Rosco ProCom supplies filtration products and solutions for industrial application which includes air intake filters, compressed air/gas particulate and coalescing filters, oil mist elimination and liquid process filtration.

Inefficient intake filtration permits contaminants to corrode, erode and foul internals. Custom filtration systems can be used for virtually any air, gas and liquid applications. Selecting the right filter type and media depends on the specific operating conditions. Filter media components range from; natural and synthetic materials, such as polyester, glass fiber (woven or needle-felted), PTFE, cotton and stainless steel.

Engineering value added solutions to new filtration problems has been the Dollinger® tradition since 1921, when the first air intake filter for farm tractors was developed to protect engines from abrasive dust. Today, Dollinger is headquartered in Ocala, FL, U.S.A. and is part of SPX, the leading global manufacturer of filtration and dehydration equipment.

Dollinger provides customers with precision-engineered air intakes, fuel/oil filtration packages, oil exhaust eliminators, lubrication systems, hi-speed turbo compressors, turbines and blowers. All filtration products are environmentally friendly, while ensuring the capture of fugitive oil mist emissions which can present health and safety issues.

Air Intake Filters

Contaminants at the intake of compressors, blowers and turbines dramatically affect the cost of supplying compressed air. Dollinger air intake filters will deliver optimum performance, energy savings and protection to gain long component service life.

Air, Gas & Liquid Pipeline

High performance Dollinger in-line filtration products are designed to selectively target and remove unwanted contaminants like dirt, rust, pipe scale, oil and water from compressed air, gas or process liquids.

Oil Exhaust Filters

Dollinger oil exhaust filters are designed to recover fugitive oil mist emissions to lower operating costs, promote good health and improve safety. These highly efficient, dynamically engineered oil mist eliminator systems capture oil mist emissions from the lubricant reservoirs of high speed rotating equipment.
