Rotron AXIMAX 1 Small Vaneaxial Fans

Transcription

1 Rotron AXIMAX Small Vaneaxial Fans General Small Vaneaxial Information Small Vaneaxial Fans are compact, high-speed fans whose airflow is parallel to the motor shaft. The impeller and guide waves are of airfoil construction for maximum aerodynamic efficiency and minimum acoustical noise. These fans are designed for use in tightly packaged airborne black boxes where sizes and weight must be held to an absolute minimum, where reliability is critical, and where high heat loads must be dissipated with cooling air. Small Vaneaxial Fans come in a variety of voltages and frequencies and are available with lead wires, terminal blocks and MS connectors. Most units are available with an optional internal Fan Performance Sensor (FPS) or an external Low Speed Warning Device (LSWD). Some units are available with an internal Low Speed Warning Device (LSWD). Rotron AXIMAX Aximax Series: Maximum Performance Curve*. Static Pressure (inches water gauge). RPM.
