Commercial extractor fans , here's a description of each type of fan and there use,
Box Fans
90 deg - motor out of air-stream - For high heat and high pressure and dirty applications
Axial - motor in air-stream - For high pressure and dirty applications
Axial Fans
Plate axial - for wall mounting ow pressure
Cased axial - for mounting with spiral ducting low pressure
Turbo Fans Contra-rotating - for high pressure applications or constricted ductwork
Mixed flow Fans - high airflow medium pressure for clean applications
EASY FAN SELECTOR
Fan Type | Description | Applications |
---|---|---|
Backward Curved Box Fan (Motor Out of Air-stream) | Fan blades curve backward, motor located outside the airflow. | Ideal for handling clean air, suitable for applications where the motor needs protection from the air-stream. Commonly used in high temperature, high throughput commercial kitchens |
Backward Curved Box Fan (Motor in Air-stream) | Fan blades curve backward, motor located within the airflow. | Suitable for medium-temperature and contaminated air applications where motor cooling by the air-stream is beneficial. Used in high throughput and medium heat commercial kitchens |
Axial Fan | Moves air along the axis of the fan, similar to a propeller. | Best for low-pressure, high-volume airflow applications. Common in ventilation, cooling, and exhaust systems and fresh air replacement systems. |
Turboprop Fan | Combines elements of axial and centrifugal fans. | Suitable for applications needing a balance of high pressure and high volume. Used in cooling and drying processes. |
Mixed Flow Fan | Combines characteristics of axial and centrifugal fans, providing a mixed flow of air. | Ideal for medium pressure and medium volume applications. Used in ducted HVAC systems and where compact design is required. |
