CJC Fine Filter
27/27/AL
APPLICATION
Removal of particles, oil degradation products and
water from oil, as well as neutralisation of acids - the
CJC Fine Filter 27/27/AL is used for the maintenance
of a various number of oils and fluids. Typical
applications in industry and power industry are, e.g.:
• hydraulic oil
(presses, test benches, cranes etc.)
• lubrication oil
(bearings, gears, engines, turbines etc.)
• HFD fluids / phosphoric acid ester
(control systems etc.)
• insulating oil
• tap changer oil
• fuel, diesel
(engines, storage tanks)
• aqueous fluids and emulsions
• flame proof fluids
OFFLINE-FILTRATION
CJC Fine Filters are installed offline - in addition to
the inline filters - because only with an offline filtration
is it possible to filter to a range of 1 µm (nominal).
Because only with an offline filtration the fluid flow
rate can be optimally adjusted. The oil can flow slowly
through the filter insert so that even the smallest
contaminant particles will deposit in the depth of the
filter material.
The CJC Fine Filter has to be connected in a separate
circuit to the system tank. The oil should be drawn
from the system tank (at lowest point) and returned
to the tank near the suction point of the main system
pump.
Note that the return point preferably should be
non-pressurized. Contact us in case this is not
possible.
ADVANTAGES
• continuous fine filtration independent from the
operation of the machine
• protection of the expensive online filter
• optimal adjustment of the flow rate
• constant high oil cleanliness
• no problems with pulsating fluid pressures

FILTRATION ABILITY
CELLULOSE BASED FILTER INSERTS
• Particle Removal
All CJC Filter Inserts have the following
filtration degree:
- 3 µm absolute:
i. e. 98.7 % of all particles >3 µm
- 0.8 µm nominal:
and 50 % of all particles >1 µm
are retained in each pass.
The dirt holding capacity amounts to approx.
2 kg of evenly distributed solids.
• Degradation Product Removal
Oxidation by-products, resin / sludge, and varnish
are retained by the cellulose material.
• Water Removal
The water absorption potential amounts to approx.
1.2 L.
