AirPro Fan & Blower

Main Equipment

Backward Curved Fan

AirPro’s backward curved centrifugal fans and blowers deliver powerful performance with low energy consumption, making them a smart choice for a wide range of industrial applications.

Engineered with a backward-curved blade design, these fans efficiently move high air volumes at high static pressures while maintaining exceptional static efficiency. Ideal for clean air systems, they can also handle light dust and particulate, offering flexibility across process ventilation, combustion air, and general industrial airflow applications.

The curved blade profile is key to its performance. It minimizes turbulence and maximizes energy efficiency, making backward curved fans ideal for moving large volumes of air at higher static pressures. This combination of high efficiency and robust performance makes them a go-to choice for demanding industrial applications where consistent airflow is critical.

Radial Tipped Fans

The radial tipped fan delivers high static efficiency while resisting material buildup on the wheel/impeller. A radial tipped blade design keeps dust and other particulates moving through the wheel to exit the fan. Additionally, radial tipped fans offer induced draft air for both clean and dirty air applications.
Our centrifugal radial tipped fans move corrosive and saturated air. The fan airstream can be constructed from stainless steel or other alloys for performance and aesthetics. Epoxy coatings and special linings are also available for durability, protecting the fan from corrosion and making the materials more resistant to chemicals, heat particulate and other elements. Both designs feature a non-overloading horsepower characteristic.

• Volume: up to 250,000 cfm
• Pressure: up to 60”wg
• Temperature: up to 1000°F
• Static Efficiency: up to 78%
• Drive: Belt & Direct

Centrifugal Fan Arrangements

There are two main categories of fan arrangements: Belt-Drive and Direct-Drive. There are multiple belt drive and direct-drive options available. Selection will depend on your application and preference.

Belt-Drive

The motor shaft drives the fan shaft through sheaves/pulleys and v-belts. Belt-driven fans provide speed and flexibility because they enable the fan operating speed to differ from the motor synchronous speed. There is power transmission loss associated with belt-driven fans that should be considered when selecting the motor horsepower.

Direct-Drive

The fan operates at the synchronous speed of the motor, as the motor drives the fan directly, either with the fan wheel mounted on the motor shaft or with the fan shaft directly coupled to the motor shaft. Direct-driven fans experience negligible power transmission losses.
