Product catalog summary

Overview: The document provides technical specifications and details for DMN centrifugal fans with forward-curved blades, designed for low-pressure applications. These fans are suitable for cooling machines, lamps, and motors, as well as for transporting clean or dusty air.

Specifications: The fans operate within a flow rate range of 50 to 2500 m3/h and a pressure range of 23 to 150 mm H2O. Standard models can handle air temperatures up to 80°C, while special models can withstand up to 250°C. Stainless steel versions and ATEX-compliant models are available upon request.

Construction: The fans feature casings made from pressed and spot-welded steel sheets, galvanized impellers with forward-curved blades, and are powered by 2 or 4-pole electric motors.

Performance Data: The document includes detailed performance charts for various models (DMN 202, DMN 252, DMN 302, etc.), showing relationships between flow rate (Qv), motor power, and pressure (both total and static). Noise levels in dB(A) are also provided for each model.

Orientation and Rotation: The fans can be oriented in various positions (e.g., RD 270) and can rotate clockwise or anti-clockwise, as viewed from the motor side.

Dimensions and Weight: Detailed dimensions and weights for each fan model are provided, indicating the size and installation requirements.

Key Considerations: The document emphasizes the importance of selecting the appropriate fan model based on specific application requirements, including temperature, pressure, and flow rate needs.
