TURNING VANES 101
Consulting engineers have been specifying Aero/Dyne turning vanes by name for more than 40 years, because of its unmatched reliability and performance.

Did you know that if you don't specify an engineered turning vane product, they usually are made by contractors in their sheet metal shops?  The problem with this is they have questionable pressure drops and noise levels, collect lint and dust, and can become detached from their low-cost dimple supports. 

AERO-DYNE VANES
Aero-dyne HEP vanes are aerodynamically design and laboratory tested and certified.   You can count on the pressure drop, sound, and structural performance of these vanes.  The design geometry adapts perfectly to all duct sizes, eliminating the need for different vane sizes in the system.

Fastener is simply driven thru the pre-punched side rail slot and into the continuous tubular channel in the vane. This exclusive method provides rigid, permanently rattle-proof assemblies at its lowest possible cost.

H-E-P turning vanes are designed specifically for use in rectangular duct turns with velocities between 1500 and 2500 fpm

SUMMARY OF ENGINEERING BENEFITS

• True airfoil contour reduces pressure loss to the lowest attainable level
• Formed from ONE piece of galvanized hot dipped prime carbon steel
• Eliminates breakaway of flow from surface on suction side
• Generated sound power level does not exceed 54 decibels in band 4 at 2000 fpm (24"x24" duct size) - as required by engineers
• Design provides a permanent rattle proof assembly
• Provides a Cleaner Duct (IAQ) environment, because of it's Smoothly-rounded entry nose with extended trailing edge, resulting in no collection of dirt or debris.
• Extended training edge maintains smooth airflow with much less turbulence
• Provides velocity distribution of greatest possible uniformity
• Maintains a consistently high-degree of deflection accuracy, and continuous internal tubes provide a stiffening and rigidity to the section which prevents distortion and fluttering under airflow.
• Design geometry adapts perfectly to all duct sizes
• When installed before and after fans or air handlers, they reduce turbulence and backpressure, reducing system effect.
• Positive Assembly - secure for a perfect stay put-fit.  No rattle – No detaching
• Easy & Quick Assembly – Fastener is simply driven thru a pre-punched side rail slot and into the continuous tubular channel in vane, this exclusive method provides a rigid permanently rattle proof assembly.

The H-E-P Airfoil Design gives superior energy savings, low impact losses, low pressure drop, with dramatically reduced sound power levels

No other product on the market today provides comparable quality, structural integrity and performance.
