EC133 Single-Inlet EC Centrifugal Blower
EC133 (part no. DGF2E133A1) combines a galvanized steel sheet impeller with a brushless DC external rotor motor. Its compact single-inlet format supports OEM equipment layouts where airflow, pressure and installation space must be considered together.
The 0-10 VDC/PWM control input allows system-level airflow adjustment. Select the operating point from the supplied airflow-pressure curve, and confirm electrical connections, enclosure conditions and mounting clearances before integration.

Application and Integration
Potential uses include ventilation, air handling, heating and equipment cooling where the cataloged performance meets the complete system requirements. For combustion equipment, suitability must be confirmed by the OEM through system-level testing; the blower alone does not determine the gas-air ratio.
OEM inquiries can include the target duty point, supply voltage, control signal, mounting orientation and required approval conditions.
