Blackmer Dual HD613B Industrial Reciprocating Gas Compressor Skid

HD610 Series Reciprocating Gas Compressors HD612, HDL612, HD613, HDL613

Available in air-cooled and liquid-cooled models, the Blackmer HD610 Series two-stage reciprocating gas compressors feature flow rates of 53.7 CFM (91.2 m³/hr) at max rpm. The HD610 Series gas compressors have four models available, the air-cooled (HD612/613), and liquid-cooled (HDL612/613) models. For precise leakage control and to minimize product contamination, the HD610 Series gas compressors offer double- (HD612/HDL612), or triple-seal (HD613/HDL613) models. Compared to competitive compressors, all HD Series Compressors are equipped with thicker and more robust wear parts – piston rings, needle bearings, and high-efficiency valves that will keep the HD Series compressors operating longer than the competition between maintenance cycles. Equipped with an array of features such as a ductile iron head and cylinders, steel pistons and self-adjusting piston rod seals, HD compressors provide maximum performance, energy efficiency, quiet operation, low maintenance cost and reliability under the most severe service conditions.
