NOTES:
➀
All data is based on the air diffusion council guidelines.
➁
Throw data is based on 75 FPM Terminal Velocities using isothermal air.
➂
Throw is based on diffuser blades being directed in a straight pattern.
➃
Actual noise levels may vary due to duct design and do not include transmitted unit noise.
Adequate duct attenuation must be provided to reduce sound output from the unit.
