Compressors Series HDL 320

BLACKMER HD Series - Compressors for many industrial applications with a large number of industrial gases


BLACKMER Industrial Compressors Series HDL320


The liquid-cooled Blackmer HDL320 Series single-stage, two-cylinder reciprocating gas compressors feature flow rates of 9 CFM (23.1 m³/hr) at max rpm. For precise leakage control and to minimize product contamination, the HDL320 Series gas compressors features a double-seal (HDL322) model. All HD Series Compressors are equipped with thick and robust wear parts – piston rings, needle bearings, and high-efficiency valves that will keep the HD Series compressors operating long 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.
