The Belt Drive Double Inlet Fan is a versatile centrifugal ventilation solution designed for supply and extract applications across all market sectors. Available with both forward and backward curved impellers, the range offers flexibility to suit varying airflow and pressure requirements. Its belt drive configuration positions the motor outside of the airstream in most applications, reducing direct exposure to heat and contaminants. This design enhances durability, improves service life, and makes the unit particularly well suited to demanding or aggressive operating environments.
Product Information
The Belt Drive Double Inlet Fan range is engineered to deliver reliable airflow performance across a broad spectrum of ventilation requirements. Its double inlet centrifugal design supports efficient air movement, while the option of forward or backward curved impellers allows system designers to optimise performance based on pressure, efficiency, and application demands.
A key advantage of the belt drive arrangement is the motor positioning. In most configurations, the motor sits outside of the airstream, protecting it from heat, moisture, dust, and airborne contaminants. This significantly extends motor life and improves reliability in environments where elevated temperatures or aggressive conditions are present.
Market & Application Suitability
Suitable for commercial, industrial, and specialist ventilation systems, the range performs effectively in manufacturing facilities, plant rooms, commercial buildings, workshops, and process environments. Designed for both supply and extract air applications, it provides a dependable solution for engineers and contractors seeking flexible, long-life centrifugal fan performance.
