Pressure filter is designed for circulating oil lubricating systems for gear units of medium and high power with the ability to work in the most severe conditions. Filter is installed on the pressure line in any position. The direction of oil flow is printed on its body. The filter cartridge is made of high strength wire cloth. Periodically it is necessary to unscrew the filter cup, remove the cartridge and wash in gasoline. The cleaning period depends on the intensity of work and the degree of purity of the oil.
