HDU 27/27-108 CJC™ Product Sheet PSST1001-UK 09.04.2008 CJC™ Off-line Fine Filter Page 1/2 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. OPTIONS .. Preheater .. Tank .. Drip pan .. Control box • Pressure switch 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.
