Compressed Air Elements

We carry the entire range of Donaldson DF Series Filter Elements. Use these for excellent Compressed Air Purification in a wide range of air, technical gas and tank ventilation filtration applications.
Elements are available in models that resist corrosion, resist high temperatures, and meet ISO standards.
The offering includes the B, V, M, S and A series of filters in a range of sizes. See the table below to determine which filter is the right choice for your application.

Donaldson has discontinued the P-series. We recommend using the V-series or the B-series instead, depending on your specific application. Please contact us at 1-800-726-5515 for technical assistance with selecting the right filter.
