Dayton centrifugal inline duct blowers are used for clean air applications, such as intake, exhaust and return air. These units feature 1/2 inch internal fibreglass insulation to provide sound attenuation by dampening noise from HVAC systems and also control condensation for preventing rusting of components when used in cooling applications. They come integrated with access panels that allow convenient motor & drive installation and offer ease in servicing from either side of the cabinet. All units are steel constructed with green baked enamel finish for withstanding harshest environments and are available in blower speeds ranging from 384 to 1396 rpm.
