Controllers

The TruFlow demand ventilation controller is the cornerstone of our energy-efficient ventilation systems. Engineered and manufactured by Spring Air Systems, it comes in models designed for different kitchen sizes, appliance line-ups, energy savings goals and budgets. The TruFlow constantly monitors and calibrates exhaust air to match appliances in use, enabling exhaust hoods and fans, volume dampers and supply air units to work perfectly in unison with one another while maximizing energy efficiency.

We also offer a variety of other controllers with more basic functions, which manage individual ventilation components.
