CNF（D）-1~30 marine electric heating fan

The marine electric heating fan is an air heating equipment taking advantage of electric heating tube and air circulation, the working principle is to continuously blow air to heat exchanger when self-contained axial fan is running, make cold air contact with high temperature winding and radiating tube, get heat, the heated air is discharged from louver, thus the fan will absorb cold air from motor end, and the heated air will exhaust from heating fan continuously, room temperature will rise constantly, and achieve the purpose of warming.
