Low Pressure Liquid Ring Compressors 

Low pressure liquid ring compressors deliver reliable, proven performance for wastewater treatment, digester gas compression, aeration, and many other applications and industries. With a discharge pressure up to 30 psig (3 bar), Nash offers efficient, low pressure compressors with low maintenance requirements. Alternate seal liquids can be used when water is not compatible with the process gas. Our low pressure liquid ring compressors are available in stainless steel, ductile iron, and other optional materials.

Many NASH vacuum pumps can also work as low and medium pressure compressors.
