HDU 727/108

CJC™ Offline Fine Filter

CJC™ Product Sheet
APPLICATION

The CJC™ HDU 727/108 Offline Fine Filter is used
for the maintenance of fluids for steel pressing systems, power transmission, lubrication, cooling
and quenching.
The HDU 727/108 is ideal for removal of degradation
products, particles and water.

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 base and returns to the tank.
The pressure drop across the filter insert - and consequently the contaminant absorption of the filter inserts
- is monitored on the pressure gauge on the filter housing.
The filter outlet port is placed in the filter base. The
filtered fluid is to 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 if this is not possible.

THE FILTER PUMP

The filter pump is a gear wheel pump. The electric motor can be supplied as standard AC motors.

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.

Particle Removal
All CJC™ Filter Inserts have the following
filtration degree:
- 3 μm absolute:
98.7% of all solid particles >3 μm
- 0.8 μm nominal:
50% of all solid particles >0.8 μm
are retained in each pass.
The dirt holding capacity is 112 L of
evenly distributed solids.
Degradation Products
Oxidation products, resin / sludge, and varnish
are retained by the cellulose material, which
will retain appr. 112 kgs of oil degradation
products.
Water Removal
The water absorption potential is up to 50%
(i.e. 56,000 mL H20) of the total contaminant
holding capacity.
