(5) Particulate filters remove harmful oil/water condensate, pipe scale, dirt and rust from you compressed air system. This prevents corrosive damage to compressed air equipment and finished products. Typically, particulate filters are installed upstream of regulators to prevent valve failure. They are also used as pre-filters to oil removing and coalescing filters to insure high efficiency and long element life in applications such as paint spraying, instrumentation and pharmaceuticals.
(5) Arrow's Oil Removing Filters offer general industrial filtration with low pressure drop and long element life. They are used with older compressors where downstream oil carryover is excessive and when longer element life and low pressure drop are a concern.
(5) A coalescing filter functions in a different way from a standard particulate filter. Air flows from inside to outside through a coalescing media. Coalescing, by definition, means "To come together". It is a continuous process by which small aerosols come in contact with the fibers in the filter media, uniting with the collected aerosols and growing to emerge as a droplet on the downstream surface of the media which by its weight is gravitationally drained away. For maximum performance and efficiency, coalescing filters should be preceded by and F3 particulate filter.
