Centrifugal blowers provide airflow for industrial ventilation, HVAC, filtration, and equipment cooling applications. Their design allows air to move through systems containing ducts, filters, and other airflow restrictions.
Ningbo E-POWER Energy Saving Technology Co., Ltd. offers centrifugal blowers for OEM equipment manufacturers, combining motor engineering, electronic control technology, and manufacturing capabilities.
What Are Centrifugal Blowers?
A centrifugal blower draws air into a rotating impeller and directs it outward, generating airflow and pressure.
Unlike axial fans, centrifugal blowers are commonly used where equipment must overcome resistance from filters, ducts, and ventilation channels.
EC centrifugal blowers use electronically commutated motors to support adjustable-speed operation with compatible control systems.
Actual performance depends on the fan design, operating speed, installation conditions, and system resistance.
Main Types of E-POWER Centrifugal Blowers
E-POWER provides different centrifugal blower configurations for industrial applications.
| Product Type | Main Characteristics | Typical Applications |
|---|---|---|
| EC Forward-Curved Fans | Compact designs with forward-curved impellers | Ventilation and air-handling equipment |
| EC Backward-Curved Fans | Backward-curved impellers with different airflow-pressure characteristics | HVAC, filtration, and industrial ventilation |
Forward-curved fans can be considered for compact equipment layouts, while backward-curved designs are often evaluated for systems requiring substantial static pressure.
The appropriate choice depends on the equipment's operating requirements.
E-POWER Centrifugal Blower Models
E-POWER offers multiple EC centrifugal fan sizes and performance configurations.
| Product Model | Airflow | Air Pressure | Power |
|---|---|---|---|
| EC Ø133-H55 | 260 m³/h | 320 Pa | 62W |
| EC Ø175 | 810 m³/h | 744 Pa | 105W |
| EC Ø225 | 1,110 m³/h | 425 Pa | 85W |
| EC Ø355 | 3,500 m³/h | 805 Pa | 390W |
Published maximum airflow and pressure values do not necessarily occur simultaneously. Actual performance requires verification using fan performance curves.
These models provide different options for OEM ventilation and industrial airflow systems.
Common Applications of Centrifugal Blowers
Centrifugal blowers can be considered for several equipment categories:
-
HVAC Equipment: Air circulation and ventilation systems.
-
Industrial Air Filtration: Airflow through filters and purification equipment.
-
Equipment Cooling: Air movement for machinery and electrical equipment.
-
Industrial Ventilation: Air delivery in compatible ducted systems.
Application suitability depends on airflow requirements, pressure resistance, operating conditions, and equipment design.
How to Select the Right Centrifugal Blower
OEM engineers should evaluate airflow, static pressure, electrical compatibility, speed-control requirements, and installation dimensions.
The selected blower must meet the actual operating point rather than simply having the highest catalog airflow.
Testing within the completed equipment helps verify airflow performance, noise, temperature, and installation compatibility.
