SureFlow Fume Hood Face Velocity Controller 8650

[Discontinued]

Product Details

This unit has been discontinued as of September 1, 2010.

TSI's SureFlow™ Model 8650 SureFlow Fume Hood Face Velocity Controller is designed to control your fume hoods to a constant face velocity.

By providing a constant face velocity, the SureFlow will enhance the safety and reduce the energy costs of a fume hood. Designing around these reduced flows allows HVAC equipment such as fans and chillers to be downsized. SureFlow provides opportunities for energy savings, lower fan brake horsepower, smaller chillers and lower duct work cost by reducing the volume of air exhausted from a hood when the sash is not fully open.

The 8650 provides a closed-loop VAV control system for proper lab hood containment. The SureFlow assures safety by responding quickly during sash movement, or to disturbances within the sash plane, to maintain a constant face velocity and contain hazardous chemicals.

The 8650 easily integrates to the building management system using either alarm relays or digital communications. The open MODBUS protocol is supported by the 8650. Because SureFlow fume hood controls continuously measure average face velocity, they meet industry requirements for air flow monitors.
