The quiet model MB ventilation fan has been specifically designed for use in industrial metal buildings and low initial cost, with permanently lubricated and sealed bearings that make the fan exceptionally long-lasting. Metal building fans also feature aluminum shutters with reinforced interlocking blades. The velocity of the air over the motor dissipates heat, which increases horsepower. The speed of most metal building fans can be adjusted using variable pitch motor pulleys.
The metal building fan design allows for more versatility of use in all commercial and industrial applications where a complete fan package is desired. These complete packages greatly simplify the specification and use of ventilation equipment in commercial and industrial metal buildings.
Metal building fan packages are shipped completely assembled and each package includes fan, shutter, guard and housing for fast and simple ventilation installation. Additionally, inlet or discharge hoods and spark-resistant construction may be purchased.
