Highly Efficient Backward Curved Fans
Backward curved fans offer strong performance capabilities with minimal energy costs, making them high value components to many centrifugal fan and blower applications. The backward curved blade profile empowers these fans to move high volumes of air at high static pressures with high static efficiencies. While used in mostly clean air applications, backward curved fans can also handle light dust and particulate.
Backward Curved Fan Product Description
AirPro’s backward curved technology is our most efficient offering and includes three fan models and a newly-expanded range of sizes from 150-890. The model variations provide solutions for high, medium, and low air volume applications.
BCHS – this model provides the highest air volume out of the backward curved options. It’s primarily used for induced draft applications, though it offers a great forced draft solution as well.
BCMS – designed for medium air volume levels, our BCMS boasts static efficiencies above 80% for both induced and forced draft air requirements.
BCLS – with a narrow wheel and housing, the BCLS moves lower air volumes at higher static pressures. It’s most commonly used with induced draft applications requiring combustion air.
The best model for your application depends on the air volume and static pressure your system requires. Our team of application engineers can review your system requirements and select the best option for you.
We build all three backward curved fan models with heavy industrial strength and robust construction. Our customers depend on these fans to keep them in operation. We understand that reliability is critical, and that reality drives our engineering and manufacturing standards.
