Specialty Gas Regulators & Accessories
Genstar Technologies Inc. is a global leader in gas flow control systems, serving industrial, specialty gas, and medical sectors. The company focuses on high-quality, value-added products and services, adhering to ISO 9001:2001, ISO13485, and API certifications, ensuring compliance with international standards like UL, CE, and SEMI.
The facility is equipped with advanced CNC machines, electro-polishing equipment, and precision automated orbital welding systems. Ultra High Purity (UHP) products are manufactured in class 10/100/1000 clean rooms, undergoing precision machining, surface finishing, and vacuum drying to ensure the highest quality.
Regulators are made from high-strength, corrosion-resistant materials, ensuring high accuracy and stability. They feature metal-to-metal, leak-proof seals and are designed to withstand temperature and vibration fluctuations. Multiple connection standards are supported, including CGA, BSP, DIN, JIS, and GB.
Single-Stage Regulators reduce pressure in one step, showing a slight increase in delivery pressure as cylinder pressure falls. Dual-Stage Regulators maintain constant delivery pressure by reducing pressure in two stages, offering greater accuracy. High Purity applications require diffusion-resistant components, typically using stainless steel diaphragms to prevent impurity contamination.
