Blauberg Primo 355

Inline fans for supply and exhaust ventilation of various commercial and industrial premises requiring powerful air flow. The fans are compatible with Ø 150, 200, 250, 355 and 400 mm air ducts. Combines wide capabilities and high performance features of axial and centrifugal fans, providing powerful air flow.

The casing is made of polymer (for models 355 and 400 the casing is additionally reinforced with a metal housing). Due to the conically shaped polymer impeller with specially profiled blades, the air stream circular velocity increases, which results in higher air flow and pressure, as compared to characteristics of standard axial fans. The specially designed diffuser, impeller and airflow rectifier at the fan outlet provide smooth air flow distribution and enable the best combination of high capacity, powerful pressure and low noise. The fan casing is equipped with an airtight terminal box for connection to power mains.

Primo 150, 200, 250		Primo 355, 400

Three-speed high-efficient asynchronous motor. 220–240 V single phase at 50 (60) Hz. Equipped with ball bearings for longer service life (up to 40 000 hours). All motors have thermal overload protection.

The fans are controlled by either a three-stage CDPE-3 E5 controller or a smooth thyristor controller connected to the maximum speed terminal.

The fans can be mounted at any place and at any angle within the ductwork system. Several fans may be installed in one system in parallel to attain higher air capacity or in series to increase operating pressure in the system. The fan casing is equipped with fixing brackets for suspended mounting. The fans can be installed using the appropriately sized UM Primo bracket (ordered separately, available for models 355 and 400).
