Radial Bladed Fans
Heavy Duty, High Pressure Industrial Workhorse
Radial bladed centrifugal fans are the most robust and durable fan design available for high-pressure, heavily contaminated, and demanding industrial air and gas handling applications.
Often referred to as the industry’s "workhorse", radial bladed fans feature straight, rugged blades designed to withstand abrasion, material buildup, moisture, and extreme operating conditions.
Industrial Fan Systems (IFS) radial bladed centrifugal fans are engineered for reliability in dirty, abrasive, wet, and particulate-laden environments. With proven performance in mining, pneumatic conveying, combustion air, and process industries, the IFS-RB range delivers the high-pressure capability and mechanical strength required where other fan types are unsuitable.
Radial Bladed Centrifugal Fans – The Industry Workhorse for High Pressure Applications
What Is a Radial Bladed Centrifugal Fan?
A radial bladed centrifugal fan uses straight blades that extend radially from the hub. Unlike backward curved or airfoil designs, radial blades prioritise structural strength and pressure generation over aerodynamic efficiency. This geometry enables the fan to handle high system resistance, material loading, and rapidly fluctuating operating conditions.
Radial bladed fans are commonly selected for applications involving heavy dust, wet air, scrap, or abrasive particles, where blade fouling or erosion would compromise more efficient fan types.
Why Choose a Radial Bladed Fan?
Advantages
High Pressure Capability: Delivers strong static pressure for high-resistance systems.
Exceptional Structural Strength: Straight blades resist deflection and erosion.
Packing Resistant Design: Maintains performance in dusty and wet environments.
Steep Performance Curve: Rapid pressure response under fluctuating loads.
Extreme Application Tolerance: Performs reliably where other fan types fail.
Radial bladed centrifugal fans are selected when reliability, pressure capability, and durability are more critical than peak efficiency.
Key Features & Benefits
Radial Bladed Impeller Design: The robust, straight blade design provides maximum mechanical strength and a non-clogging airflow path, making radial bladed fans ideal for particulate-laden and abrasive air streams.
Steep Performance Curve: Radial bladed fans deliver an immediate pressure “punch,” making them well suited to pneumatic conveying, material handling, and combustion systems with variable resistance.
Packing & Fouling Resistance: Engineered to resist vibration and imbalance caused by material buildup, ensuring stable operation in dirty and wet environments.
Heavy-Duty Industrial Construction: Manufactured from carbon steel, stainless steel, or alloy materials with optional surface protection coatings for corrosive or high-temperature environments.
Flexible Drive & Mounting Options: Available in direct drive or belt drive configurations, with horizontal or vertical mounting options to suit site constraints and maintenance requirements.

SWSI & DWDI Configurations
The Airfoil Fan is available in two configurations to suit different airflow and pressure needs.
SWSI (Single Width Single Inlet)
Best suited for moderate
airflow requirements,
compact installations, and
higher pressure applications
where space is limited.
DWDI (Double Width Double Inlet)
Designed for high airflow
applications, typically used in
large HVAC systems, process
ventilation, and central
plant installations.
