Features:
1. Intelligent adjustment of negative pressure, no manual adjustment (traditional adjustment is made by limiting valve and unstable)
2,15 liter air tank to ensure stable air pressure
3. The air pump does not need to work all the time. When the air pressure is insufficient, it will work automatically to replenish the air pressure
4. Stable air pressure can be provided to ensure the continuity of spray head drawing
5. In night mode, the air tank can be turned on at any time with air pressure
Working principle:
Users set pressure value, vacuum pump work, negative pressure sensor signal to the control panel, to achieve the set pressure value, the control panel to signal to the vacuum pump stop working, and when is lower than the set value, the vacuum pump will automatically start, keep the user setting of the negative pressure value. When the pressure is too large, negative pressure table gives the signal to the control panel, then two-way valve to start the deflated, ensure users to set pressure value.
