Performance Characteristics
The performance of each fan model is depicted through characteristic diagrams showing the relationship between pressure (Pa) and volume flow rate (m³/h). These diagrams help in understanding the operational efficiency and capacity of the fans under different conditions.

Electrical Specifications
The fans operate on a three-phase power supply of 380...480 V at 50/60 Hz with an IP54 protection rating. The power input (P1), current (I), rotational speed (n), and temperature resistance (tR) are specified for each model, indicating their electrical and thermal performance.

Design and Dimensions
The document includes detailed dimension sheets for each fan model, specifying measurements such as diameter, length, and various other critical dimensions. This information is crucial for installation and integration into different systems.

Weight and Construction
Each fan model is listed with its weight and construction type, which are important for handling and installation. The document also provides article numbers for easy reference and ordering.

Noise Levels
Noise levels (dB) are provided for each fan model, indicating the sound pressure levels during operation. This is essential for applications where noise control is a priority.

Connection Diagrams
Connection diagrams are included for each model, providing guidance on electrical connections and ensuring proper installation and operation.
