Series 58E

Series 58E Fiberglass Hooded Ventilator — Belt Drive | Hartzell Air Movement
Fiberglass Belt Drive Hooded Ventilator

The Series 58E Fiberglass Hooded Ventilator’s design provides complete protection from the elements for exhaust operation. The unit’s belt drive configuration and exterior motor mounting make it the logical choice where corrosive elements exist and protection from weather is essential. Standard sizes are 12 through 60". A heavy-duty fiberglass panel provides a convenient method of curb mounting.

The fiberglass hood attaches to and is removable from the fan casing. Sizes through 32" are one-piece construction; sizes 36 through 60" are two-piece construction. Hinged construction is also available, providing access to the ventilator without complete removal of the hood.

The exterior-mounted motor is out of the airstream. The propeller shaft rotates in two heavy-duty bearings mounted on fiberglass supports taped to the inner shell with “T” reinforcements.

Belts, bearings, sheaves and the shaft are enclosed and protected from the airstream. The drive compartment is located on the negative pressure (suction) side of the propeller, drawing ambient air from outside the fan in and over the belts and bearings, ensuring a contaminant-free drive compartment.

The Series 58E (exhauster) can be supplied in Series 58I (intake) configuration. Contact the factory for additional information.
