Combining effective filtration with a cast steel filter, the STF series of tank top mounted return filters from Parker Hannifin are designed for marine and industrial applications were the use of aluminium is restricted in accordance to the latest regulations.

Featuring ‘In-to-Out’ filtration, the STF series filters ensure contaminated oil cannot leak back into the system. The STF series filters are capable of handling flow capacities of up to 500 l/min at 10 bar working pressure, making them suitable for severe return line applications while reducing downtime due to filter failures.

The magnet column of the STF series filters provides pre-filtration which improves fluid cleanliness levels and extends element lifetime by more than 20%. An effective flow bypass with low hysteresis reduces the bypass period and ensures only a small part of the total flow is bypassing the element, offering improved protection for the system. Additionally, multiple ports in the STF series filter head make it easy to integrate return line filtration into power packs, reducing cost and space.

The STF series filters are compatible with Parker’s LEIF elements, which minimise waste and therefore reduce the environmental impact of a system. The Parker’s LEIF elements provide filtration in line with ISO 14001.

Applications for the STF Series of tank top mounted return filters from Parker Hannifin include marine power packs, steel mills, mining equipment, and drilling machinery and due to ATEX certification, the STF filter can be used in potentially explosive atmospheres.
