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.
