The FRC combinations can be selected in two pressure regulation ranges with 7 bar and 12 bar control pressure as well as with 40 µm and 5 µm coarse filters. 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 FRC combinations of the D series are available in four sizes with a standard nominal flow rate from 160 up to maximum 8,000 L/min.

Service unit combinations without lubricator, LFRS

The LFR and LFRS service units of the D series in metal are pre-assembled combinations of a filter regulator with further functional elements. Depending on the configuration, these are manually operated pressurization and exhaust valves, branch modules, electrically operated pressurization and exhaust valves and soft start valves. The LFR combinations are designed for control pressures up to 12 bar and are available with a 40 µm coarse filter. 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 combinations of the D series are available in three sizes with a standard nominal flow rate from 720 up to maximum 9,400 L/min.
