Round Retrofit Terminal - RT-500

The Metalaire series RT-500 retrofit air terminals are designed to regulate the flow of conditioned air in single or dual duct air distribution systems. They can also be used to provide positive or negative pressures in laboratory flow hood applications. Series RT-500 is ready to be installed into existing duct-work in front of an old air terminal. The terminal unit features the proven, low leakage Series TH-500 air terminal damper.
