Specifying Aero Dyne H-E-P by name is critical. Simply referring to the industry sheet metal standard is risky.
The standard manual gives little detail about turning vanes and does not include performance information. Including performance requirements will encourage contractors to use Aero Dyne H-E-P versus fabricating turning vanes in their sheet metal shop.
Require independent performance testing if substitutions are submitted! To better understand the quality construction of our turning vanes, click here to get your Free Sample.
