Centrifugal Blowers are used for general HVAC and industrial applications where large volumes of air are required at low, moderate or high pressures. General HVAC fans are used for the exhaust, supply, and return air of many types of buildings. Industrial duty fans are used for industrial processes, filtration systems, air pollution control, and fume exhaust. May be constructed forward curved, backward inclined, or with a radial blade or airfoil wheel, depending on the application. Construction is typically steel, aluminum or stainless steel, depending on the model chosen. We can design many custom features or options to suit your project requirements.
