Hvac Duct Turning Vanes

When airflow changes direction in a duct that lacks turning vanes the walls of the duct must absorb the sudden impact of the air and redirect it to the correct. 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.

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.

Hvac duct turning vanes.

Hollow turning vane and vane rail are designed to redirect the air through elbows and tees in the ductwork without significant loss of air pressure. Turning vane are manufactured from 26 gauge galvanized steel. The installation of turning vanes in hvac ductwork is perhaps one of the greatest sources of contention between mechanical contractors and hvac engineers. Turning vane and the accompanying rail are used in rectangular ductwork when a ninety degree bend is needed.

How to install a duct turning vane. 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. Assembled vane rail minimizes turbulence in the ductwork the vane rail has self aligning tabs for easy vane installation. Turbulence inside ductwork increases the costs of heating and cooling a home by reducing the efficiency of a forced air duct system.

They are used to promote a more uniform airflow and reduce pressure drop. Hvac turning vanes are c urved sheet metal fins placed in air conditioning duct work at a point where the duct changes direction typically a 90 degree turn. Fabricated with precision equipment to ensure consistent product quality the prorail hvac duct turning vane system results in precise vane alignment. The largest amount of.
