TFRC In-Tank Return Line Filter Assemblies

Donaldson Hy-Pro TFRC in-tank filter assemblies are ideal for particulate contamination removal in small hydraulic power units and mobile equipment where a tank breather is not integrated into the filter head.

Max Operating Flow: 40 gpm (151 lpm)

Max Operating Pressure: 150 psi (10 bar)

Go beyond industry standard_TFRC

Go beyond industry standard.

Advanced DFE rated filter elements deliver lower operating ISO Codes with high efficiency particulate removal and retention efficiency. With integral element bypasses and a range of media options down to β3[c] > 4000 + water absorption, you get the perfect element for your application, every time.


Minimize the mess.

The top loading TFRC housing provides easy and clean access during element service – no slippery spin-ons to handle. A bolt on aluminum cover allows for quick element changes with common hand tools. The unique element design eliminates the need for a hold down spring or bypass to be installed during servicing, just drop in the element and bolt on the cover.

Inside to out flow_TFRC

Inside to out flow.

The TFRC housings utilizes an inside-to-outside element flow, meaning all the dirt captured by the element stays in the element during service. They don’t release dirt back into the system with traditional outside-to-in element designs that re-contaminate hydraulic tanks during filter changes.


Dirt removal’s never been so easy.

Packed with features including; easy service aluminum cover, industry standard 2-bolt and 4-bolt mounting patterns, integral element holddown/ removal handle (no-spring), and integral bypass (new bypass with every element change).

Eliminate aeration_TFRC

Eliminate aeration.

Smaller reservoirs, high return flow and high velocity through outside-to-in flow elements add up to tank turbulence and reservoir aeration with poor air release. TFRC prevents aeration by diffusing return flow and creating laminar conditions inside the hydraulic tank.
