APPLICATION
The CJC™ HDU 15/12 Compact Offline Oil Filter is
used for maintaining clean oil in (power) transmission,
hydraulic and lubrication circuits. The HDU 15/12 is
ideal for removal of particles, oil degradation products
and water in applications such as:
.. Mobile Hydraulic Equipment
.. Packaging Machines
.. Compact Hydraulic Systems
FUNCTION
The filter pump draws fluid from the system tank (at lowest
point) and pumps it through the filter insert. From the
centre of the insert the fluid flows through the filter house
and returns to the tank.
The pressure drop across the filter insert - and consequently
the contaminant absorption of the filter insert - is
monitored on the pressure gauge on the filter base.
The filter outlet port is placed on the front of the filter.
The filtered fluid should be returned to the tank close to
the suction pipe of the main system pump.
Note that the return point should be non-pressurized.
Contact us in case this is not possible.
THE FILTER PUMP
The filter pump is a gear pump. The electric motor can be
supplied as AC or DC motors. IP Class: IP 55
FILTER INSERT
The CJC™ Filter Inserts consist of several discs bonded
together. Depending on the fluid to be filtered, the material
is either cellulose or cotton linters.

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 0.75 litres of evenly
distributed solids.
.. Degradation Products
Oxidation products, resin / sludge, and varnish are
retained by the cellulose material, which will retain
appr. 0.5 kg of oil degradation products.
.. Water Removal
The water absorption potential is up to 50%
(i.e. 375 mL H20) of the total contaminant
holding capacity.
