HDU 38/60-100

CJC™ Offline Fine Filter

CJC™ Product Sheet
APPLICATION

The HDU 38/- series of CJC™ Offline Fine Filters
are used for the maintenance of fluids for quenching,
lubrication and coolant systems. The HDU 38/60-100
is ideal for removal of particles, degradation products
and water, with a very high dirt holding capacity.

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 insert
- is monitored on the pressure gauge on the filter top.
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 and DC motors.

FILTER INSERT

The CJC™ Fine Filter HDU 38/100 PV

The CJC™ Filter Inserts consist of several discs bonded together. The material is wood cellulose.

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 7.5-12.5 litres of
evenly distributed solids.
Degradation Products
Oxidation products, resin/sludge, and varnish
are retained by the cellulose material, which
will retain appr. 13.5-22.5 kgs of oil
degradation products.
Water Removal
The water absorption potential is up to 50%
(i.e. 3750-6250 mL H20) of the total
contaminant holding capacity.
