Filtru deshidratator reversibil SFK-306 SAE 3/4″

Technical features

The model SFK-306 SAE (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 is available with SAE 3/4″ threaded connection. We also offer models with 3/4″ ODF solder connection. For further details, please contact us.
