The Multi Direct Mounting system on UM models provides a total of 12 mounting points (four on the left, right and bottom sides) enabling direct compatibility with TM31 and QP31 compressors. Each mounting point has an M10 x 1.5 mm threaded hole, providing excellent flexibility in engine mounting and bracket design.
A low-side service valve is fitted to the rear cap, including a high-pressure relief valve.
An oil return fitting – 7/16-20 UNF male flare (Part No. 42203-000160) – is fitted on top of the compressor. It has a unique flow design suited to the Unicla oil separator (Part No. OS000030) and is interchangeable with the low-side service valve.
Consistent M12 x 1.0 mm access port size. Easy interchange of blanking plugs, service valves, oil return and pressure switch fittings.
Porting for horizontal or vertical hose connections are standard, achieved by heavy duty blanking plates installed on outlets that are not in use. A range of standard hose port manifolds is available.
