DONALDSON | Filter Head Dual DN40 (1 1/2") SAE Port

  • Clean Solutions filter heads can handle up to 125gpm / 473 lpm.
  • They feature robust, aluminium construction with steel inserts to minimise metal-to-metal galling between the head and the filter, even when used with diesel fuel.
  • Viton® seals are compatible with the widest range of fluids and maintain integrity in cold weather.
  • The head is leak-free, ensuring that fluids stay in and contaminants stay out.  
  • For maximum cleanliness, use Clean Solutions heads with Clean Solutions filters.

  • When a dual head is used, always change both filters, using identical filter models for both
  • When adding water absorbers, connect two dual heads in series with particulate filters primary and water absorbing filters secondary
  • Isolate filter and relieve pressure prior to servicing
  • Loosen filter by rotating counter-clockwise using strap wrench
  • Install clean filter by rotating clockwise, tighten 1/2 turn after filter seats in gasket - Use strap wrench if needed, but do not over tighten
  • Dispose of used filters appropriately
