CJC™ Off-line Fine Filter

APPLICATION
The HDU 27/- series of CJC™ Off-line Fine Filters
are used for the maintenance of fluids for power
transmission, lubrication, cooling and quenching.
The HDU 27/27-108 is ideal for removal of particles,
degradation products and water.
FUNCTION
The filter pump draws fluid from the system tank (at
lowest point) and presses it through the filter insert.
From the centre of the insert the fluid flows through
the filter base and returns to the tank.
The pressure drop over the filter - and consequently
the contaminant absorption of the filter insert - is
monitored on the pressure gauge on the filter top.
The filter outlet port is placed in the filter base. The
filtered fluid should be returned to the tank close to
the suction pipe of the main system pump.
Note that the return point preferably should be
non-pressurized. Contact us in case this is not
possible.
THE FILTER PUMP
The filter pump is a gear wheel pump. The electric motor
can be supplied for all standard AC and DC voltages.
FILTER INSERT
The CJC™ Filter Inserts consist of several discs bonded
together. The material is either cellulose or cotton
linters depending on the fluid to be filtered.

FILTRATION ABILITY
.. Particle Removal
All CJC™ Filter Inserts have the following
filtration degree:
- 3 ìm absolute:
98.7% of all solid particles >3 ìm
- 0.8 ìm nominal:
50% of all solid particles >0.8 ìm
are retained in each pass.
The dirt holding capacity is 4-16 litres of
evenly distributed solids.
.. Degradation Products
Oxidation products, resin / sludge, and varnish
are retained by the cellulose material, which
will retain appr. 4-16 kgs of oil degradation
products.
.. Water Removal
The water absorption potential is up to 50%
(i.e. 2,000-8,000 mL H20) of the total contaminant
holding capacity.
