Detailed Product Description

Introduction :
ASLI Variable Air Volume (VAV) terminal units are volume flow rate controller for supply air on variable air volume system. These units are designed to control the airflow rate of conditioned air into an occupied space in response to a control signal from thermostat or Building Automation System ( BAS ). The could be used in stand alone system, or interfaced with LONWORKS or BACnet.

ASLI VAV consist of a casing with circular inlet spigot, rectangular outlet connection with integral of fiberglass with black matt tissue for noise reduction, damper blade for air volume control and cross flow differential pressure sensor for measuring air volume.

ASLI VAV terminal units also incorporate control components, (VAV Controller actuator and transformer), which are factory fi0tted. ASLI in-house testing facility ensured that all boxes that come out from the factory are calibrated and tested to match the controller of individual size. This allow the terminals to monitor the desired flow rate, as dictated by the thermostat or BAS, and compensate instantly for any changes in supply air pressure that might tend to alter the supply air volume. Hence, the net result is a pressure independent variable air volume system.
