\u2014 is a high-quality device intended for use in heat pumps<\/a>. It works in reversible cycle<\/a>. It is designed to allow flow in the pump liquid line in both directions. Reversible filter drier SFK-306<\/strong> It is used for refrigerants R12, R22, R32, R502, R134a, R404A, R407C, R410A, R507, R32. Also for CFC, HCFC, HFC and specific lubricants. Filtration capacity reaches 0.10 microns. The internal control valve, made of nylon, ensures filtration in both directions. The removal of organic and inorganic acids is done with the help of activated aluminum oxide, and the moisture is removed with a molecular dryer. The addition of activated carbon in the drying core helps to remove wax at low operating temperatures.<\/p>\n<\/div>\n<\/div>\n

The model SFK-306 SAE<\/strong> (or ZRK-306, BFK-306) has a solid core consisting of a mixture of molecular sieve and activated aluminum. These adsorbents are fixed in the core using a synthetic adhesive material. The core is tightly tightened on both sides, and cotton pads are placed for protection. The retaining veins inside the filter direct the flow, which allows the fluid to operate in any direction in heat pumps. This construction ensures high filtration efficiency and absorption of water and acids. Reversible filter drier SFK-306<\/strong> is available with SAE 3\/4\u2033 threaded connection. We also offer models with 3\/4\u2033 ODF solder connection. For further details, please contact us.<\/p>\n
