GP-500A Gas Purification System

GP-500A is a 30 CFM standalone, automatic, regenerating, dual column inert gas purification system designed to continuously recirculate process gas from a glovebox through a filter column containing a mixture of oxygen and moisture getters. This closed-loop filtration process can achieve an ultra-dry gas environment of about 1 ppm moisture and oxygen when integrated with typical Amada Weld Tech Benchmark® gloveboxes.

GP-500A Plus has a 3.1 inch touch screen LCD display with built-in shortcut function keys which allows single button filter column selection or regeneration.
Also available in single and dual column manual configurations, the GP-500A gas purification system’s modular, low profile design means it can be easily integrated into most gloveboxes on the market.

Specifically designed for ultra-dry nitrogen or compressed dry air (CDA) welding environments for hermetic sealing ...
