Seiho's Model NTX Surface Mounted TurboNozzle offers excellent architectural styling for directional control in supply applications. Designed specifically for a flush flange mounting to wall and ceiling construction, it provides an integral, readily-accessible, airflow adjustment in its installed position. The NTX differs from the NT in its mounting configuration and the nozzle position. The NTX uses a shallower flange and the nozzle protrudes from the flange. The heavy-gauge anodized, aluminum and stainless steel construction is corrosion-resistant for years of service. The aluminum finish integrates seamlessly with the many architectural finish systems.
