Filter dehydrator KLE-307S ODF 7/8″

KLE-307S ODF filter drier features a solid core made of a mixture of molecular sieve and activated aluminum. The adsorbents are fixed 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.

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

1. Which compressors is the KLE-307S ODF filter drier compatible with?

Reversible filter drier SFK-306 SAE is used in refrigeration circuits where medium and large capacity compressors are installed, operating with R410A, R32 or R407C refrigerant.
It is commonly used together with scroll and inverter compressors in 12–40 kW air-to-water heat pumps.

👉 Compatible compressor models:
/scroll-r32-inverter-compressor
/compressors-for-industrial-heat-pumps

2. In which heat pumps is the KLE-307S ODF filter drier used?

This filter model is designed for installations with a 3/4" liquid line, being used in medium and high power heat pumps.
It is frequently installed in reversible circuits with heating/cooling operation.

👉 Examples of compatible equipment:
/industrial-heat-pump-600kw
/industrial-heat-pump-200kw

3. Can SFK-306 be combined with a freon sight glass?

Yes, the SFK-306 SAE filter is usually installed together with a freon sight glass on the same liquid line for monitoring refrigerant moisture and condition.
This combination helps to quickly diagnose the system and prevent compressor failures.

4. Are there alternative, more powerful filters for the same 7/8″ connection?

For applications with higher thermal load or high contamination, filter driers of the same 7/8″ connection class, but with extended absorption capacity or heavy-duty construction, can be used.
They are used in industrial installations or high-power heat pumps.
