The PRICE AFSD (Airflow Sensing Device) is a flow measuring station combined with an adjustable damper whereby the air volume can be adjusted. The SP300 multi-point sensor ensures accurate pressure measurement, allowing the balancer to monitor the velocity pressure in the duct. The integral manually operated damper with quarter-lock allows for adjustment until the desired flow rate is obtained. A label on the side provides indication of the airflow for a given velocity pressure. The AFSD is specifically designed to operate with displacement ventilation systems to help balance downstream pressure and help in supplying optimum flow rate to the diffuser.

• SP300 multi-point flow sensor designed to maintain control accuracy independent of field installation conditions.
• Gauge taps for flow measurement and balancing.
• Inlet and outlet connection bead offers a means for secure flex duct connections.
