Compressed Air Filters

Without proper treatment, compressed air contains solid, liquid and gaseous contaminants which reduce the efficiency of your compressed air system, increase your operating expenses, and jeopardize product quality.

DD+, DDp+, PD+, PDp+, QD+ filters (standard and high pressure): Compressed air filters

Contaminating particles and oil carryover can have a serious effect on the wear and operation of pneumatically operated equipment. Specially designed Atlas Copco DDp, DD, PD, and QD filters effectively eliminate contaminants, assuring clean air. Particulate removal as low as .01 microns and oil removal at maximum remaining content of .003 ppm are achieved.

Atlas Copco’s DD+, DDp+, PD+, PDp+ and QD+ filters efficiently reduce all types of contamination in your compressed air stream to protect your investment, equipment and processes. Our innovative filtration solutions are engineered to cost effectively provide the best quality air and meet today’s increasing quality demands.

Customer benefits

• Reduced energy costs – Designed for maximum contaminant removal, our filter range offers significant energy savings thanks to their optimal air flow path with low resistance. The filters’ carefully engineered housing and cartridge ensure minimal pressure drops.

• Solid reliability – High performance stainless steel filter cores ensure durability of the cartridges. Protection paper avoids direct contact between the filter media and the stainless steel filter core.

• High efficiency – Top quality filter media in a deep-wrap layered composition ensure extremely high filtration efficiency, a low pressure drop and long cartridge lifetime. The flow path through housing and cartridge is optimized to reduce air turbulence and pressure drop.

• Low running costs – A unique and highly efficient head design reduces pressure drop and cuts your operational costs.

Technical Specifications
Capacity FAD	19 - 19080 cfm
Max design pressure: 16 bar for standard range, 20 bar for high pressure range. DDp+, PDp+ are dust filters. DD+, PD+ are oil coalescence filters. QD is an oil vapor filter.

 

QDT: Activated carbon tower, 20-310 l/s, 42-657 cfm.

In the pharmaceutical, food & beverage, electronic and other industries where air purity is critical, you often need to remove residual oil vapors and odors from the compressed air supply. That is exactly what Atlas Copco’s high-efficiency carbon filter does. The QDT activated carbon towers will, through the process of adsorption, reduce the residual oil content to lower than 0.003 mg/m³ at 35°C/95°F and 7 bar inlet pressure. The pressure drop is low and stays minimal during the lifetime of the filter. Only an activated carbon tower is able to provide Class 1 clean air in accordance with ISO 8573-1.
