When you need filter housings, filter heads, replacement cartridges, spin-ons (e.g. Donaldson Duramax™) or hydraulic accessories, turn to Donaldson.

High Pressure Filters Donaldson heavy-duty high-pressure filters sit behind pumps and other prime movers to protect critical hydraulic components such as cylinders, motors and valves. All contain our SYNTEQ® synthetic filter media, specially developed by Donaldson for high efficiency liquid filtration. Working pressures range from 2000 psi up to 6090 psi; static pressures from 4500 psi up to 12000 psi.

Medium Pressure Filters Donaldson DURAMAX®, well-known as the highest rated spin-on style filters available, are most often used in return-line positions. As spin-ons, they are particularly well-suited for duplex circuits. Donaldson Synteq® and cellulose media available. DURAMAX working pressures range from 350 psi up to 1000 psi; static pressures from 800 psi up to 2000 psi.

Low Pressure Filters Low pressure filters are the most commonly used type of filter in hydraulic circuits, used as return line filters in applications with typcial working pressures up to 150 psi and static pressure up to 300 psi. Donaldson offers flow/pressure combinations to fit most applications. Continuous filtrations of bulk fluids through dedicated off-line circuits or kidney loops helps keep fuel, oil and lubricants clean.
