Variable Speed 50 Inch Greenhouse Cooling Fan Ventilation System
Variable Speed 50 Inch Greenhouse Cooling Fan Ventilation System Greenhouse ventilation system refers to a set of methods, equipment and technologies designed to control the environmental conditions inside greenhouses. These systems help farmers manage temperature, humidity and air quality to optimize plant growth. In fact, an effective ventilation system can have a huge impact on plant performance and product quality. EC (electronically commutated) motors directly drive the fan blades without intermediate transmission components such as belts or gears. They are essentially inner-rotor brushless DC motors integrated with digital control technology.

83% Energy-saving Corrosion-Resistant FRP Greenhouse Cooling Fan Ventilation System
Direct-drive EC fans offer the following advantages:
High overall efficiency: The EC motor itself is a highly efficient permanent magnet synchronous motor, typically achieving efficiencies of over 83%.
No transmission losses: Elimination of friction and energy loss associated with belt drives (which typically account for 5–15% efficiency loss).
Smart speed control: The EC motor drive and control system can precisely adjust motor speed based on actual demand (e.g., temperature or pressure feedback).
High control integration: Built-in intelligent controllers can directly receive commands via interfaces such as 0–10V signals, 4–20mA signals, Modbus, or BACnet, enabling seamless integration into Building Automation Systems (BAS) for precise air volume and static pressure control.
No belt maintenance required: Eliminates the need for periodic inspection, tensioning, and replacement of belts and pulleys.
Lower noise and vibration: Reduction of friction-induced noise and vibration caused by belt drives.
