About the FA-20L

The FA-20L Compressor is one of the smallest in SHI’s Freedom® series, and is a direct replacement for the discontinued HC-4A Zephyr® Compressor.  This low-volt, single-phase compressor is air-cooled and operates at 2.25-2.4/2.6 kW (50/60 Hz).  It pairs with several of SHI’s smaller Gifford-McMahon Cryocoolers and Marathon® CP Cryopumps.
