Professional high-capacity oxygen generator designed for medical institutions requiring a high-pressure, high-flow oxygen supply. The BIOMED JAY-20 (4.0) delivers a continuous output of up to 20 liters per minute with an outlet pressure of 0.14–0.4 MPa (1.4–4 bar). This high-pressure capability allows it to be connected to anesthesia machines, ventilators, or small-scale central oxygen piping systems in clinics. Equipped with advanced PSA technology, a digital display for real-time monitoring, and a comprehensive safety alarm system for low oxygen purity and pressure fluctuations. Its robust, mobile design is ideal for operating rooms, intensive care units, and emergency departments.
