High performance hydraulic tank filters

Called the PT Series, the filters feature an integrated construction and are designed to provide long service life. Offering a nominal flow capacity of up to 400 l/min, while working at pressures of up to 10bar, the PT Series filters feature an in to out filtration system, widely used by Parker. This method uses pressure to extrude the return oil through the filter while retaining contamination. As a result, only clean oil enters back into the reservoir and all contamination is held within the filter element, increasing overall system performance and service life. The filter element and filter housing cover are integrated to form one consumable part, allowing for an extremely compact construction that is simple to fit, particularly in applications where space is at a premium. The aluminium filter housing remains re-usable part bolted on to the hydraulic reservoir. For direct integration in plastic tanks the complete element can be integrated as a screw-in part, eliminating the need for the tank top mounted filter head. The complete element unit can simply be rotated and pulled out of the plastic reservoir or tank top mounted filter head, making filter changeover fast and easy, while eliminating the need to reinstall loose components and reducing machine downtime to an absolute minimum. In addition, this construction prevents dirty oil from dropping back into the tank as all contaminants are retained within the filter media, increasing hydraulic system performance still further. The new PT series filters feature seals that cover the space between the filter element and the filter housing, offering maximum protection against oil leakage. When used in conjunction with Parker's standard and custom built reservoirs and airtight funnels, air ingress is eliminated creating an optimal oil flow path, resulting in improved system efficiency and reduced energy consumption.
