New ‘Two-in-One’ Filters Reduce Pressure Drops by 40 Percent

/

At Atlas Copco, innovation is in our DNA. It’s also in the DNA of our new UD+ coalescing compressed air filters, which combine two filtration processes into one product and reduce pressure drops by 40 percent. UD+ filters are available with capacities of 19 scfm to 16,950 scfm.

How does the UD+ filter work?

The two-in-one UD+ filter utilizes wrapped filter technology, where an innovative glass fiber filter media package is wrapped around the filter core. Traditionally, two in-line filters are 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. However, extensive testing has shown that the UD+ can achieve the same excellent air quality of two traditional filters due to its innovative filtration technology.

The design of the UD+ is unique in the market and offers energy savings, efficiency gains and reliably clean compressed air. But don’t just take our word for it. The UD+ is certified according to ISO 12500-1:2007 and ISO 8573-2:2007 standards by TÜV Rheinland.
