Blackmer single and two stage reciprocating gas compressors create a low-pressure area in the pumping chamber when the piston moves from the highest point of the stroke to the lowest point. Gaseous product (at a higher pressure in the tank) moves into the pumping chamber of the gas compressor. This volume of gas is then displaced when the piston moves to the top of the stroke. Equipped with high efficiency valves, ductile iron pistons, self-adjusting piston rod seals and other robust features, these reciprocating gas compressors are designed to provide maximum performance and reliability under the most severe service conditions. They are also a critical component in the design of oil and gas vapor recovery units (VRUs).

These gas compressors are available in three model series - LB, HD and NG. The LB Series is ideal for the transfer and recovery of gases including propane, butane, LPG and anhydrous ammonia. The HD Series reciprocating gas compressors are suited for the movement, transfer and recovery of liquefied gases such as carbon dioxide and refrigerants, nitrogen, air, and numerous other industrial, petrochemical, and hazardous gases. The NG series is built for usage with natural gases.
