Overview
The Exhaust fan Max 72'' is a heavy-duty, high-volume ventilation unit engineered for rapid air exchange in agricultural buildings (livestock houses, poultry houses, greenhouses). Its beltless direct-drive design removes belt maintenance and improves uptime. The integrated Variable Frequency Drive paired with a motor exceeding IE5 efficiency delivers precise speed control and energy savings. Composite fiberglass-reinforced blades and a corrosion-resistant housing are specified for humid, corrosive farm environments. IP66-rated enclosures protect the motor and connections. Soft start/stop reduces mechanical stress. Supports automation via 0-10V or Modbus for seamless climate-control integration.
