HDU 427/- are Fine Filters for offline oil filtration with 4 stays/stacks of filter inserts fitted inside a single filter housing. They are used to maintain clean oils and fluids in 2 & 4 stroke diesel engines, hydraulic power transmission, 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.
The HDU 427/- series is ideal for:
- Marine diesel engine lubrication
- Lubrication systems (e.g., roll-neck bearings, screw down gears, etc.)
- Quench works
- and similar industrial and marine applications
Used for quench oil, the filter removes:
- Dust, metal particles, rust
- Ingressed water
- Oxidation deposits
- Cracking deposits (resins)
The HDU 427/- series is available in sizes 427/54, 427/81 and 427/108, using 4 stacks, with each containing 2, 3 or 4 CJC™ Filter Inserts.
CJC™ Oil Maintenance Systems are available in a range of design configurations including pre-heaters, drip pans, tanks, and control boxes.
