Description

Built for demanding industrial environments, the VN-Ring ATEX Axial Ring Fan offers customizable configurations to match specific ventilation needs. It is available in diameters ranging from 310 mm to 1,250 mm and operates with an ATEX-certified IP55 motor, supporting both 230V single-phase and 400V three-phase power. The fan delivers a maximum airflow of 80,000 m³/hr with a pressure capacity of up to 750 Pa, ensuring efficient air movement in hazardous areas.

Its casing is available in steel, aluminum, or stainless steel, while impellers can be made of plastic or aluminum, with adjustable angles for optimized performance. Designed for flexibility, the fan supports both motor-to-impeller and impeller-to-motor airflow configurations and can be controlled via a frequency converter for precise speed regulation. Additional options include motors with various voltage and certification levels, as well as accessories such as protection grids, silencers, shutters, switches, and terminal boxes.
