Overview: The document provides technical specifications and performance data for the FE2owlet fan series, measured according to ISO 5801 standards. It includes detailed information on various models, their design, airflow direction, weight, and electrical connections.

Specifications: The document lists multiple models of the FE2owlet fan, each with a unique article number, design type, airflow direction, and weight. The fans are designed with composite material impellers and have specific electrical connection requirements, including a connection cable of 55 cm length.

Performance Data: The performance data is provided for different voltage and frequency configurations (3~ 400V ±10% ∆/Y 50Hz and 1~ 230V ±10% 50Hz). Key parameters include power consumption (kW), current (A), speed (min-1), and efficiency (%). Graphs illustrate the relationship between airflow (qV in m³/h) and pressure (p in Pa), as well as sound levels (L in dB).

Design and Dimensions: The document details the dimensions for each model, including measurements such as B1, B2, B3, D1, D2, and others, which are crucial for installation and compatibility. The design types are categorized as A, D, L, I, H, K, and Q, each with specific dimensional attributes.

Key Observations: - The fans are measured in a full bell mouth without a guard grille. - The characteristic data follows the equation pd2 = 2.9·10-6·qV². - The document includes connection diagrams and dimension sheets for precise installation guidance.
