HDU 427/54-108

Product catalog summary

Application
The HDU 427/- series of CJC® Off-line Fine Filters are designed for maintaining fluids used in power transmission, lubrication, cooling, and quenching. The HDU 427/54-108 model is particularly effective in removing degradation products, particles, and water from these fluids.

Function
The filter system operates by drawing fluid from the system tank and pressing it through the filter insert. The filtered fluid is then returned to the tank, ideally near the suction pipe of the main system pump. The system includes a pressure gauge to monitor the pressure drop and contaminant absorption.

Filter Pump
The filter pump is a gear wheel type, compatible with standard AC and DC voltages.

Filter Insert
The inserts are made of bonded discs of cellulose or cotton linters, depending on the fluid type.

Options
Available options include a preheater, tank, drip pan, control box, and pressure switch.

Filtration Ability

Particle Removal: Filters 98.7% of particles >3 µm and 50% of particles >0.8 µm.
Degradation Products: Retains approximately 32-64 kg of oil degradation products.
Water Removal: Absorbs up to 50% of its total contaminant holding capacity in water.

APPLICATION The HDU 427/- series of CJC® Off-line Fine Filters are used for the maintenance of fluids for power transmission, lubrication, cooling and quenching. The HDU 427/54-108 is ideal for removal of degradation products, particles, and water. FUNCTION The filter pump draws fluid from the system tank (at lowest point) and presses it through the filter insert. From the centre of the inserts the fluid flow through the filter base and returns to the tank. The pressure drop over the filter - and consequently the contaminant absorption of the filter inserts - are monitored on the pressure gauge on the filter housing. 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 • Pressure switch • Particle Removal All CJC® Filter Inserts have the following filtration degree: - 3 yum absolute: 98.7% of all solid particles >3 yum - 0.8 um nominal: 50% of all solid particles >0.8 yum are retained in each pass. The dirt holding capacity is 32-64 litres of evenly distributed solids. • Degradation Products Oxidation products, resin / sludge, and varnish are retained by the cellulose material, which will retain appr. 32-64 kgs of oil degradation products. • Water Removal The water absorption potential is up to 50% (i.e. 16,000-32,000 mL H20) of the total contaminant holding capacity. HDU 427/54-108 CJC® Offline Fine Filter TECHNICAL DATA *) The standard filters are designed for a max. temp. of 80"C / 176"F. Other conditions, please contact us.
