Haun Specialty Gases, Inc is an authorized Purity Plus Specialty Gas distributor and the only gas company in Central New York with on-site filling and analysis capabilities.

Opened in 2005, the specialty gas production facility was designed with you in mind. We are able to complete your order quickly and efficiently because it’s filled and certified locally. 

Specialty gases are special purpose gases used for testing, instrument calibration, or as process gases. They are purer and have tighter tolerances than industrial gases. Haun offers Ultra High Purity Gases,


Calibration Standards, Laser Gas Mixtures, Multi-Component Blends, NIST Traceable Mixtures, Zero Gases, and EPA Protocol Mixtures.

Gas types filled at our facility are Air, Argon, Carbon Dioxide, Helium, Nitrogen, Oxygen, Propane, Propylene, and mixtures of these and many more components.

A full line of gas controls and delivery equipment includes regulators, filters, flow meters, traps, purge assemblies, and purifiers as well as manifolds, gas generators, pressure gauges, purgers, and valves. Haun supplies leak detectors, CO2 equipment, hoses, pumps, connection fittings, high voltage indicators, heaters, and a complete line of cylinder accessories. Hardware, fabricated from materials compatible with the gases you are using, provides reliable, contamination-free delivery of gas products from the source to the application.
Pure gases are filled using temperature /pressure charts. Individual mixed gas cylinders requiring tight blend tolerances are filled gravimetrically. After filling, each cylinder is rolled to prevent separation of molecules.

Mixes are analyzed and calibrated against known standards. Certificates of analysis are supplied either per cylinder or batch of cylinders.

Our Knowledgeable full time Specialty/Medical gas sales people are available to provide the guidance and support you need to resolve regulatory, technical, and safety issues. One call does it all!
