Overview

The SVAD‑ST diffuser is a 24 in. (600 mm) square ceiling‑mounted VAV diffuser equipped with a built‑in electric motor and DDC controller. Integrated temperature sensors enable both VAV cooling and VAV heating functions. Four blade dampers modulate airflow—opening and closing to deliver warm or cool air into the room in direct response to temperature conditions.

Room air is positively induced across the built‑in temperature sensor, or alternatively measured via a wall‑mounted thermostat, external sensor, or desktop remote sensor. This ensures accurate and responsive room temperature control in both cooling and heating modes.
