Syner-G S-25 Welding Gas Regulator

Lower Operating Costs

Perfect Even Flow for Less Waste and Improved Quality 

Great progress has been made over the last several years in welding power supplies, weld wire and welding gases, all with the view to increase performance, improve weld quality and to save you money. Syner-G by RoboVent is designed to do all of this and take you one step further towards a perfect weld.

The Syner-G S-25 welding gas regulator is on the cutting edge of process gas flow control. The typical gas regulator of the past controls pressure only, but does not properly control the flow. The S-25 precisely controls both pressure and flow with a proprietary mechanism, delivering steady, even flow throughout the complete flow cycle, right from the start, and then throughout the process. This gives you control of the actual gas being used, not just the amount of pressure being put on a spring inside the regulator.

Built for quality

We build safety, energy savings and efficiency into every piece of equipment we make.


Lower Operating Costs

We’re always looking for ways to reduce energy use, such as automated systems to ensure collectors run only when they need to. Additionally, our filters and equipment have been engineered to maximize filter life and reduce operating costs.


Superior Safety and Risk Reduction

Safety features like our Delta3 spark arrestor and the Supprex-200 fire suppression system reduce the risk of fires in your ductwork and filtration equipment to protect your plant and your employees.


Easy Maintenance

Longer lasting filters are just the start. Our equipment is built to reduce the maintenance burden on your staff. With the ePad Control Panel, you get an easy-to-use control system right at your fingertips to help monitor equipment performance and diagnose needed maintenance.
