Designed with both air-cooled and liquid-cooled models, the Blackmer HD370 Series two-stage reciprocating gas compressors feature flow rates of 24.1 CFM (40.8 m³/hr) at max rpm. The HD370 Series gas compressors have four models available, the air-cooled (HD372/373), and liquid-cooled (HDL372/373) models. For precise leakage control and to minimize product contamination, the HD370 Series gas compressors offer double- (HD372/HDL372), or triple-seal (HD373/HDL373) 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.
