The BOOSTAR series is equipped with a patent-pending second booster mechanism and a new process (3-tower PSA system) equipped with 3 suction towers to suppress pressure loss in the process, thereby producing low-pressure general-purpose factory air. It was born as a new concept nitrogen gas generator that can be used and can supply nitrogen gas that exceeds the raw material air pressure. BOOSTAR series, which manufactures nitrogen gas more easily, has solved the conventional problem of insufficient discharge pressure while using factory air, which has a high initial investment,maintenance, and energy-saving effect for the entire factory.
