Unequal Elbows

Aero Dyne Turning Vanes Installation in Unequal Elbows

Aero Dyne Turning Vanes & Rail adapt perfectly to all duct sizes, eliminating the need for two different vane sizes in the system.  An entire assembly of H-E-P Turning Vanes can be adjusted easily and precisely to the proper angle of attack, regardless of the inlet and outlet dimensions of the elbow.

A narrow strip (approx. 3/4 inch) is sheared from the center of both top and bottom side rail pieces.  Vanes are attached to them by the usual method of driving fasteners through the slots.  All of the vanes in the assembly then move together as the correct alignment is made for the elbow, maintaining the leading and trailing edges in an exactly parallel relationship.

No other product provides this capability.
