Blauberg Ventilatoren GMBH

Blauberg Ventilatoren GMBH is based in China and lists 16 active products in its catalogue. The company’s offerings fall under the Electric Fans & Blowers, Agriculture, Fan Impellers/Regulators and Electric Ceiling Fans categories. Its product list includes AC and EC centrifugal fans with forward and backward curved impellers, AC and EC axial fans of various diameters, and related blower and motor components. The catalogue references HS chapter 84, with one item explicitly coded under HS 8414.59 for a backward‑curved centrifugal fan with a galvanized steel impeller.

The centrifugal fan range covers diameters from 120 mm to 355 mm, including backward‑curved models at 175 mm, 180 mm, 225 mm and 250 mm, and forward‑curved versions at 120 mm and 355 mm. Axial fans are described as stamped or welded blades with diameters of 200 mm, 300 mm, 400 mm and a 5‑blade configuration. Additional items include a helix‑type blower, an external‑rotor AC motor (92 mm), and various fan impeller configurations. All products are described using standard fan terminology such as AC (alternating current) and EC (electronically commutated) motor technology.

The catalogue lists AC centrifugal fans (forward and backward curved), EC centrifugal fans (forward and backward curved), AC axial fans (stamped and welded), EC axial fans, a helix‑type blower, and an external‑rotor AC motor. In the fan industry, centrifugal fans are typically classified by impeller curvature, with backward‑curved designs offering higher pressure and efficiency, while forward‑curved versions are common for low‑pressure, high‑flow applications. Axial fans are graded by blade material (steel, aluminum or reinforced plastic) and blade count, influencing airflow rates that usually range from 500 CFM for small 120 mm fans up to 5,000 CFM for larger 400 mm units. EC (electronically commutated) models are expected to meet IEC 61800‑5‑1 efficiency classes, often IE2 or IE3, and to provide variable speed control via built-in inverters. Materials such as galvanized steel, aluminum alloy and polymer‑coated blades are standard, with galvanized steel impellers, as noted for the 225 mm centrifugal fan, offering corrosion resistance for agricultural and industrial environments.
