DIGITAL air on demand

Digital Red Lion Fan Speed Controller


Our Digital Air-On-Demand is ONLY available in AC.


The Red Lion 4.3" CR1000 Human-Machine Interface (HMI) is utilised by MAFI to control the operation of all VSD's from a single panel.


The CR1000 HMI module includes a full-colour 4.3" touch-screen panel with 2 serial ports, 1 Ethernet port and an SD port. The Red Lion system provides real-time feedback on the performance of the VSDs, allowing the user to adjust the fan's speed to optimise engine room ventilation.


Additionally, the Red Lion system has a sleek, modern look that is not out of place on the most luxurious of control panels.
