The heating fan is a combined unit composed of a fan, a motor and a radiator. It is suitable for various types of workshops where the air is allowed to recirculate. When the air does not contain dust and flammable gases, it can be used for circulating air heating.

The heating fan is mainly composed of an air heater and a fan. The air heater dissipates heat, and then the fan is sent out to adjust the indoor air temperature. Air heaters consist of spiral finned tubes. For example, the heat dissipation pipe of the steam heater is wound on a seamless boiler tube with a wall thickness of Φ21.5 with special equipment of aluminum strip, and the sheet distance is 2.5mm. The exhaust pipe and the heat medium circulation pipe are integrally welded. The working pressure is below 0.8MPa.
