Atlas Copco offers compressed air filters with improved filtration efficiency and decreased pressure drop to improve air quality and conserve energy. Atlas Copco’s DD+ and PD+ for the filtration of oil aerosols and DDp+ and PDp+ filters for solid particles are certified to ISO standards. Micro-glass fiber filter media and a six-layer wrapped construction ensure purity filtration and performance over the lifetime independent of relative humidity. Perforated stainless steel metal cores were improved to ensure mechanical strength and to reduce the risk of implosion. Compared to previous generations, the DD+ and PD+ filters offer reduced pressure drop and a 20% decrease in oil carry over, while DDp+ and PDp+ filters offer particle removal efficiencies of over 99%.
