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.

Ultrapoly P Particle Filter Element
Donaldson Ultrapoly P prefilter element is designed for removal of solid contaminants in gases. Ultrapoly P utilizes a highly porous sintered polyethylene media for absolute filtration of particles down to 25 μm in size. The primary filtration mechanism of this media is sieving,which captures most particles near the surface allowing for regeneration of the element and reducing operating cost.

Ultraporex B Particle Filter Element
Donaldson Ultraporex B prefilter element is designed for removal of particulate contaminants in gases. Ultraporex B utilize a highly porus sintered media for absolute filtration of particles down to 25 μm in size. Although the Ultraporex B is primarily used as a particulate prefilter, a simple reversal of flow through the element allows the Ultraporex B to be used as an effective course coalescing filter element, removing bulk quantities of water and oil from an air or gas stream.

Ultrac A Activated Carbon Vapor Filter Element
Donaldson Ultrac A adsorption filter element incorporate two stages of filtration. The first stage contains activated carbon for removal of oil, hydrocarbon and odor vapor through adsorption. The second filtration stage consists of binder-free borosilicate depth media, support by microfiber polyamide fleece, for removal of particulate contamination in the air or gas stream. These filtration stages are followed and supported by an outer stainless steel core, which also protects the element against pressure shock.

AG Compressed Air Filter Housings
Donaldson AG Compressed Air 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. Featuring a three-part aluminum design allows for easy disassembly and element change-out. Low pressure drop is achieved through optimal flow-path design. The tapered bowl and non-turbulent lower filter zone assure that no condensate gets re-entrained in the air stream. AG filter housings are equipped with our programmable Economizer differential pressure gauge, which notifies maintenance personnel of the optimal point at which to change the filter element. For coalescing pre-filters, AG filter housings with optional Ultramat zero air loss drain valve which assures that no compressed air is lost when liquid condensate is drained. All AG housings and elements are available in silicon-free configurations.
