Compressed Air Filter DD25+

£272.84 inc Vat | £227.37 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.

Filtration Solutions For Quality Air

Maximum Filtration & Highly Efficient Drainage

Maximum Filtration & Drainage

Oil aerosol, wet dust and water droplet filtration and drainage. High-efficient glass fibre and foam media.

Energy & Cost Savings

Optimal design and filter media allow low-pressure losses.

High Reliability

High-performance stainless-steel cores, double O-rings, epoxy sealed caps, and anti-corrosive coated filter housing.

Easy Maintenance

External ribs on the threaded housing, or a rotating bottom cover for the welded housings, and push-on elements.

Monitoring of Energy Use

Differential pressure indication (indicator for sizes 10-35 l/s, gauge for sizes 50-8000 l/s) (optional for standard range)
