Sound Attenuation
The centrifugal fan design of the LSWB models operate at lower sound levels which make these units preferable for installations where noise is a concern.
For noise-sensitive applications, all LSWB models may be supplied with various stages of intake and/or discharge attenuation packages which greatly reduce
sound levels. Oversized fan motors may be required for many of these options in order to overcome the additional static pressure. Consult your local sales
representative for certified sound data for each sound attenuation option.
Inlet Attenuation
Reduces sound radiated through the air intakes. It consists of baffled panels that change the path of the air entry and capture the radiated noise thus
reducing the overall sound levels generated. Solid bottom panels are included with this option to force the inlet air through the attenuator.
Discharge Attenuation
The discharge attenuation hood features a straight-sided design with insulated baffles to reduce the overall sound levels of the discharge air. The
discharge attenuation incorporates a large access panel to allow entry to the drift eliminators and water distribution system. If a higher discharge
velocity is required with minimal sound attenuation, a tapered discharge hood is available.
