Factory-welded with a 3\/8\" (10 mm) copper connection, each drier handles working pressures up to 4690 kPa and is suitable for horizontal or vertical installation. The combination of epoxy-coated exterior and molecular sieve interior helps extend compressor life and preserve system efficiency by keeping refrigerant dry and contaminant-free.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this filter drier protect my heat pump or refrigeration system?\u003c\/h3\u003e\n\u003cp\u003eThe EK-083S is a unidirectional flow drier that traps moisture, acids and fine particulates before they circulate through compressors, expansion devices and heat exchangers. By maintaining dry, clean refrigerant, it reduces the risk of valve corrosion, clogging and ice formation on thermostatic devices.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMolecular sieve core absorbs water and acidic byproducts.\u003c\/li\u003e\n  \u003cli\u003eFine filtration removes metal shavings and debris.\u003c\/li\u003e\n  \u003cli\u003eEpoxy-coated shell resists external corrosion in mechanical rooms.\u003c\/li\u003e\n  \u003cli\u003eRated to 4690 kPa for common residential\/commercial systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it fit my 1–5 ton HFC heat pump or straight cool air conditioner?\u003c\/h3\u003e\n\u003cp\u003eYes.
