Zero Air Medium

Supplies clean, dry, hydrocarbon-free air perfect for FIDs (Flame Ionization Detectors) and FPDs (Flame Photometric Detectors).

Utilising catalytic combustion technology the Apex Zero Air series provides clean hydrocarbon free air for the most demanding of applications. Once connected to a compressed air source the system has no moving parts and will provide no restriction to the air flow through the system with a minimised power requirement.


The generator is designed for constant use in laboratories and other demanding applications. The zero air generator has no mechanical parts and is easy to install and use. It uses catalytic combustion to remove hydrocarbons and can provide up to 40 litres of air per minute.

All the models in our range are small enough that they will easily sit on a workbench. The Zero Air series provides flexibility to match your system requirements. The Zero Air is a highly customisable product, we offer variable flow rates between 1 and 80 litres per minute. A compressor can also be integrated into the machine increasing its versatility.

Features and Benefits
  • Clean, dry, hydrocarbon-free air to less than 0.1 ppm 

  • 4 Standard models for flows up to 40 lpm. (higher flow models also available) 

  • Utilizes the newest catalyst technology for consistent purity and long life 

  • Unlike competitive models, does not require expensive catalyst changes 

  • Quick 3-minute start-up time and low power consumption 

  • Models available designed for 24/7 operation and near-zero maintenance 

  • Eliminates run-outs, heavy cylinders and never-ending gas costs

How it Works...

Compressed air is fed into the system through a filter [1] which removes particulates and bulk moisture via an auto drain. The air is then passed over a low power heater element [2] before coming into contact with the catalytic converter [3]. At this point, any hydrocarbons are combusted into trace levels of moisture and CO2. The hydrocarbon-free air is now passed through a cooler [4] for a return to ambient temperature and the outlet filter [5] removes any residual moisture.
