Silenced power ratings include this 3 dB reduction as well as the silencer attentuation. <br /> <br />Estimated Sound Pressure Levels Levels expressed in dB (pressure levels reference 2x10"1 microbar) <br /> <br />Directivity/Reflection Factor (Q) is 2, hemispherical radiation; Distance is 5 ft <br /> <br />This fan is not connected to any ducting. The Total Fan PoWer levels (after accounting for any inlet and/or <br />outlet silencer attenuation) are the basis for sound pressure level calculations. A-weighting is in use. <br /> <br />The estimated total fan sound pressure Ievet outside the fan is 92.3 dBA at 5.0 feet. <br /> <br />Your Representative: <br />AIR MOVING EQUIPMENT CO <br />8901 Jameel Suite 100 <br />HO}Jston, TX 77040 <br />Phone: (713) 46Ch3200 <br />Fax: (713) 460-3270 <br />E-Mail: Fax: (713) 460-3270 <br /> <br /> <br />AMCA Licensed for Air Pec1'ormanoe wittlOut <br />Appurtenances.
