Duplex Filters::...

These filters are designed at operating pressure of 25, 100 & 160 bar. They are fitted when continuous operation is required & any interruption in flow for filter maintenance needs to be avoided. They are suitable for in-line installation.

The filters are suitable for all mineral oils, hydraulic oils and lubricating oils.

Cleanable Filter Media :

Wire Mesh G (Nominal Filtration) (From 5 to 1500 Micron) Wire mesh G is a surface-filter material made of stainless steel wire in plain/twill weave. It is Supplied in the filter grade of 5 micron to 1500 micron ratings. This economical and regenerative material can be cleaned properly by washing it with solvents and blowing it throughly with compressed air. (Refer>Cleaning Filter Elements) Non-Cleanable Filter Media (Disposable Type) Hydroclean H (Absolute Filtration) (1,3,6,10 & 20 Micron) A non-regenerative, micro-fine deep-filter material is used for as low as 1 micron, filtration. It is a combination of polyester matting and other inorganic fibre with a multitude of fine pores. The special deposition surface created by this combination ensures good dirt absorption and excellent throughflow. Water Absorbant W (Absolute filtration) (1,3,6,10 & 20 Micron) A non-regenerative, micro-fine depth filter material is used in combination with Hydroclean-H media. The media layer has scattered granulates of water absorbing substances. The required filtration grade is achieved by the hydroclean-H media which is fitted behind this media layer.
Paper-P (Nominal filtration) (5,10,15 & 25 Micron) A tried and tested lint Free Material is made swell-resistant by impregnation with phenol formaldehyde. The cellulose-fibre material has good throughflow and dirt absorption characteristics but, limited fineness.
Non-woven N (Nominal filtration) (25,40 & 60 Micron) Non-woven is surface filtration media is made up of polyethylene wrapped polyester fibres. This media is a cheap alternative for mesh media. It is recommended for coolant, water and coarse filtration.

Cleaning Filter Elements ::...

• Loose contamination can be washed from the surface of the filter element by agitating the element in a suitable solvent. Only Stainless Steel Wire-mesh type elements should be cleaned, in this manner.
• Lightly brush the element to remove the stubborn particles. To prevent damage to the high quality wire mesh do not use a hard or a sharp cornered brush. This should be effective for larger particles and be suitable for elements of 25 micron and above. For finer elements, including metal felt, and where there is heavy or dense contamination, ultrasonic cleaning may be required.
• After washing, an air line should be used to dry the element and to blow loose particles from the elements. Introduce the airline into the centre tube, so that the air passes from inside to the outside of the elements. Large particles (40 microns and greater) can be removed from the elements without washing by this mean.
• After cleaning, store the element in a plastic bag and seal the bag to keep it clean until next requirement.
• Solvents: Trichloro Ethylene or Petrol or Kerosene
