DWDI (Double Width Double Inlet) Fans are high-efficiency centrifugal fans designed for applications requiring large volumes of airflow at lower pressures. With two inlets drawing air into the impeller, these fans maximize air movement efficiency, making them ideal for HVAC systems, industrial ventilation, and air handling units. Their robust design ensures consistent performance, effectively managing air circulation, dust extraction, and cooling processes in factories, warehouses, and commercial buildings.


At Sigrist Design, our custom-engineered DWDI fans are built for durability, low-noise operation, and energy efficiency. Available in various sizes and configurations, they can be tailored to meet specific airflow and pressure requirements. Designed for long-term reliability, these fans help businesses optimize ventilation performance while reducing operational costs, ensuring compliance with Australian building and workplace safety standardsNeed help?
