FILTERS - DD, DDp AND QD RANGES

After compressing the air, the concentration of particles and moisture increases. This creates an abrasive mixture that can cause extensive damage.

Instruments and tools can malfunction, spray painting and breathing air can be rendered unusable, maintenance costs will increase and products will be spoiled.

The range of Atlas Copco's DD - PD - DDp and QD filters, when used in the correct combinations, will provide high quality air from 9 to 7200 l/s at nominal working conditions

DD range:

Coalescing and particulate filters for general purpose protection, removing liquid water and oil aerosol to 0.1 mg/m (0.1 ppm) and particles down to 1 micron.

DDp range:

Particulate filters for dust protection, removing particles down to 1 micron.

PD range:

High efficiency coalescing and particulate filters, removing liquid water, oil aerosol to 0.01 mg/m (0.01 ppm) and particles down to 0.01 micron.

QD range:

Active carbon filter for removal of oil vapours and hydrocarbon odours with a maximum remaining oil content of 0.003 mg/m (0.003 ppm) to be installed after a PD filter.
