Hvac Duct Turning Vanes

Fabricated with precision equipment to ensure consistent product quality the prorail hvac duct turning vane system results in precise vane alignment.

Hvac duct turning vanes.

Turning vanes inside of large fire resistance rated durasteel pressurisation ductwork turning vane close up hvac turning vanes are sheet metal devices inside of mechanical ductwork used to smoothly direct air inside a duct where there is a change in direction by reducing resistance and turbulence. This assembly is used in a square throat elbow in lieu of a radius elbow which can be more difficult and time consuming to build. Turning vane and the accompanying rail are used in rectangular ductwork when a ninety degree bend is needed. Assembled vane rail minimizes turbulence in the ductwork the vane rail has self aligning tabs for easy vane installation.

Turning vane are manufactured from 26 gauge galvanized steel. Because many mechanical contractors believe that turning vanes can cause the ductwork to become less efficient by increasing the pressure drop in the system as well as adding time and expense. The installation of turning vanes in hvac ductwork is perhaps one of the greatest sources of contention between mechanical contractors and hvac engineers. Turbulence inside ductwork increases the costs of heating and cooling a home by reducing the efficiency of a forced air duct system.

The largest amount of. How to install a duct turning vane. The prorail hvac duct turning vanes and rail system provide a self aligning easy means of securing hvac turning vanes that direct airflow around mitered elbows in hvac ducts. They are used to promote a more uniform airflow and reduce pressure drop.
