Features :
1. the design of the machine is easy to fail, and the failure rate is low.

2. The closed design can prevent the dissipation of solvents and avoid the pollution in the container caused by the wetting, which can save about 25% of the waste of the water.

3. The process of not needing to be dipped in medicinal water can improve the work efficiency by more than 10%, and there is sufficient self-examination time in the operation.

4.The air pressure of pedal opening and pressure pipe opening must be maintained at about 4KG/cm².

5. The software management within the shutdown shall be replaced once a month to avoid water leakage caused by damage, and shall be maintained on a monthly basis.

6. JW-302 is equipped with a adjustable pneumatic mixer, which can automatically mix the additives in the container to avoid the phenomenon of sedimentation and uneven moisture.

7. If trichlorotrimeric acid (B powder) strong oxidant is added to the solution, it needs to be used within the effective time (2-4 hours), and it should be noted that the speed of the mixer must be adjusted slowly when using, and B powder is easy to adhere to the wall of the water tank and pipe, and it must be cleaned every day.
