The D-RG148H EC gas blower is designed for controlled combustion-air delivery in gas boilers, heating equipment, and industrial burner systems.
Manufactured by Ningbo E-POWER Energy Saving Technology Co., Ltd., this blower combines electronically commutated motor technology with a centrifugal design to support adjustable airflow and OEM equipment integration.
D-RG148H Technical Specifications
The D-RG148H EC gas blower provides the following published technical specifications:
| Parameter | Specification |
|---|---|
| Model | D-RG148H |
| Rated Voltage | 100–120 / 220–230 VAC |
| Frequency | 50/60 Hz |
| Power Input | 300W ±10% |
| Catalog Combustion Power | 130 kW |
| Maximum Speed | 7,300 RPM ±10% |
| Airflow | 260 m³/h |
| Maximum Static Pressure | 4,100 Pa ±5% |
| Net Weight | 2.1 kg |
Maximum airflow and static pressure represent different operating points. Actual performance depends on system resistance.
These specifications provide a starting point for OEM engineers evaluating combustion-air requirements and electrical compatibility.
Key Features and Airflow Performance
The D-RG148H EC gas blower uses EC motor technology to support electronically controlled airflow.
Its centrifugal impeller and housing are designed to deliver air against system resistance in heating and combustion equipment.
Key features include adjustable motor speed, compact construction, and application-specific airflow performance.
The published airflow-pressure curve also allows engineers to compare D-RG148H with D-RG148 and D-RG148L.
Complete performance-curve verification is necessary before selecting a blower for a specific system.
PWM Speed Control and Installation
The D-RG148H supports PWM speed regulation for compatible electronic control systems.
According to the supplied wiring documentation, startup requires a PWM duty cycle above 5%. Full-speed operation is specified at 100% duty cycle or without a PWM connection.
The blower has approximate overall dimensions of 184.4 × 190.7 × 145.2 mm.
Installation guidance specifies a horizontal shaft or motor-mounted-on-top arrangement.
OEM engineers should verify connector assignments, electrical requirements, mounting dimensions, and installation conditions before integration.
Applications of D-RG148H EC Gas Blower
The D-RG148H EC gas blower can be evaluated for several heating and combustion applications.
Gas Boilers: Combustion-air supply for compatible residential and commercial boiler systems.
Industrial Heating: Airflow support for heating equipment requiring controlled air delivery.
Gas Burner Systems: Integration with suitable burner controls, gas valves, and mixing components.
Actual compatibility depends on the complete combustion system and must be verified through appropriate testing.
