- Zero Air Gas Generators for Benchtop



Aadco manufactures zero air gas generators that house components capable of output volumes of 0-50 and 0-100 liters/minute; 0-20 and 0-30 Liters/minute and 0-1, 0-5 and 0-10 Liters/ minute respectively.

All of our zero air gas generators contain a purification reactor, input and output pressure gauges, 9-inch rotameter, output flow adjust valve—all components sized to the output flow requirements of the particular instrument. All of these instruments function exactly alike, differing only in power requirements, component sizing and cabinet dimensions.

The 737-12 bench-mounted zero air gas generators, with maximum output volume of 0-30 Liters/min. @ 0-50 psi, is available complete with compressor. The upper unit contains the purification system, with methane reactor and heat status indicator systems. A cycling heat indicator lamp gives assurance of temperature maintenance of the methane reactor at its preset operating temperature. Should the indicator lamp be suspect, front panel test jacks permit monitoring with a VOM for further verification of heat status. All fuses are front panel mounted for rapid and easy accessibility- All electrical controls are also located on the generator front panel, including the power switch to the compressor, even though the compressor is located in a separate unit. Electrical connection between the two units is made through a twist-lock umbilical which can also be connected to any AC outlet without special adapters.

The lower unit houses the compressor, mounted on a special vibration-isolation support. High volume cooling fans sustain a compatible internal temperature for optimum operation. Air enters through a strategically placed opening in the top of the unit, passes through a baffle system to eliminate sound from the unit, across the compressor and out through several openings located on the rear floor of the unit. Should there be a failure of the air circulating fans, an automatic thermal switch cuts off electrical power to the compressor, avoiding overheating and possible damage. This same thermal safety is incorporated in all compressors which AADCO supplies with zero air gas generators or as replacements. The complete interior of the unit is covered with high density sound absorptive insulating material, including the baffle system. Placement of the generator and compressor units may be side-by-side or one above the other, as shown. The high temperature connecting air hose which runs between the two units is of sufficient length to permit either configuration.

  • 0-50 and 0-100 liters/minute
  • 0-20 and 0-30 Liters/minute
  • 0-1, 0-5 and 0-10 Liters/ minute
