Airvac SC Series – Single Stage, Single Cone, Liquid Ring Vacuum Pumps, and Compressors

Airvac AV SC series liquid ring vacuum pumps are versatile, single- stage pumps designed for demanding applications in harsh environments. They are commonly used in industries like paper, mineral processing, and food processing for tasks such as dewatering, filtering, and evaporation. Their robust design and ability to handle various gases and liquids make them suitable for a wide range of industrial processes.

We have directly interchangeable parts with the NASH* Classic SC.
The AV SC Series single stage liquid ring vacuum pumps and compressors are drop-in
replacements, completely interchangeable with the Nash* classic SC series models ranging
from 70 to 1700 CFM and 7.5 to 150 HP, up to 25 psig of maximum compression. AVSC
vacuum pumps are applicable to a variety of dirty jobs that require a robust pump, such as
poultry evisceration and exhausting. AVSC pumps and compressors are factory
performance tested and include a 2-year warranty.
