The Pure Air generator eliminates the need for costly, inconvenient high pressure cylinders in the laboratory.
Including an integral oil free air compressor, the Pure Air generator delivers a continuous stream of pure air gas with HCs content <0.01ppm, ideal for applications, such as, GC-FID.

Air is produced by pressure swing adsorption (PSA) using two activated alumina columns to remove water, hydrocarbon non CH4 and particles from compressed air.

The Generator is controlled using the latest in HMI touch screen technology to display the process in real time, inlet/outlet pressures.

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

Improve economy
Pure air gas produced as standard

Improved safety
Purified air produced at low pressure and ambient temperature removes the need for high pressure cylinders

Security of supply
Do not requires external compressed air supply; integral oil free air compressor guarantees continuous gas supply

Simple installation
Gas generators can be installed in the laboratory eliminating the need for long gas lines from cylinders secured elsewhere
