Centrifugal Fans: The Ultimate Guide for Industrial Airflow Solutions
For over 20 years, WuJiang DeshengXin Purification Equipment Co., Ltd has engineered high-performance centrifugal fans for industries worldwide. From cleanrooms to heavy-duty factories, these fans are critical for ventilation, cooling, and contamination control. This guide explores how centrifugal fans work, their key applications, selection criteria, and why partnering with an expert manufacturer ensures long-term reliability.
What is a Centrifugal Fan?
A centrifugal fan (or centrifugal blower) uses rotating impellers to accelerate air radially outward, creating high-pressure airflow. Unlike axial fans, they excel in systems requiring strong static pressure to overcome resistance in ducts, filters, or equipment.
Key Advantages:
High efficiency in confined spaces
Durability for harsh environments (dust, moisture, chemicals)
Low noise at optimized RPM
Customizable blade designs (forward-curved, backward-curved, radial)

Top Industrial Applications of Centrifugal Fans
1. HVAC Systems
Centrifugal fans maintain air circulation in large facilities like warehouses, hospitals, and shopping malls. They balance temperature and filter airborne particles.
2. Cleanrooms & FFU (Fan Filter Units)
Precision fans ensure laminar airflow in electronics, semiconductor, and pharmaceutical cleanrooms. Custom designs minimize vibration and particulate contamination.
3. Industrial Exhaust & Fume Extraction
Explosion-proof centrifugal fans safely remove hazardous fumes in chemical plants, welding facilities, and paint booths.
4. Grain Storage & Agricultural Ventilation
Corrosion-resistant fans regulate humidity and temperature in silos, preventing mold and spoilage.
5. Air Shower Systems
High-velocity fans strip contaminants from personnel or goods entering controlled environments.
Critical Factors When Choosing a Centrifugal Fan
1. Performance Requirements
Airflow (CFM/m³/h) and static pressure (Pa)
Operating temperature and environmental conditions (e.g., corrosive gases)
Noise restrictions (dB levels)
2. Blade Design
Forward-curved blades: Lower noise, ideal for HVAC.
Backward-curved blades: High efficiency, suited for heavy-duty systems.
Radial blades: Durable for abrasive or high-pressure applications.
3. Material & Construction
Stainless steel, aluminum, or polymer housings
Anti-corrosion coatings for humid/dusty environments
4. Energy Efficiency
5. Certifications & Compliance
