What we need to spec up your hydraulic filter requirements.
When looking to identify a filter housing for your specific problem we need to know a little bit about what you are trying to achieve and where in your hydraulic circuit you need to fit it. To do this we require a few key pieces of information to ensure correct fit and operation for you. That being:
Port Sizes. What size pipe-work are you fitting the housing into? In many cases this is a BSP measurement.
Operating Pressure. Is the filter operating as a return line, tank top return, pressure or suction filter, or is it simply an in-tank suction strainer?
Flow rate. What is the flow of the hydraulic oil in litres per minute?
Micron. It is important to get the micron rating correct to ensure that you are protecting delicate parts of your hydraulic system further along the flow route from damaging wear particles.
With this information we can then source and supply the correct filter unit. Contact us on 01902 491118 with your hydraulic filter enquiries or contact us via our website Online Enquiry Form.
We can also offer a range of replacement filter elements and housing indicators to help keep you informed when your filters require changing.

Working pressures range from 140 to 420 bar and static pressures from 310 to 830 bar.
Donaldson Duramax ®, well known as the highest rated medium pressure filters available, are most often used in return line positions. As spin-ons, they are particularly well-suited for the duplex circuits. Donaldson Synteq ® and cellulose media are available. Duramax working pressures range from 25 to 70 bar and static pressures from 55 to 140 bar.
Low pressure filters are the most commonly used type of filters in hydraulic circuits, used most often as return line filters in applications with working pressures up to 10 bar and static pressure up to 20 bar.
An expanded line of accessories for hydraulic lines and reservoirs is also available. Finish off your hydraulic circuit with filter service indicators, pressure gauges, test point assemblies, valves, flanges, reservoir level gauges, sight glasses, a variety of tank and filter breathers, caps vents, plugs, strainers, diffusers, magnets and more.
Donaldson is proud to offer a broad selection of hydraulic replacement cartridges and spin-ons to the aftermarket via its distributors. Choose from our many different filter media to find exactly the right filter to help you meet the cleanliness requirements for your hydraulic system.
