Atlas Copco Receives Class 1 Certification for UD+ QDT Filter Combination

Atlas Copco Airpower confirms its leadership in filtration through certifications and significant energy savings.

ROCK HILL, S.C. - Atlas Copco Airpower is one of the first players in the compressed air filtration industry to receive ISO 8573-1:2010 class 1 certification for its UD+ QDT filter train.

Atlas Copco's two-in-one coalescing UD+ filter combined with the newly redesigned activated carbon tower QDT allows for an oil content far below 0.01 mg/m3, the maximum allowed total oil content for class 1, said Isabelle De Wolf, head of the filtration RD team of Atlas Copco Airpower.

This was proven through independent tests conducted by the TÜV Institute, a global provider of technical, safety, and certification services.

"Atlas Copco's UD+ filter takes wrapped filter technology to a new level, combining the reliability and performance of wrapped filters with pressure drops lower than even pleated filters can achieve," De Wolf said. "The result is an astonishing 40 percent energy efficiency improvement compared to traditional filters."

The redesigned QDT activated carbon tower removes the residual oil vapors and odors from the compressed air supply. With optimization of the activated carbon material and internal flow path, the tower improves energy efficiency by an average 65 percent while continuing to provide air purity, a small footprint, and a long lifetime.

"With these achievements and the class 1 certification, Atlas Copco strengthens its commitment to deliver pure, clean air to the industry at the lowest possible energy cost," said Horst Wasel, President for the Medical Gas Solutions Division.
