Type CG330/CG340 Gas Regulators Cut Emissions in Gas Applications

April 24, 2025
ControlAir’s Type CG330/CG340 Gas Regulators minimize atmospheric leakage for air, inert gas, and sweet natural gas.

Types CG330 and CG340 compressed gas filter regulators provide accurate pressure control with near-zero atmospheric leakage in steady-state and dynamic conditions. These regulators are suitable for use with air, inert gases, and sweet natural gas across a wide temperature range.

The CG330 includes enhanced filtration capabilities with a standard 40-µm filter and an optional 5-µm upgrade, as well as an automatic drain to reduce corrosion and maintenance needs.

The CG340 offers a compact and lightweight design for pressure regulation in space-constrained applications.

Both models are available in 1/4 and 1/2 in NPT port sizes with output pressure ranges of 0 to 30, 0 to 60, and 0 to 120 psi.

Features:

  • Near-zero (less than 0.1 scfh (0.05 Nl/min)) atmospheric leakage
  • Die-cast aluminum alloy body with iridite and baked epoxy finish
  • 1/4 and 1/2 in NPT port sizes
  • Output pressure ranges: 0 to 30, 0 to 60, 0 to 120 psi
  • CG330: 40-µm filter standard; optional 5-µm filter
  • CG330: Automatic drain system to minimize corrosion
  • CG340: Compact, lightweight design
  • Operates from 0 to 160°F (manual drain) or 32 to 160°F (automatic drain) (-18 to 71°C or 0 to 71°C)
  • Compatible with air, inert gas, and sweet natural gas
  • Suitable for use in oil & gas, chemical processing, and other emission-sensitive industrial environments
