The Face Velocity method represents a complete engineered solution designed to accurately control face velocity through
measurement in the plane of the sash. Conforming to ASHRAE Standard 110, this method combines ultra low pressure
sensors, high accuracy air velocity sensors, BACnet DDC control, high speed electronic actuators, and precision control
dampers, to create a safe and energy efficient critically controlled environment.
The patented Auto-Flow Face Velocity method is the only method that actually offers complete closed loop control.
