Glass plant fans are specialized blowers used for furnace exhaust, annealing lehrs, and cooling sections within glass manufacturing facilities. They operate at air temperatures up to 500 °C and resist corrosive silicate fumes.
Constructed from high-temperature alloys and lined with ceramic coatings, these axial or centrifugal fans deliver 10,000–150,000 CFM at pressures to 8 kPa. Dynamic balancing and refractory-cooled bearings ensure durability under thermal cycling.
Variable frequency drives provide temperature-responsive speed control, maintaining consistent draft and preventing furnace backpressure. Split housings for impeller access and external lubrication fittings reduce downtime. Glass plant fans are critical for production efficiency, product quality, and workplace safety.
