FILTERS FOR COMPRESSED AIR
The high efficiency filters threaded DD+ types, DDp+, PD+, PDp+, QD+ and UD+ have been specially developed by Atlas Copco to remove solid particles, liquid water and oil in varying degrees according to ISO 8573-1.
With these filters, substantially improves the quality of compressed air and give significant benefits of cost reductions.
Filter cartridge for compressed air filters
► DD+ FILTERS: Coalescing for general protection, remove liquid water and oil aerosol to 0.1 mg/m3 (0.1 ppm) and particles down to 1 micron. The degree of filtration is 2-2 according to ISO 8573-1.
► PD+ FILTERS: High efficiency coalescing filters, remove liquid water and oil aerosol to 0.01 mg/m3 (0.01 ppm) and particles down to 0.01 micron. The degree of filtration is 1-1 according to ISO 8573-1.
► QD+ FILTERS: Activated carbon filters to remove oil vapors and hydrocarbon odors with a maximum remaining oil content of 0.003 mg/m3 (0.003 ppm). The degree of filtration is 1-1 according to ISO 8573-1. These filters should be preceded by a PD.
► UD+ FILTERS: UD+ filters efficiently reduce all types of contamination in your compressed air stream to protect your investment, equipment and processes. Thanks to its unique glass fiber filter media package, the UD+ offers a two-in-one filter technology, combining two filtration processes in one product. The UD+ offers the same reliability and high air purity as traditional filter packages (with two filters), but reduces pressure drops with 40% and saves space.
These filters have a surface treatment that protects against corrosion.
DD+ and PD+ types include an automatic air vent, while the QD+ a manual purge.
In sizes 50 (l / s) and higher includes a differential pressure gauge to check the status of the filter cartridge, while the lower models have a pressure gauge.
All filters have security buzzer.
The filter cartridges are double o-ring seal to ensure that no internal leakage of unfiltered air.
