Gas Compressors & Blowers

A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.    

Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible, so the main action of a pump is to pressurize and transport liquids.

Sunair Co. is able to assist you with a wide variety of industrial and municipal process gas compressors, ranging from hydrogen recycle to landfill gas extraction, vapor scavenging, and everything in between.

We are a Stocking Distributor and Factory Authorized Service Center Representing two market leading manufactures of process gas compressors:  Sundyne Corporation and Blackmer Compressors. 

Sundyne Integrally-Geared Centrifugal Compressors

Sundyne Centrifugal Compressors have been applied in a multitude of process gas applications over the past 4 decades. Our low-flow, high-speed, integrally geared technology provides pulsation and oil free flow in a compact yet rugged design. With API-617/614 ratings, Sundyne Compressors are engineered to last and require minimal maintenance.

Typical applications include corrosive gases, polypropylene, regeneration, recycle, vapor recovery, fuel gas, LNG, ethylene, acetic acid, acetylene, hydrogen, atomizing air, chlorine, gas boost, and high suction pressures.

Blackmer Reciprocating Compressors
Blackmer single and two-stage, reciprocating 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. 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 compressors are designed to provide maximum performance and reliability under the most severe service conditions.

Typical applications include pressure boosting, liquefied gas transfer, vapor recovery, tank scavenging, railcar unloading, ammonia, LPG, refrigerants, butane, propane, propylene mixtures, pressure padding, carbon dioxide, and oil-free process nitrogen or air.
