HDU 27/-  is a fine filter for offline oil filtration for medium to large hydraulic power transmissions, lubrication, cooling and quenching systems.

The filter is a 3-micron absolute filter with a high dirt-holding capacity and a cellulose-based filter insert that removes particles, retains oil degradation products (oxidation resin/sludge, varnish), and absorbs dissolved/emulsified and free water from oil.
Special inserts, which do not absorb water, are available on request.

The HDU 27/- series is available in sizes 27/27, 27/54, 27/81 and 27/108, using from 1-4 CJC™ Filter Inserts fitted in the same filter housing.

CJC™ Oil Maintenance Systems are available in a range of design configurations including pre-heaters, drip pans, tanks, control boxes, coalescers.

The HDU 27/- series is ideal for:

Hydraulic systems  (e.g., test benches, power packs for cranes, presses etc.),
Lubrication systems (e.g., for bearings, gears etc.),
Marine diesel engine lubrication,
Quench works,
and similar industrial and marine applications.
