Air Filters
Unfiltered compressed air frequently contains dust, oil, rust, moisture, and other harmful substances, and therefore requires filtration The presence of contaminants may have highly damaging effects such as corrosion, wear and tear on the finely finished mating surfaces of pneumatic components. Air lines may get chocked or damaged. Therefore, purification of air by removing oil, moisture, and dust is done to protect the pneumatic system from failure, so that the system should work efficiently
Cleaning up an air or gas supply can be as easy as installing a filtration system. These systems employ one or more filters to remove contaminants before they reach the pneumatic equipment
Types of air filters
Particulate filters
Particulate compressed air filters are used to remove dust and particles from the air.
Activated carbon filters
Activated carbon filters utilize a composite carbon material to remove gases and odors from the air. They are used in factories where food is produced or for breathing gas.
Oil filters
High oil compressed air coalescing filters remove water and oil aerosols by coalescing the aerosols into droplets. This happens partially because of the tortuous path and pressure drop. Coalescers remove both water and oil aerosols from the air stream and are rated at particulate contamination through direct interception. Filtration of oil, water aerosols, dust, and dirt particles to 0.01 µm the best achievable in the industry.
