Sintered Polyethylene filter elements offer a good 1^st line of defense in a compressed air system. Low pressure drop and a large micron rating (25 micron) combine to remove general contaminant whilst providing a long service life. These filter elements can also be regenerated therefore extending the life of the element further. The standard range of particulate filters go from 12 to 30,000 cfm. PFS can design the housing right for you application if it does not fall into this range.
