Reversible filter drier SFK-305 SAE 5/8″

Reversible filter drier SFK-305 SAE 5/8″

• 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 clamped 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 efficiency of filtration and absorption of water and acids.

Reversible filter drier SFK-305 SAE (ZRK305, BFK305, ZFK-305) is available with threaded connection SAE 5/8″. We also offer models with 5/8″ ODF solder connection. For further details, please contact us.

FAQ – Reversible filter drier SFK-305 SAE (5/8″)

1. Where is the SFK-305 SAE 5/8″ reversible filter drier used?

SFK-305 SAE filter drier is specially designed for reversible cycle heat pumps where the refrigerant flow changes depending on the heating/cooling mode. It is used in 5/8″ SAE liquid lines in small and medium-sized residential and commercial installations.

👉 Compatible applications:
/air-to-water-heat-pump-9kw-split
/air-to-water-heat-pump-12kw-r32
/awhp-series-inverter-heat-pumps

2. What compressors does the SFK-305 SAE work with?

This model is commonly used with scroll and rotary inverter compressors that work with modern refrigerants such as R32 and R410A. Its role is to protect the compressor from moisture and contaminants that can damage the valves and oil.

👉 Compatible compressors:
/compresor-scroll-Invotech
/scroll-compressor-Copeland
/compressors-heat-pumps-awhp-series

3. Can it be installed together with a freon sight glass?

Yes, the SFK-305 SAE is often installed together with a freon sight glass on the liquid line. This combination allows for visual checking of the refrigerant condition and quick detection of moisture or air bubbles in the circuit.
