DF Standard / Plus / Superplus
The filters Ultra-Filter DF are intended for the processing of compressed air or other gases in different areas of applications. A bayonet fixing between filter head and filter bowl allows for the element to be removed together with filter bowl. Little installation height for the filter element exchange is required. Besides energy cost savings by the filter design, the use of the Economizer offers further saving achievements through timely replacement of the used filter elements. The most cost effective replacement time for the filter element is calculated and LEDs signal the necessity for a "filter exchange". With 9 sizes the Ultra-Filter covers the performance range from 35 to 1100 m³/h flow rate and hence conventional compressor capacities between 2 and 120 KW. Three versions are available:
Standard
(with Econometer and float drain)
Plus
(with Economizer and float drain)
Superplus
(Economizer with level-controlled condensate drain UFM-T)

Ultrair M, S Coalescence filter
The depth filter for the removal of water, oil aerosols and solid particles from compressed air and gases in industrial applications. The filter elements type M and S are based on the three-dimensional micro fibre fleece made of coated borosilicate glass fibers, which works oil and waterrejecting.
Retention rate related to particles 0.01 μm:
S = 99,99998%
M = 99,9999%

Ultrair V Coalescence filter
The depth filter for the removal of water, oil aerosols and solid particles from compressed air and gases in industrial applications. The filter elements type V possess the three-dimensional micro fibre fleece made of polyester, which works oil and waterrejecting.

Ultraporex B Particle filter
The prefilter for the removal of oil, water and dust particles with absolute retention efficiency. The Ultraporex prefilter contains the highly porous sinter bronze filter medium. It ensures the retention of coarse solid and liquid particles. Retention rate, 100% in gases; defined retention rate of particles larger than the pore size (25 μm).

Ultrapoly P Particle filter
The prefilter for the removal of solid contaminants in gases. The Ultrapoly prefilter contains the high porous, sintered polyethylene filter medium. Even finest dust particles and other contaminants in compressed air and gases are being removed effectively on the surface and in the depth of the filter medium. Contaminants down to the size of 25 μm particles, are being retained in the filter.

Ultrac A Activated carbon filter
Adsorption filter for the removal of oil vapour, hydrocarbons and odours. The adsorption filter Ultrac A consists of 2 filter stages. At the adsorption stage oil vapour, hydrocarbons and odours are removed by activated carbon adsorption. Particles are removed at the depth filter stage, consisting of microfibre fleece. In addition, support fleece and an outer stainless steel support sleeve ensure proper fixation of the adsorption and filter stage. The flow direction through the filter is from inside to outside. At appropriate pre purification a residual oil content of < 0,003 mg/m³ is achieved.

DF-C Cyclone Separators
A cyclone separator has to remove the abrasive contamination, like solid and liquid particles and aerosols from the flow of air pressure. The emphasis is set here on the removal of water, which due to a condensation in the aftercooler at this point increasingly show as droplets or splashing water. Because of its low differential pressure and simultaneously lowered requirement of energy the cyclone separator offers substantial cost savings. In addition the higher filtration efficiency takes a positive effect on the subsequent compressed air adsorption and refrigeration dryers as well as on the filters. The DF-C cyclone separators are available in six sizes, which match the current compressor capacities and the connection sizes of the Donaldson compressed air filters as well as the refrigeration and adsorption dryer product range. In addition, they are integrated in the current compressed air filter housing generation as the “Standard” (equipped with time-controlled condensate drains) or “Superplus”-Version (equipped with Ultramat UFM-T level-controlled condensate drain).

SG Standard / Superplus
SG Standard and SG Superplus carbon steel filter housings are designed to DIN 2633 standards with flange connections. In the Standard configuration, these housings include our Econometer differential pressure gauge and external float drain valve for coalescing applications. Superplus versions include our programmable Economizer differential pressure gauge which notifies maintenance personnel of the optimal point at which to change the filter element(s). Superplus models also include our Ultramat zero-loss condensate drain which assures that no compressed air is lost when liquid condensate is drained. All SG housings and elements are available in silicon-free versions.

Ultradri SG-Z Cyclone Separators
Ultradri SG-Z (carbon steel) separators are designed to remove liquid condensate from compressed air and gas. Integral swirl vanes allow for efficient liquid removal with low pressure drop. SG-Z housings incorporate an additional baffle plate to prevent carryover of condensate. Standard configurations are equipped with UFZ condensate drains while Superplus versions are equipped with Ultramat zero-loss drain valves.
