Compressed Air Filter DD15+

£216.90 inc Vat | £180.75 ex VAT

Compressor element lubrication and your compressor installation itself can release oil aerosols and wet dust in your air system. DD+ filters efficiently remove these contaminants to protect your equipment and your processes. These innovative filtration solutions are engineered to cost-effectively provide the best air purity and meet today’s increasingly stringent quality requirements.  The DD (+) is a high-performance oil coalescing filter that removes contaminants such as liquid water, oil aerosol up to 0.1ppm and particle size down to 1 micron.
