Service Life

RFLD duplex filter itself life is not fixed, its use and the cleaning and quality of the filter element is related, if the use of working conditions impurities too much, the filter may inhale more unclean gas, then increase the filter working pressure. Too many impurities will also quickly block the filter element, but do not insist on using it when you find that the filter element is blocked and broken, fine particles and impurities will enter the lubricating oil of the system and accelerate the oxidation of the lubricating oil.
