Highly Efficient Backward Inclined Fans
The backward inclined fan, which is also referred to as a backward inclined blower, is highly efficient due to its simple, flat, backward inclined blades that minimize interference with airflow as air moves through the fan. It also offers lower sound levels and energy costs than many other fan types and includes a non-overloading horsepower design for low-pressure applications. Additionally, this fan is suited for clean air and/or high-temperature applications.
Backward Inclined Fan Description
BIHS (Backward Inclined, High volume, Single width) – the backward inclined blower moves high volumes of clean air at lower static pressures. It is available in belt-driven, direct-driven, and direct-coupled arrangements with varying impeller and housing widths.
BIHD (Backward Inclined, High volume, Double width) – this backward inclined fan model is similar to the BIHS except that the impeller and housing are double the width. This gives the BIHD a higher air flow capacity.
AirPro designs the backward inclined fan impellers with a focus on high operating efficiency, and we never compromise on high mechanical strength. Our robust design and construction features continue to serve our customers with reliable fan performance.
