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.
