Dimensions: Diameter 360mm, length 600mm large transition cabin, piston valve, the transition cabin has a movable tray, polished, an additional small transition cabin is set inside the box, with specifications of diameter 150mm, length 300mm, manually controlled for vacuuming and replenishing air.

2.3. Tray: Can freely extend (The large transition compartment is equipped with)

2.4. Vacuum Degree ≤ 1 bar (Both large and small right transition compartments are required to be able to vacuum and display vacuum values)

3. Control System

3.1. Method: Includes self-diagnosis, power-off self-starting features, pressure control and adaptive functions. Automatic control, cycle control, password protection, vacuum chamber control are displayed by LCD. Unit control uses Siemens PLC touch screen.

3.2. Pressure Control: Controls the pressure of the box and the transition cabin at a certain set value.

a) Users can set the working pressure range between +12 and -12 mbars, with an accuracy of ±1 Pa. The PLC will automatically regulate the pressure of the box within the set range. The default value of the working pressure range is -1 to +3 mbars.

b) When the box pressure is greater than 12 mbars, the PLC automatically opens the safety valve to relieve pressure, protecting gloves, equipment and materials inside the box.

c) Use foot pedal switches to make fine adjustments to the box pressure.

3.3. Foot Pedal: Can control the pressure of the glove box and facilitate operation.
4. Circulatory System (including purification and regeneration system)

4.1. Purification materials from BASF of Germany and UOP of the United States, valves from Baode of Germany. The main system is designed with modular integration, featuring fully automatic electronic control, pneumatic valves, PLC control, circuits, circulation pumps, purification units, and displays integrated into a separate purification unit, forming a compact and minimalist system.

4.2. Control: Water and oxygen are controlled at less than 1PPm.
