The Venturi variable air volume system can automatically balance the air volume of the pipeline andcontrol the speed of the frequency conversion fan in real time through the network to achieve the effect ofsafety and energy saving. The laboratory air supply system is linked with the room exhaust air. TheVenturi variable air volume system can automatically control the air volume of the air supply terminal, andshare the data to the exhaust system host through the network to ensure the number of air changeswhile keeping the laboratory at a stable load. Pressure or positive pressure state, quickly stabilize theroom pressure after the room personnel open the door to enter and exit
Therefore , Venturi variable air volume is widely used in various types of high-level chemical andbiological safety laboratories to precisely adjust the exhaust and appropriate air volume of the system
The system has the following characteristics：
1 . Strong pressure capacity : normal use between 150-750pa
2 . High control accuracy : + / -5% in the full range
3 . High-speed response : the response time is less than 1 second
4 . Convenient installation and debugging , maintenance-free
5 . Adjustment ratio : 20 : 1
6 . Anti-corrosion design of the whole valve body
7 . 5G big data manipulation
