PneumaticPlus, SAMD series separate and remove the oil particles or carbon and dust particles of size 0.01 micron or greater in the air sol state. Accordingly SAMD series are ideal for filtering the compressed air necessary for precision measuring instruments and clean room. 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 SAF particulate filter. Coalescing Filter are used for high filtration of oil aerosols and sub micron particles. They are often used with critical instrumentation; paint spraying equipment; more sophisticated air systems; blow molding bottling; in the food industry, and where air blows on a finished product. The 0.01 micron grade "a" element is offered for the most critical filtration applications, such as those found in clean rooms.
