Atlas Copco has introduced UD+ coalescing compressed air filters available with capacities of 19 scfm to 16950 scfm, which combine two filtration processes into one product while reducing pressure drops by 40 percent.

“Our customers look to Atlas Copco to provide the highest quality compressed air solutions throughout the entire compressed air system, including the air treatment equipment,” said Robert Eshelman, vice president, Industrial Air Division, Atlas Copco Compressors. “The UD+ represents a major filter innovation that results in energy and cost savings without compromising reliability or air quality.”

The two-in-one UD+ filter utilizes wrapped filter technology—an innovative glass fiber filter media package wrapped around the filter core. Compared with traditional pleated filters, one UD+ filter is more efficient and reliable than two in-line filters that were previously required to bring oil aerosol and solid particles in the compressed air down to levels that meet ISO 8573-1 Oil Class 1 and 2 and ISO 8573-1 Solid Particle Class 1 standards.

“The UD+ is unique in the market and offers energy savings, efficiency gains and reliably clean compressed air,” said Eshelman. “Extensive testing has shown that the UD+ can achieve the same excellent air quality of two traditional filters. The unique design also results in a more reliable filter than traditional pleated filters which are prone to cracking.”

The UD+ comes equipped with the highest quality protection layers and a thick package of wrapped, enhanced glass fiber filter media. The UD+ is certified according to ISO 12500-1:2007 and ISO 8573-2:2007 standards by TÜV Rheinland.
