DESCRIPTION

   Turning vanes are non-adjustable 90˚ air turns designed to reduce the pressure loss in square duct elbows.

   The galvanized steel blades are double walled and formed to assure that any point on one blaed is

   equiidistant from the same point on an adjacent blade.

   This precise blade shape maiintains constant duct area and assurcs constant air velocity around the elbow

   eliminates loss due to velocity changes. and results in low friction loss.

   The blade is rigid and eliminates the need for cross bracing or reinforcing rods. Roll-formed from a single

   sheet of metal, surfaces and edges are smooth and free from edge friction and blade turbulence.

   Blades assemble over precision-formed  tenons on the side-picccs, which insures precise blade alignment,

   proper spacing, and predictable engineering performaance.

   They are cut to size and assembled in the field. Assembly is simplle and economical since no special tools

   and  no fasteners are needed. The complete unit is screwed or riveted into the duct elbow.
