Registers for spiral ducts

Transcription

1 Registers for spiral ducts RGS-3 5 The RGS-3 is a supply/return register with adjustable double deflection blades and a volume damper designed specifically for direct mounting on a spiral duct. The use of rectangular register taps are not required. The register is designed in such a way that the flanges always meet flush to the duct regardless of the duct diameter. It also comes equipped with end caps and a gasketing material installed around the neck of the register. This prevents air leakage. RGS-3 is manufactured from galvanized sheet steel and is assembled without the use of welding. This allows the register to be used without further surface treatment and gives it the same finish as the duct. Materials and finish: Register: galvanized sheet steel Damper: electro-galvanized sheet steel Maintenance The grille should be removed to gain access to the duct.

Position the RGS-3 register in the opening, making certain that the gasket material remains in place. Check that register has been installed correctly in relation to the direction of air flow. n = number of measurepoints n n=1 V 0 = n V n Dim. n 13" 2 17" 3 21" 3 25" 4 33" 5 41" 7 49" 7 Secure the RGS-3 with screws (provided. djust vanes as necessary.
