The Pure Air Generator uses tha ambient air to provide high pressure pure dry air for re-filling high pressure vessels used in optronic systems equipped with Joule Thomson minicoolers.

The Portable Pure Air Generator is used to re-fill high Pressure bottles with pure gas, for Joule Thomson cooling. It is qualified by the french army for the MILAN system with MIRA camera. The Pure Air Generator complies with the latest European high pressure regulations.

Design Features

• Four-stroke Bernard engine equipped with an electrical starter and a manual starting device.
• Electromagnetic coupling for engaging or disengaging the comrpessor with no need to stop the engine.
• A.C. generator that powers the units electrical equipment.
• Three stage compressor
• Self-regenerated pre-drier, located at the outlet of the 3^rd compressor stage.
• CO₂ filter.
• Drier
