Filter drier 307 SAE 7/8″

The 307 SAE 7/8″ filter drier features a solid core made from a mixture of molecular sieve and activated aluminum. The adsorbents are secured using a synthetic adhesive material for high absorption and filtration efficiency. The robust construction and internal protective elements ensure reliable operation and a long service life.

307 SAE filter drier available with SAE 7/8″ threaded connection, as well as in versions with 7/8″ ODF solder connection. For additional information and compatibility with your system, contact us.

FAQ – Filter drier 307 SAE (7/8″)

1. In what types of systems is the 307 SAE filter used?

The 307 SAE filter drier is used in medium and large capacity refrigeration installations, including industrial chillers, refrigeration units and air-to-water heat pumps. Thanks to the 7/8″ SAE connection, it is suitable for liquid lines with high flow and stable pressure.

👉 Compatible applications:

/chiller-industrial-r32
/commercial-refrigeration-systems

2. Is 307 SAE compatible with modern inverter compressors?

Yes, the 307 SAE filter is commonly used with inverter scroll or rotary compressors, especially in systems operating with R410A and R32. Its role is to protect the compressor from moisture and fine particles that can cause premature wear.
