Atlas Copco Filtration

A complete filter range to protect your equipment and process from particles and oil.

DD/DDp/PD/PDp/QD Series High Pressure Filtration

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 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 0.1 mg/m (0.01 ppm) and particles down to 0.01 micron.
