By pass oil filters
The by-pass oil filter type ATM are designed to clean oil in multiple satges. At the first stage there is an absorption filter process through a fibrous layer of special composition to trap the "soft contaminants" which are then coagulated on the surface of the fibres. Soft contaminants are decomposed oil components, water condensed in tanks and its emulsion products, external organic contaminants and oil-oxidation products. The filter caontains additional and effectve absorbents to function as moisture separators, as well as to hold light destillates (fuel) in the case of engine oils, while trapping solid particles of size of 3-5 µm. It has excellent dirt holding capacity.
Available for engines, hydraulic systems, gears and transformers. Upon reqest these filters are also available with pump; in portable or stationary design; electric or pneumetic.
