Key Advantages of Our Industrial Centrifugal Blowers
Superior Static Pressure Performance: Our industrial centrifugal blower fan designs generate static pressures from 300Pa to 1315Pa, enabling effective air movement through long ductwork, dense filters, and high-resistance systems. This makes them ideal for applications where standard axial fans fail, answering the common question of centrifugal blower vs axial fan performance differences.
Advanced Motor Technology: Featuring brushless EC and DC motors with 50,000-hour L10 lifespan, our centrifugal blower motors deliver exceptional reliability and energy efficiency. Integrated protections including soft-start, thermal overload, locked-rotor detection, and reverse polarity safeguards ensure uninterrupted operation in critical applications.
Precision Control and Monitoring: All models support 0-10VDC/PWM speed control and FG tachometer output for seamless integration with building automation systems. This intelligent control capability allows real-time airflow adjustment based on environmental conditions, optimizing energy consumption while maintaining performance.
Durable Construction for Harsh Environments: Galvanized steel centrifugal blower impellers resist corrosion in humid and chemical-laden atmospheres. IP44 to IP54 protection ratings shield internal components from dust and moisture ingress. Operating temperature ranges from -25°C to +60°C accommodate both cold storage facilities and hot industrial environments.
Application Use Cases Across Industries
HVAC and Building Ventilation: Our air centrifugal blower solutions maintain consistent temperature regulation and air quality in commercial buildings, shopping centers, and airports. High static pressure capability overcomes resistance in long-duct systems and maintains airflow through multiple filtration stages.
Industrial Dust Collection and Extraction: Effectively remove wood dust, metal shavings, chemical particles, and fumes from manufacturing facilities. The backward curved centrifugal blower design prevents particle buildup on impeller blades while maintaining high efficiency across varying loads.
Process Cooling and Equipment Ventilation: Protect critical electronics, power supplies, and heavy machinery from thermal damage. Our small centrifugal blower models fit compact spaces while delivering focused cooling airflow to heat sinks and thermal management systems.
Cleanroom and Laboratory Applications: Maintain stringent air quality standards with precise airflow control. Low noise operation (58-76 dB(A)) makes these units suitable for noise-sensitive environments without compromising performance.
Food Storage and Refrigeration: Ensure efficient temperature regulation in commercial refrigerators and cold storage facilities. Our blowers operate reliably in sub-zero temperatures while maintaining consistent airflow for proper thermal distribution.
Selection Guide: Choosing the Right Centrifugal Blower
Selecting the appropriate industrial centrifugal blower requires careful consideration of several factors:
Airflow Requirements: Calculate required CFM or m³/h based on room volume, air changes per hour, and application needs. Our range spans from 300 m³/h for small spaces to 1220 m³/h for large industrial applications.
Static Pressure Needs: Measure system resistance including ductwork length, bends, filters, and outlet restrictions. Match blower static pressure capability to overcome total system resistance with appropriate safety margin. High pressure centrifugal blower models handle systems up to 1315Pa.
Voltage and Power Supply: Consider available electrical infrastructure. EC centrifugal blower models suit mains-powered installations, while DC options offer flexibility for battery backup, solar systems, and mobile applications. Our 12v centrifugal blower fan units provide solutions for automotive and portable equipment.
Environmental Conditions: Evaluate temperature extremes, humidity levels, dust concentration, and chemical exposure. Select appropriate IP rating and construction materials to ensure longevity. Waterproof models with IP44+ ratings suit outdoor and wash-down environments.
Control Requirements: Determine if variable speed control is necessary for energy optimization and application flexibility. All our models support PWM and 0-10V analog control for precise airflow modulation.

Frequently Asked Questions
What is the difference between a centrifugal blower and an axial fan?
A centrifugal blower uses a rotating impeller to accelerate air radially and convert velocity into static pressure through the scroll housing. This design excels at generating high pressure to overcome system resistance. An axial fan moves air parallel to the shaft, providing high airflow at lower pressures. For applications requiring ductwork, filtration, or distance air movement, centrifugal blowers significantly outperform axial fans. Understanding this fundamental difference helps in selecting the right air moving solution for your application.
How do I calculate the required static pressure for my system?
Static pressure requirements depend on total system resistance including duct length, bends, diameter changes, filters, and outlet restrictions. As a general guideline, straight ductwork requires approximately 0.1-0.2 Pa per meter, 90-degree bends add 10-20 Pa each, and HEPA filters may require 200-500 Pa. Sum all components and add 20-30% safety margin. Our engineering team can perform detailed pressure drop calculations for complex systems - explore our industry solutions for application-specific guidance.
Can these blowers operate in dusty or humid environments?
Yes, our industrial centrifugal blower models feature IP44 to IP54 ingress protection ratings, safeguarding internal electronics from dust and water spray. Galvanized steel impellers resist corrosion in humid conditions. For highly corrosive environments (chemical processing, coastal installations), we offer optional epoxy coating and stainless steel construction. Operating humidity range extends from 5% to 90% RH without condensation.
What types of speed control are supported?
All our centrifugal blower motors support dual control inputs: 0-10VDC analog voltage for continuous speed modulation and PWM (pulse width modulation) for digital control. This flexibility enables integration with PLCs, building automation systems, and simple potentiometer controls. Real-time FG tachometer output (3-5 pulses per revolution) provides closed-loop feedback for precise speed verification and system diagnostics.
How long do these blowers last in continuous operation?
Our brushless EC and DC motors achieve 50,000-hour L10 lifespan (90% survival rate) under standard conditions (40°C ambient, 15-65% RH). This translates to approximately 5.7 years of continuous 24/7 operation. In intermittent duty applications, service life extends significantly. Ball bearings rated to 80°C and robust electronics ensure reliability. We provide 24-month warranty on motors and 12-month warranty on other components with complimentary repair and replacement services.
