Technical Specifications:
The document provides detailed technical data for WOK-N series axial fans, designed for general ventilation purposes. Key specifications include supply voltage (230V), synchronous rotations per minute, motor power (ranging from 68W to 250W), admissible work temperature (+60°C), acoustic pressure levels at 1m and 5m distances, ingress protection (IP54), and weight (ranging from 2.65kg to 12.60kg).

Flow Charts:
The flow charts illustrate the static pressure against volume flow for different models (WOK-200-N to WOK-450-N), indicating performance characteristics across various operational conditions.

Purpose:
WOK-N fans are intended for ventilation in process halls, workshops, shops, storehouses, and livestock buildings. They are installed in wall openings or windows for air supply applications.

Structure:
The fans feature a cylindrical profiled housing with a shielding structure of concentric wire rings fixed at the outlet side. The motor with impeller is attached to this structure. The housing inlet is protected by a stamped net, ensuring safety and allowing installation both inside and outside rooms. The fans can operate in vertical and horizontal positions.

Shutters:
Shutters are available for each fan model, with dimensions specified for each type. They should be installed on the external wall, remaining closed at rest and opening in the direction of airflow when the fan starts.

Additional Equipment:
The document mentions the installation of shutters as additional equipment, emphasizing their role in controlling airflow direction and ensuring efficient operation.
