Centrifugal Forward Curved Fans for Industrial Applications
High-temperature process airstreams require specially designed centrifugal fans that are engineered for sustained heat, reliable performance, and long service life. Forward curved fans are a proven solution for moving large volumes of air at low static pressures in industrial furnaces, ovens, and other heat processing equipment.
Industrial Forward Curved Fan & Blower Overview
Also known as squirrel cage fans and blowers
The forward curved wheel features many short blades that curve in the direction of rotation. This impeller design is commonly used when you need high volume airflow in a compact footprint, often supplied in a plug configuration that mounts directly to an enclosure.
The AirPro forward-curved fan works in a wide range of industrial furnaces, industrial ovens, boilers, burners, and other heat-processing equipment. Generally designed to move high volumes of air at low static pressures, wheel design and materials of construction can be tailored to your operating temperature and process environment.
A forward-curved fan typically requires no ductwork, as the wheel is directly inserted into the enclosure. The motor, bearings, and drive components are positioned outside of the airstream to reduce heat exposure and simplify inspection and maintenance access.

FEATURED FAN
Custom Forward Curved Plug Fan for Industrial Oven Exhaust
AirPro designed a custom forward curved plug fan for a high-temperature industrial oven exhaust application. Forward curved fans are ideal for moving large volumes of air at low static pressures, making them well-suited for process heating and oven exhaust systems.
This unit was engineered as a free-standing Arrangement 1PL plug fan on a unitary base and mounted directly to the oven enclosure. Key design features include an insulated 12-inch plug, belt drive, and heat slinger to protect bearings and drive components in continuous high-temperature operation.
- Product Type: FCHS (forward curved)
- Description: Size 5; Arrangement 1PL (belt drive plug style with unitary base); max design temperature 800ºF
- Performance: 105,000 ACFM @ 12” wg static pressure
- Features: Forward curved wheel design; high-volume, low-pressure airflow capability; insulated plug construction; belt drive; unitary base; heat slinger for shaft cooling; free-standing Arrangement 1PL configuration; engineered for industrial oven exhaust and process heating applications.
How the Forward Curved Fan Works
Forward curved fans use a centrifugal design with many small, closely spaced blades that curve in the direction of rotation. As the wheel spins, air is drawn into the center of the fan and picked up by the forward curved blades, which push it outward into the housing and then into the airstream. This design is well suited for moving high volumes of air at low static pressures.
Because they deliver consistent airflow in compact systems, forward curved fans are often used in applications like furnaces, ovens, and other convection heating equipment where even air circulation and uniform temperature are important.
Applications
Common Industrial Forward Curved Fan Applications
High Temperature
Forward-curved fans handle high-temperature airflows with ease, offering reliable, high-volume performance in compact, plug-style configurations. Ideal for circulating air in enclosed, high-heat environments.
Process Heating
Forward-curved fans provide high airflow at low pressure, making them ideal for circulating heated air in ovens, dryers, and heat chambers. Their compact, quiet design ensures efficient, uniform heat transfer.
Additional Applications
Forward-curved centrifugal fans are well-suited for many other applications, including ventilation, air circulation, and equipment cooling in OEM systems and HVAC applications. Their compact design and quiet, high-volume airflow make them ideal for clean-air processes where space and efficiency are key.
