Compressed Air/Gas: Housings

With over 30 years of expertise in compressed air filtration and separation, Donaldson Compressed Air & Process delivers the most efficient and cost-effective filtration housings engineered to provide lower pressure drop, longer filter life, quick and easy element change-outs and more predictable maintenance.

Ultra-Filter (DF) Standard/Superplus
Compressed Air Filters

Donaldson Ultra-Filter (DF) filters
are designed for high quality filtration of compressed air or gas in a wide of applications. The total filter design concept of the filter combines high performance, greater efficiency, ease of use, flexibility, and safety. The high performance is achieved by the flow-optimized filter design, paired with innovative filtration technology; this reduces pressure loss by 50% compared to conventional filters. The unique bayonet lock ensures that the filter cannot be opened under pressure for increased safety. You will find greater energy savings are achieved by the timely replacement of a used filter element. This is determined by the Economizer that continuously measures the different pressures. An integrated microprocessor evaluates the measurement data and compares the higher energy costs caused by pressure loss with the costs of a new filter element. The DF series is available in nine sizes, six filter elements types, and perfectly meeting all industrial air purification application requirements.

Three Stage Filters (DF-Three Series)
Donaldson Three-Stage Filters are designed for the removal of oil aerosols, oil vapors, and solid particles from compressed air and gases with a single filter element. The filter element combines three purification stages in one filter, thus reducing the installation space required by up to 60%. The DF-Three reliably produces Class 1 quality compressed air according to ISO8573-1:2010 for flows up to 65 scfm.

Cyclone Water Separators
Donaldson DF-C Cyclone Separators deliver high separation efficiency at low pressure drop through an optimal flow-path design. Available in six different sizes with a flow range from 70 to 647 scfm at 100 psig.

Donaldson AG-Z Cyclone Water Separators are three-piece aluminum housing that includes swirl vanes allowing for efficient liquid removal with low pressure drop.

HD High Pressure Filters
Donaldson HD High Pressure filter housings are designed for the purification of compressed air and gases in an industrial operation. The housings made out of two parts offer, due to an optimized construction, low differential pressure at high flow rates. A multitude of housings with different connections allows you to match your specific needs to any application. The HD has 8 different housing sizes available ranging from ¼” to 2” and pressure rating from 400 psig to 5,800 psig.

SG Compressed Air Filter Housings
Donaldson SG steel filter housings are designed with all of the features required to make these the most efficient and cost effective filters for your compressed air system. The flanged housings offer low pressure drop through optimal flow-path design. The SG standard filter housings comes with an Econometer differential pressure gauge and pneumatic drain and are available with an optional Economizer differential pressure gauge and Ultramat zero air-loss condensate drain.

AG Compressed Air Filter Housing
Donaldson AG Standard and Superplus aluminum housings include our Econometer differential pressure gauge and external float drain valve for coalescing applications. Available in several sizes ranging from 864-1728 scfm of air. AG housings and elements are available in silicon-free versions.
