Down stream air Filters DDx, PDx, DDxp, PDxp, QDx


You need pure compressed air

If Compressed air is the energy source behind your production, you depend on its economic and efficient operation.

Every cubic meter of air contains 140 million particles of dirt. These particles, mixed with water vapour and hydrocarbon vapours from unburnt fuels and industrial processes, are drawn into the compressor and concentrated under compression.

After compression. all these contaminants can combine in the piping system with condensed moisture, pipe scale and rust, creating a damaging abrasive emulsion.

Atlas Copco has developed a perfectly matched filter system, which reduces all types of contamination right from the source according to your individual requirements.


Atlas Copco range to meet your compressed air quality needs.

Atlas copco offers you 4 ranges of filters:

DDx range: Coalescing filters for general purpose protection, removing liquid water and oil aerosol to 0.1 mg/m (0.1ppm) and particles down to 1 micron. -DDxp range: Particulate filters for dust protection, removing particles down to 1 micron.



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



PDx range: High efficiency coalescing filters, removing liquid water & oil aerosol to 0.01 mg/m (0.1 ppm) and particles down to 0.01 micron.



PDxp ramge: High effective particles filters particles down to 0.01micron.



QDx 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) should installed after a PD filter.



Energy costs of high pressure drop

Atlas Copco's filters are designed to combine maximum contaminated removal efficiency with minimum pressure drop, resulting in a low energy consumption in your compressed air system keep in mind that 150 mbar extra pressure drop will cost you, 10,000 KWh extra energy per year in a 500 I/s compressed air system operating at 7 bar,6,000 hours per year.

 

 

How they work?



DDx,PDx,DDxp and Pdxp filters are coalescing and particulate filters, The key to effective filtration is to optimize the filtration mechanisms through the filter media of borosilicate microfibres:

Direct interception: The large particles are intercepted because the distance between two fibres is smaller than their size.

Inertial impaction: The heavy particles connot follow the curved path developed because of the large numbers of fibres. They collide against a fibre and remain suspended in it.

Diffusion (Brownian movement): The smallest particles are in random motion due to the thermal agitation of the air molecules. Eventually. these particles run into fibres to whcih they adhere.

QDxFilters are active carbon filters. The filtration medium is impregnated with active carbon to remove hydrocarbon vapours by adsorption.

Adsorption: Active carbon presents large specified area and affinity for oil vapours.Oil molecules accumulate in the active carbon surface.
