Our company in a nutshell

Our Business

Today, we have expanded our product portfolio and grown into a worldwide corporation with over 11,000 employees and a direct Donaldson presence in more than 39 countries. Donaldson Membranes (based at Newton-le-Willows) is a leading worldwide manufacturer of Tetratex, a proprietary expanded microporous PTFE (Polytetrafluoroethylene) membrane, manufactured solely by Donaldson Membranes. It is laminated to a variety of base substrates to provide a complete range of filter media for both industrial and technical applications.



Industrial Air Filtration Fabric filters are an intrinsic part of many industrial processes. Whether a filter collecting the actual product being manufactured or a pure environmental emission control measure, there is a clear need to maximise performance to ensure collection rates are high, particulate emissions are low and gas flows are maintained at optimum levels for the process concerned.



Each and every application is different and carries with it a specific set of challenges. A host of factors can influence the performance of any given fabric filter, but the selection of an appropriate filter media is critical. Getting it wrong can restrict production levels, raise filter element replacement and filter maintenance costs and cause all manner of environmental concerns for local authorities and neighbours alike.



Technical Products Donaldson unique Tetratex® ePTFE filter media protects devices and enclosures from temperature and pressure fluctuations, moisture and harmful contaminants. Our wide range of filter media options increases the effectiveness and reliability of micro-environments and can help to extend product life.
