Strong and durable, Donaldson spin-on, cartridge, and in-tank assemblies provide industry-leading protection to help keep your hydraulic circuits running smoothly and your heavy-duty equipment doing its job.

FIS2 In-Tank

FIS2 in-tank filters are economical, durable, and space-saving units. FIS2 filters, featuring a die-cast aluminium head and a bowless design,  designed to handle heavy-duty applications. The head (and the inlet) sit above the tank, while the housing remains inside the tank, offering design-in flexibility.

Features

  • Strong, durable, heavy-duty aluminium die-cast head
  • Fluorocarbon seals are available
  • One head for multiple different element sizes
  • Bypass valve built into the replacement element
  • Variety of indicator types and bypass options

Benefits

  • Inside-out flow limits aeration
  • Contaminants stay with the element when servicing
  • Flexible mounting configurations allow for better sealing and stability
  • Reverse compatible retrofit on existing tanks

Applications

  • Cooling circuits; Fluid Conditioning Systems; Lube Oil Systems; Process Systems; Return lines; Side Loop Systems

FISB

Donaldson FISB in-tank filter assemblies are ideal for mobile and industrial power unit hydraulic applications where the breather integrated into the filter head can save space to yield a compact solution.

Features

  • High-performance media filter elements deliver lower operating ISO Codes with high efficiency particulate removal and retention efficiency.
  • The top-loading FISB housing provides easy and clean access during element service — no special tools required.
  • Adding a breather to the FISB assembly is easy because the breather can be incorporated directly into the filter housing. Utilizing exclusive T.R.A.P. technology, the breather removes both airborne moisture as well as 97% of particulate 3 micron and larger. 

Benefits

  • Inside-out flow limits aeration
  • Contaminants stay with the element when servicing

Applications

  • Cooling circuits; Fluid Conditioning Systems; Lube Oil Systems; Process Systems; Return lines; Side Loop Systems

Duramax HMK 04/05

HMK04 and HMK05 Duramax® spin-on filters are perfect for high-flow applications, featuring a heavy-duty steel body and die-cast top plate for added strength. A special head-to-canister o-ring seal prevents leakage.

Features

  • Strong, durable heavy-duty steel body and die-cast top plate construction
  • Special head-to-canister O-ring seal prevents leakage
  • Nitrile seals are standard, but fluorocarbon seals are available
  • Variety of indicator types and bypass options

Benefits

  • Proven Duramax filters deliver dependable performance 
  • Double filter heads are available to deliver twice the flow capability and contaminant capacity

Applications

  • Case drains; Cooling circuits; Fuel transfer; Hydrostatic charge pumps; Lube oil systems; Power transmissions; Return lines; Side loop systems; Fluid conditioning systems
