QD(+) SERIES

High performance oil vapor filters

QD(+) filters efficiently reduce hydrocarbons, odors and oil vapor in your compressed air stream to protect your investment, equipment and processes. The activated carbon layers will, by the use of adsorption, reduce the residual oil content to less than 0.003 mg/m³. The pressure drop is low and stays minimal during the lifetime of the filter.

Your Benefits

• Maximum oil vapor removal
  Highly efficient activated carbon layers.
• Significant energy savings & limited system operating costs
  Low pressure losses.
• High reliability
  High-performance stainless steel cores, double O-rings, epoxy sealed caps, and anti-corrosive coated filter housing.
• Easy maintenance
  External ribs on the threaded housing, or a rotating bottom cover for the welded housings, and push-on elements.

Certified Performance

Atlas Copco filters are qualified according to the ISO 8573-1:2010 standard. This is the latest edition of the standard. Beware of filters that comply with earlier editions, such as ISO 8573-1:1991 or ISO 8573-1:2001. The difference is inferior quality of the delivered compressed air. This qualification is a result of our filters being tested according to ISO 12500-1:2007, ISO 12500-2:2007, and ISO 12500-3:2009. These specify the test layout, test procedures and inlet conditions required for testing coalescing filters, vapor filters, and solid particle filters used in compressed air systems, to determine their effectiveness in removing oil aerosol, oil vapor and solid particles. The measurements of the air purity downstream the filter for each specific contaminant have been performed according to the test methods described in respectively ISO 8573-2:2007, ISO 8573-5:2001 and ISO 8573-4:2001. Tests have been conducted in-house as well as in external labs, and are independently validated by TÜV. ISO

A Solution For Every Application

At different points of use, different compressed air purities might be needed, depending on the application. The various air purity classes are provided in the table below, which clearly shows the various Atlas Copco filters and dryers that meet all the different classes.
