VEVKF4E550

The VEVKF Series Axial Duct Fans provide high airflow performance in a robust steel casing. Designed for low-pressure ventilation systems, these in-duct fans deliver large air volumes with reliable, continuous operation.

Application

Suitable for combined supply and exhaust ventilation systems in a wide range of commercial, industrial, and utility premises. Ideal where high air capacity is required at relatively low system resistance, including warehouses, workshops, and plant rooms.

Features / Benefits

• Low-pressure axial fan for high-capacity ventilation systems
• Steel casing and impeller with protective polymer coating for durability
• Two- or four-pole, single- or three-phase asynchronous motor with external rotor (model dependent)
• Built-in thermal overheating protection and ball bearings rated for at least 40 000 hours of service life
• IP44 motor protection rating for reliable operation in demanding environments
• Smooth or step speed control using thyristor or autotransformer controllers
• Multiple fans can be connected to a single controller within rated load limits
• In-duct mounting via connecting flanges
• External terminal box on the fan casing for straightforward electrical connection
