The Tech Air Companies are proud to welcome Gasco Affiliates, LLC into the Tech Air family! The Tech Air Companies are distributors of medical, specialty, industrial and welding gases and related welding supplies and equipment. We have been providing the highest quality products, outstanding customer service and expert technical support to our customers throughout the United States for decades.

Gasco is the leading and only independent manufacturer of Precision Calibration Gas Mixtures. Gasco has the capability of providing a wide range of simple mixtures such as ultra high purity Nitrogen, as well as complex four gas mixtures and highly reactive gas mixtures. We offer the most extensive variety of standard cylinder sizes as well as the highest quality regulators, carrying cases and accessories available. Gasco has 80 years of combined gas detection, analytical instrumentation and sample handling. Not only can we provide high quality calibration gas, we also provide the knowledge and expertise of how and why to use calibration gas.

No other calibration gas manufacturer has this vast knowledge of portable gas monitors, indoor air quality monitors, fixed gas detection systems, continuous emission monitoring systems, infrared gas detection, process gas chromatographs, ion mobility spectrometers, flame ionization detectors, photo ionization detectors and other monitoring and detection technologies. So when it comes to calibration gas for gas detection technologies, call the experts at Gasco.

Founded in 1999, Gasco is a leading producer of precision calibration gas. Our products are exclusively sold through safety and equipment distributors worldwide. Gasco's superior industry knowledge (50 years of combined gas detection, and more than 80 years of combined analytical instrumentation and sample handing) has resulted in innovative technologies and the ability to create custom gas mixtures. This is precisely what led us to develop an advanced process to extend the reactive gas shelf life in our aluminum cylinders, allowing Gasco to deliver some of the longest warranties in the industry without compromising quality.

The Tech Air Companies are a great fit for Gasco's customers because both companies have a similar culture and a relentless focus on customer service instilled through generations of family ownership. Together we have access to all major product lines and many additional resources to help our customers succeed in the market.

After more than seven decades in the industry, we continue to maintain the highest standards so we can provide our customers with "Nothing But the Best" in experience, quality and reliability. We thank you for your business and look forward to serving you in the future.
