JetVent Fans, Controllers, and Sensors

The preconfigured Digital JetVent Control Center responds to varying levels of pollutants, as reported by the sensors, and varies the operating speed of the fan (s), and therefore the ventilation rate, by zone. This controller can also vary the speed of supply and exhaust fans and integrate their operation with overall ventilation requirements ...

Benefits of Jet Fan Systems: Space saving – jet fan systems are more discreet and take up considerably less room than ducted ones. Energy saving – they are often combined with Carbon Monoxide (CO) detection to initiate CO control, this ensures that fans are precisely controlled to dilute pollution without running unnecessarily.


Automatic fan speed control circuit by Arduino

Speed of fan can be varied by changing the input supply, if w need to change the fan speed depends on temperature changes means we can implement the following application note with Arduino and temperature sensor LM 35. Circuit diagram. Construction and Working


Designing a JetVent Parking Garage Ventilation System

CO sensors will be more effective if placed in areas where CO levels are likely to be high. For example, do not place sensors adjacent to the fresh air intake. If JetVent fans are placed in each traffic lane of the garage, and Recommended Fan spacing is followed, the plan outlined above can be achieved by using one CO sensor per fan, and ...


Car park ventilation system with jet fans Industrial fans

Jet fans can be arranged in groups, controlled by corresponding groups of CO or CH4 sensors. The quantity of air to be moved can thus be regulated in response to requirements. As this is achieved at relatively low air velocities, energy is saved.

JetVent Fans

The Control Center communicates with JetVent fans, integrated sensors, supply fans and exhaust fans to dynamically control the rate of ventilation according to the CO or NO 2 pollutant levels, or temperature in the space. This control system costs less to install, is simple to commission, and easy to monitor.
