Type CG340 Air Regulator
The CG330/CG340 series of compressed gas filter regulators are specifically engineered to deliver accurate pressure control while ensuring near-zero atmospheric leakage under steady-state or dynamic flow conditions. This makes them ideal for applications involving inert gases, natural gases, and other medias that must comply with strict fugitive emissions regulations. Constructed from durable, high-quality materials, these regulators are built to provide reliable, long-lasting performance in demanding industrial environments. The CG330/CG340 series is designed for critical applications where eliminating gas leakage is a regulatory necessity, ensuring operational efficiency and environmental safety.
Type CG340 Regulator is designed to provide accurate, constant control under variable flow rates and supply pressures. Compact and lightweight housing allows this unit to be mounted in applications where space is limited. Its durable construction withstands long term installation in harsh environments.
