High Performance Single Duct Series: TH-500 Deisgned to regulate the flow of conditioned air in single duct air distribution systems; feature low leakage single blade damper; available with electric/pneumatic controls	Low Profile Single Duct Series: TL-500 Series TL-500 Air Terminals are designed to regulate the flow of conditioned air in a single duct air distribution systems. They are available in a wide range of standard control sequences and work equally well in constant volume and variable volume systems. The maxium height of the TL series is 12 1/2"
Series Fan Powered Air Terminal Units Series: FCI-600 Series FCI-600 fan-powered terminal units are designed to provide superior comfort control zones with both heating and cooling requirements. The fan in a constant volume (or series) fan powered terminal, runs continuously during occupied hours. FCI is available with an optional ECM motor for improved energy efficiency and control.	High Performance Dual Duct Series: DH-500 Series DH-500 (patent pending) High Performance Dual Duct Air Terminals are designed to regulate the flow of conditioned air in dual duct air distribution systems. In a dual duct system, both heated and cooled air are provided to the air terminal and mixed to provide the desired discharge temperature. The DH-500 has been engineered to provide a 1:30 mixing ratio, the highest in the industry. They are available with a wide range of standard control sequences.
Low Profile Series Fan Powered Air Terminal Units Series: FCL-600 Series FCL-600 fan-powered terminal units are designined to provide superior comfort control to zones with both heating and cooling requirements. The fan is a constant volume (or series) fan powered terminal, runs continuously during occupied hours.	Parallel Fan Powered Air Terminal Units Series: FVI-500 Series FVL-500 fan-powered terminal units are designined to provide superior comfort control to zones with both heating and cooling requirements. The fan in a variable volume (or paralell) fan powered terminal, runs only upon requirements for heat.
Dual Duct Series: DD-500 Series DD-500 Dual Duct air terminals are designed to regulate the flow of conditioned air in dual duct air distribution systems. In a dual duct system, both heated and cooled air are provided to the air terminal and mixed to provide the desired discharge temperature. The DD-500 is available with a wide range of standard control sequences.	Square Retrofit and Exhaust Boxes Series: SR-500 The METALAIRE® Series SR-500 is retrofit product designed to fit into existing low pressure square or rectangular duct system. The height of the installation plate varies with the duct height.
Round Retrofit Series: RT-500 Series RT-500 Retrofit Air Terminals are designed to regulate the flow of conditioned air in single or dual duct air distribution systems are also used to provide positive or negative pressures in laboratory flow hood applications	Retrofit Terminal Series: RA-500 Series RA retrofit assemblies are customized retrofit valves designed to slip into existing mechanically regulated single or dual duct terminals to convert to convert to variable volume operation
Bypass Terminal Series: BP-500 Series BP-500 Bypass Air Terminals are designed to achieve VAV delivery of conditioned air to a room in single duct, constant volume air distribution systems	Low Profile Parallel Fan Powered Air Terminal Unit Series: FVL-600 The FVL-600 Parallel Fan Powered Terminal Unit is designed to provide superior comfort control to zones with both heating and cooling requirements throughout the year.
Factory-Supplied DDC Controls Series: DDC The DDC controllers being offered include both a BACnet and LON® option. This option provides VAV controls that can easily be integrated into the building operating system at a savings in time and labor.
