Donaldson Compressed Air & Process provides particulate, coalescing and carbon elements for compressed air and natural gas applications. We engineer and manufacture elements that provide lower pressure drop, longer filter life, quick and easy element change-outs and more predictable maintenance.
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.
M/S Coalescing Filter Elements
Donaldson M and S coalescing filter elements
are designed for removal of water, oil aerosols, and solid particles from compressed air and gas industrial applications. M/S elements utilize a three-dimensional polyester microfiber fleece media, which is ideal for coalescing and draining away oil and water aerosols in the air stream.
V Coalescing Filter Elements
Donaldson V coalescing filter elements
are designed for removal of water, oil aerosols, and solid particles from compressed air and gas industrial applications. The V elements utilize a three-dimensional polyester microfiber fleece media, which is ideal for coalescing and draining away oil and water aerosols in the air stream.
P Particle Filter Elements
Donaldson P prefilter elements
are designed for removal of solid contaminants in gases. P elements utilize 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.
B Particle Filter Elements
Donaldson B prefilter elements
are designed for removal of particulate contaminants in gases. B elements utilize a highly porous sintered media for absolute filtration of particles down to 25 μm in size. Although B is primarily used as a particulate prefilter, a simple reversal of flow through the element allows B filter elements to be used for effective course coalescing, removing bulk quantities of water and oil from an air or gas stream.
A Activated Carbon Vapor Filter Elements
Donaldson A adsorption filter elements
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, supported 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.
FF, MF & SMF Coalescing Filter Elements
The FF, MF, and SMF coalescing depth filters
are used for the removal of water, oil aerosols and solid particles from compressed air and gases with absolute retention efficiency.
Synteq™ XP M/S Coalescing Filter Elements
The new high performance filter media Synteq XP combines two innovations in one product: an engineered blend of fibers with proprietary, resin-free bonding system. Donaldson Synteq XP filter elements
combine the highest filtration performance with high stability, exceptional dirt-holding capacity and very good flow rates at low differential pressure.
PE Particulate Elements
Donaldson PE particulate filter elements
are made with aluminum end-caps, double o-ring seals and sintered polyethylene media for effective filtration down to 5 μm. PE elements offer the additional advantage of being fully regenerable.
SB High Temperature Filter Elements
For high temperature applications up to 248 F,Donaldson SB filter elements
are made with sintered bronze media, aluminum end-caps and double o-ring seals. SB elements are available with three retention ratings: 5, 25 or 50 μm.
AK Activated Carbon Filter Elements
The Donaldson AK Adsorption filter elements
utilize a two-stage filtration process for removal of oil vapor and other hydrocarbons. This proprietary two-stage design allows for a large surface area resulting in low pressure drop, long element life and no carry-over of carbon particles in the process air.
