HDU multistay


HDU Multistay are Fine Filters for offline oil filtration with 2, 3 or more HDU 27/- series filter housings installed in parallel, used for maintenance of fluids in large hydraulic power transmission, lubrication, cooling and quenching oil 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. 

HDU Multistay filters are available in sizes HDU 2 x 27/- , HDU 3 x 27/-, and more stays, depending on the required oil capacity.

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

The HDU Multistay series is ideal for:

  • Marine diesel engine lubrication 
  • Lubrication systems (e.g., gas turbines, roll-neck bearings etc) 
  • Industrial gears for the steel and paper industries  
  • Large hydraulic systems 
  • Quench works
