Atlas Copco pioneers two-in-one coalescing filter technology

The UD+ is the newest addition to Atlas Copco’s extensive line of compressed air filter solutions. This two-in-one filter combines the reliability and performance of wrapped filters with a 40% reduction in pressure drops compared with pleated filters.

“Our compressed air solutions are of the highest quality, so our air treatment solutions should be too,” explains Paul Clark, Business Line Manager, Industrial Air. “With the UD+, we have launched a compressed air filter innovation that saves space, energy and money without compromising on reliability and air quality.”

Traditionally, two inline filters are needed to bring oil aerosol and solid particles in the compressed air down to acceptable levels for most applications (ISO 8573-1 Oil class 1 and 2; ISO 8573-1 Solid particle class 1). The UD+ replaces those two filters, saving space and reducing pressure drops by 40%. Extensive testing has shown that the UD+ achieves the excellent air quality of two traditional filters, thanks to the glass fibre filter media package that is wrapped around the filter. This technology is not only more efficient, it also offers increased reliability over traditional, pleated filters, which are prone to cracking.

The UD+’s reliability and performances are certified according to ISO 12500-1:2007 and ISO 8573-2:2007 standards by TÜV Rheinland. Available models range from a capacity of 9 l/s to 8000 l/s.
