ZeroAir Generator

The Zero Air Generator series are systems which replace the use of inconvenient high pressure gas cylinders as a source of hydrocarbon-free air.

The elimination of gas cylinders reduces annual operating costs of managing them and reduces the risk of possible injury to workers.

Zero Air Generator may be used as a source of fuel air for Flame Ionization Detectors (FID’s) or as a zero reference for any instrument which measures hydrocarbon concentration.

The zero air generator will remove HC pollutants to less than 0.05 ppm.

This system is engineered to be easy to install and requires only minimal annual maintenance.

Increased laboratory efficiency

A constant, uninterrupted gas supply of guaranteed purity eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.

Improved economy

Pure nitrogen gas produced as standard

Improved safety

Nitrogen produced at low pressure and ambient temperature removes the need for high pressure cylinders

Security of supply

Integral oil free air compressor as an option guarantees continuous gas supply, independent of in house compressed air supply

Simple installation

Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere
