Blackmer HD Compressor

Blackmer HD Compressor

Blackmer was incorporated in 1903 and is the leading manufacturer of positive displacement pumps, centrifugal pumps and compressors for the transfer of liquid and gas products. Blackmer HD process compressors provide efficient and quiet delivery of oil-free gas or air. These heavy-duty single and two-stage compressors combine advanced design technology and state-of-the-art materials to give maximum performance with minimum maintenance. These compressors are well suited for handling a wide range of industrial gases, including propane, butane, propylene, vinyl chloride and chemical intermediates as well as many others, such as ammonia, carbon dioxide, refrigerants, air and nitrogen.
