New filters and carbon towers set high standard in risk prevention

20 May 2019

Atlas Copco introduced several new high-flow filters and activated carbon towers that offer the highest possible standards in preventing dust and oil contamination within oil-injected air compressors and air treatment systems.

Marine standards

The two new 16 Bar aluminium twin filter models, named UD 850T and UD 1100T, can be used in numerous applications and industries – even in challenging marine environments. 

Building on the existing aluminium filter line up to 2,000Nm³/h, they offer high flow filtration solutions of 3,000Nm³/h and 4,000Nm³/h respectively; at reference conditions of 7 Bar. 

The new filters are ISO12500-1 verified. This applies to all patented UD grade oil coalescing filters, which replace two traditional 1 micron and 0.1 micron coalescing filters with one single filter offering the same filtration rate at 40 percent less pressure drop.

Optimal risk prevention control

The existing QDT carbon tower range is expanded with five new 16 Bar fabricated vessels. The combination of the QDT activated carbon towers and the new twin filter UD+ type pre-filter and PDp type post filter offers optimal control to prevent the risk of oil and dust contamination.

When combined with GA oil-injected compressors, they guarantee ISO8573-2010 class 1 0.01mg/m³ oil content and class 1 particle content – which makes them a reliable alternative to the Atlas Copco Class 0 compressor portfolio.

With service intervals of either 8,000 or 12,000 hours and suitable for flows between 1,500 and 6,500Nm³/h, the QDT range now matches the entire compressor range up to 750kW.
