The particle concentration and humidity increase after compressing the air. This creates an abrasive emulsion, which can cause considerable damages.

Tools can fail, spray paint or air can be rendered unusable, maintenance costs increase and products are spoiled.

The range of Atlas Copco DD, PD, DDp and QD filters can supply air in the right combinations under normal conditions between 9 and 7200 l/s.

DD Series

General purpose coalescing and particulate filters for the separation of liquid water and oil aerosols down to 0.1 mg/m³ (0.1 ppm) and particles down to 1 micron.

DDp Series

Particle filter for the removal of dust particles down to 1 micron.

PD Series

High performance coalescing and particulate filters for the separation of liquid water and oil aerosols down to 0.01 mg/m³ (0.01 ppm) and particles down to 0.01 micron.

QD Series

Activated carbon filters to remove oil vapors and hydrocarbon odors up to a maximum residual oil content of 0.003 mg/m³ (0.003 ppm). This filter should be installed after a PD filter.

Range of filters:

  • Max. flow rate: 9 to 7,200 l/s
  • Max. excess operating pressure: 16 bar
