Hydac_Filter_RFM

RFM Series
In-Tank Return Line Filters
145 PSI • Up to 224 GPM

Features

  • The compact and lightweight design make RFM filters especially suitable for mobile applications.
  • RFM filters are constructed of polyamide plastic housing and lid.
  • RFM 90/150/210/270 drop replacement for "Tank Topper" filters.
  • Aluminum alloy is water tolerant - anodization is not required for water based fluids (HWBF).
  • The filter bowl on models 75 - 270 also serves as a contamination basket - removed to change element.
  • Models 30, 330, 500, 661, and 851 have filter elements equipped with separate, reusable contamination baskets.
  • Cavities for clogging indicators are standard.
