Zero air generator

Zero air generation system for calibration. Prepared per se for use in the entire range of automatic atmospheric pollutant analysers.

Technical specifications

  • Composed of two separate and interconnected modules:
  • Compressor and reserve tank
  • Purification module for the removal of contaminants.
  • Its characteristics are as follows:
  • NO and NOX content : < ppb.
  • SO2 content : < 1 ppb.
  • H2S content : < 1 ppb.
  • O3 content : < 1 ppb.
  • CO content : <0,1 ppm.
  • Methane and hydrocarbon content : <0,1 ppm.
  • Water vapor is removed by compression and steam filter. The dew point is slightly below 0°C.
  • The compressor unit stops automatically when the maximum regulated pressure is reached.
  • The generator provides up to 10 lpm of clean air, at an adjustable output pressure up to 30 PSI, constantly and continuously.
  • The compressor is mounted on shock-absorbing and anti-vibration supports, above the air reserve cylinder.
  • The contaminant removal module is mounted in a 19″ rack box , 4u. and has indicators for pressure, flow, operation and connection of the catalytic ovens.
  • Weight: compressor 24Kg and purifier 24 Kg.

Applications

  • It is a source of dry, clean air for calibrators, purge air for permeation tube ovens or air for FID analysers.
  • They can be used in a variety of source, zero and flue gas analysis applications for hydrocarbon and total analysers as a dilution or calibration gas for gas detectors.
