SUBSTITUTE GENERIC D1G133-AB39-22 Centrifugal Blower

The EBMPAPST D1G133-AB39-22 is a 48 VDC centrifugal blower built for inverter cooling, featuring a 133 mm impeller and a rated 105 W input that spins at approximately 1,780 RPM to deliver airflow through power-electronics enclosures. Its galvanized sheet-steel housing uses a dual-inlet design and a ball-bearing drive, and the unit weighs about 3.3 kg, giving it durability and stability in demanding environments. It is specified for a nominal 48 VDC supply with a voltage range of 36–57 VDC, making it compatible with VACON inverter cooling duties and other DC power-electronics cooling applications. The model is cataloged as a “no mounting” variant, shipping without integrated mounting feet or brackets, so system integrators must provide appropriate mounting provisions for installation. With a 133 mm blade diameter and a motor speed of 1,780 RPM, this blower provides a solid balance of airflow and electrical efficiency for compact inverter modules, drive electronics, and other cooling needs in industrial setups. This combination of robust construction and precise electrical ratings makes the D1G133-AB39-22 a common choice for reliable, inverter-focused airflow in confined spaces.
