Key Benefits of Centrifugal Blower
Selecting a STATFIELD blower means investing in more than just a fan; it’s an investment in long-term operational stability and efficiency. Here’s what sets our industrial air blowers apart:
- Superior Energy Efficiency: Our backward-curved and inclined impeller designs are engineered for maximum aerodynamic efficiency, significantly reducing horsepower requirements and lowering your long-term energy costs.
- Robust Construction & Durability: Built with high-grade materials, every centrifugal blower is designed for a long service life, even in corrosive or high-temperature environments, minimizing maintenance needs and replacement frequency.
- Precise Performance & Stability: We provide stable performance across the entire operating range, preventing system surging and ensuring consistent airflow and pressure for your critical processes.
- Operational Flexibility: With multiple drive arrangements (Direct, Belt, Coupling) and a wide performance range, our systems can be tailored to fit your specific spatial and performance constraints.

Frequently Asked Questions
What is a Centrifugal Blowers and how does it work?
A centrifugal blower fan is a type of air movement device that uses a rotating impeller to increase the pressure and flow of air. Unlike axial fans that pull air straight through, a centrifugal fan draws air in axially through the center (the eye of the impeller) and then blows it out radially at a 90-degree angle, thanks to centrifugal force. This design allows it to generate higher pressure, making it ideal for systems with resistance, like ductwork or filters.
What are the main advantages of a blower over an axial fan?
Higher Pressure Capability: Excels in applications where air must be pushed through resistance.
Superior Efficiency in Static Systems: More energy-efficient for ducted or restricted airflow paths.
Stable Performance: Less prone to performance drops under back-pressure.
Quieter Operation: Generally operates at a lower noise level than comparable axial fans.
Handling Dirty/Dusty Air: Many designs are well-suited for harsh environments with particulates.
Where are centrifugal air blowers & fan commonly used?
They are versatile and used across numerous industries:
HVAC Systems: For building ventilation, air conditioning, and heating.
Industrial Processes: Drying, cooling, fume extraction, and material handling (pneumatic conveying).
Air Pollution Control: As the driving force for dust collection systems.
Equipment Cooling: Cooling electrical panels, engines, and machinery.
Medical Devices: In equipment like laser machines and analyzers.
What are the different types of centrifugal fan impellers and how do I choose?
The impeller design dictates performance. The main types are:
Forward Curved (FC / Squirrel Cage): Many short blades curved in the direction of rotation. Best for high-volume, low-pressure applications (e.g., residential furnaces, air handling units). Compact and cost-effective but less efficient.
Backward Curved (BC): Blades that curve against the direction of rotation. Best for high-efficiency, medium-to-high pressure applications. They have a non-overloading power characteristic, making them ideal for industrial HVAC and clean air systems.
Backward Inclined (BI): Flat blades inclined against the direction of rotation. A robust option for handling dirty air and moderate pressures, often used in dust collection and material handling. They are also non-overloading.
What do "Non-Overloading" and "Self-Limiting" mean?
This is a key advantage of Backward Curved and Backward Inclined fans. It means that the horsepower required by the fan motor peaks and then decreases as the flow increases beyond its best efficiency point. This prevents the motor from being overloaded, even if the system resistance drops to zero (e.g., if a duct falls off), protecting your motor from burnout.
What information do I need to provide to select the right blower?
To ensure a perfect match, provide:
Required Airflow: in CFM (Cubic Feet per Minute) or m³/hr.
Static Pressure: The resistance the fan must overcome (from ducts, filters, grilles, etc.).
Air Density / Conditions: Temperature, altitude, and any contaminants.
Application: What are you moving air for? (e.g., exhaust, cooling, conveying).
Power Supply: Voltage, Phase, Frequency (e.g., 230V, 1-Phase, 50Hz).
Mounting & Connection: How will it be installed? (e.g., base-mounted, ducted inlet/outlet).
What is the difference between a blower and a fan?
While the terms are often used interchangeably, a key difference is the pressure they generate.
- Fans: Typically generate lower pressure (up to ~0.5 psi) and move large volumes of air.
- Blowers: Operate at higher pressures (0.5 to 2.0 psi) and are designed to overcome significant system resistance.
- Centrifugal “blowers” are essentially high-pressure centrifugal “fans.”
What are common maintenance requirements?
Regular Inspection: Check for dust buildup on the impeller and housing.
Lubrication: Schedule for bearings (if not permanently sealed).
Vibration Checks: Imbalance is a common failure point.
Belt Tension: For belt-driven models, check and adjust regularly.
Filter Maintenance: Clogged filters increase system pressure and fan load.
My blower is vibrating excessively! What could be the cause?
Common causes include:
- Imbalance: Dirt/debris buildup on the impeller or impeller damage.
- Bearing Failure: Worn-out bearings need replacement.
- Misalignment: For direct-drive fans, misalignment with the motor shaft.
- Resonance: The fan’s operating speed matches the natural frequency of the supporting structure.
Can I control the speed of a centrifugal air blower?
Yes, and it is highly recommended for energy savings. Speed is most efficiently controlled using a Variable Frequency Drive (VFD). Reducing the fan speed by just 20% can lower energy consumption by nearly 50%, according to affinity laws.
