STF Tank Top Mounted Return Filters: The Ideal Choice for Restricted Aluminum Applications

The STF Tank top mounted return filters from Parker, comes equipped with a magnetic column and a bypass with low hysteresis for efficient pre-filtration. Employing the "In-to-Out" filtration principle, the filter prevents contaminated oil from seeping back into the system. Crafted with a cast iron filter head assembly, this filter is well-suited for marine applications that require non-aluminum materials. With a filter head that boasts multiple ports, it can easily handle flow rates of up to 500 liters per minute at 10 bar working pressure, making it a convenient and effective option for integrating return line filtration with power packs. Additionally, standard airtight diffusers are available as an optional feature to prevent air ingress in the return line.

The STF series offer several advantages for marine applications where the use of aluminum is restricted, featuring:

  • Cast iron filter head assembly
  • LEIF® elements
  • Magnetic pre-filtration
  • In-to-Out filtration - contaminated oil cannot leak back into the system
  • Muliple port configuration
  • Full flow bypass with low hysteresis
  • Standard or customised funnel
