High Pressure

HDDP / HQD : High-pressure air filters for 40 bar (580 psig) applications

Atlas Copco’s HDDP and HQD air filters are designed to be installed downstream of an oil-free air compressor equipped with a dryer, where they provide a high degree of air filtration. The HDDP is a high-efficiency fine filter for dust filtration. The HQD is an activated carbon filter which is installed after the HDDP fine filter for filtration of oil and vapor. Both are perfectly adapted to high-pressure processes in food processing applications.


Customer benefits

  • High efficiency – The HDDP is a highly efficient dust filter; its filter element traps solid particles down to 0.1 micron for 99.99999%. The HQD active carbon filter removes odors and oil vapor down to 0.005 mg/m3 oil carry-over.

  • High quality – Teflon coated, inside and outside.

  • Easy installation – HDDP and HQD filters can be installed on a multi-functional filter support allowing for floor or wall mounting of 1 or 2 filters.
