Hartzell 48” Industrial Belt-Drive Axial Fan

Model: 31-48-WP3 | Capacity: 49,000 CFM | Motor: 20 HP

Overview

Up for sale is a high-performance Hartzell Series 31 industrial axial ventilation fan. Widely recognized as the "gold standard" in industrial air movement, Hartzell fans are engineered for 24/7 continuous operation in demanding manufacturing environments. Delivering a massive 49,000 CFM, this unit is ideal for large-scale plant ventilation, heat exhaustion, or specialized process cooling.

Unlike standard ventilation fans, the Series 31 features a heavy-gauge, hot-rolled steel housing with continuous welds, ensuring maximum structural integrity and vibration resistance under high-velocity loads.

Key Sales Features
