Pioneering CO2  Purity and Cylinder Innovation in China

Our Story:

Populargas was founded in 2012 with a straightforward goal: manufacture CO₂ cylinders that meet every requirement, every time. Populargas is the brand of Populargas Industrial Technology Co., Ltd., based in Nanjing, China. Our engineering and quality teams in Nanjing have refined the steel selection, filling process, leak-testing routine, and surface protection to deliver safe, consistent performance in real-world use.

Our company is guided by Chairman Chen Liwei, COO Anya Sharma, and Chief Operations Technologist Graham Davies a cross-border leadership team combining global industry experience with advanced Chinese manufacturing capability. Their focus has been the same from the beginning: safety, compliance, and long-term customer success.

Over more than a decade of development, Populargas has grown from a local manufacturer into a trusted global supplier, supporting partners across the USA, Europe, and South America. Most of our customers stay with us for many years because they rely on manufacturing stability and honest quality control we don’t cut corners.

Our cylinders range from 8g to 110g and support a wide range of industries: airguns, beverage carbonation, home appliances, outdoor equipment, life-saving tools, and commercial pressure systems. No matter the application, users depend on a stable pressure response, precise filling, and worry-free handling.

Every CO2 batch is supported by official SDS documentation and produced using advanced purification and filtration systems that ensure clean gas characteristics and consistent performance. Our internal testing follows internationally recognized guidelines for safety, chemistry, and transport compliance.

We continue to invest in research, automation, and specialized customization so our customers can deliver better products under their own brands.
