Technical Description
The fan uses a PA+GF impeller with 7 backward-curved blades and rotates clockwise when viewed toward the rotor. Air enters from all around the inlet. Ball bearings, IP55 protection, Class B insulation and S1 continuous duty support reliable operation from -25°C to +60°C.
Integrated safeguards include locked-rotor, thermal, over/undervoltage and overcurrent protection, plus soft start. The 500 ±20 mm cable and CCC, CE and RoHS compliance simplify installation.
