Aero Dyne H-E-P Turning Vanes are laboratory-tested and certified for performance.
Based on results from the ETL Testing Laboratories, Inc. Report no. 48037, Aero Dyne H-E-P Turning Vanes had lower sound power levels when compared to four other turning vane designs. Lower sound power levels will result in lower sound pressure levels (dB). Based on the same report, the H-E-P Turning Vane performed better or equal to a single-width radius elbow in 8 of the 16 tests.
Aero Dyne Turning Vanes resulted in much lower pressure loss (in WC) when compared to a single-width radius elbow. The H-E-P turning vane also resulted in lower pressure loss when compared to the other three double wall turning vane designs in the report.
Beware, depending on the fabrication method and steel gauge used to make other turning vanes, performance will vary. Turning vane performance may not be consistent with these test results.
Aero Dyne Turning Vanes & Rail are manufactured the same today as they were 50 years ago, so quality will never vary.
H-E-P Turning Vanes are engineered for performance. To avoid a costly replacement job, always require independent performance test data when specifying turning vanes and rail for your project.
