Fume hood variable air volume control system adopts a controller that integrates a fast actuator and a
controller. It monitors the opening of the fume hood window through displacement sensors and quickly
adjusts the opening of the air valve to achieve a constant air velocity on the control surface. It is suitable
for fume hood systems using butterfly valves or Venturi valves. When the exhaust volume is set below
the safe value, the system will activate the built-in sound and light alarm to provide maximum safety
protection for laboratory staff. Suitable for various types of experimental fume hoods and exhaust equipment.
There are multiple working mode settings that can meet the different needs of customers.
