Feature:1. 30S Fast Heating: After electrifying, PTC quickly converts electric energy into heat energy, and hot air can be felt within 30 seconds, so it heats quickly.2. Constant Temperature Heating: Insulated fan heater uses ceramic constant temperature heating technology to continuously output heat and automatically work at constant temperature.3. Reinforced Nylon Shell: PTC heating fan uses PA66 reinforced nylon shell, which has high temperature resistance, insulation and good safety protection.4. Long Service Life: PTC heating fan can provide heat source for 10,000 hours continuously, and repeated switching will not affect the service life, so it is durable.5. Compact Design: The heater is designed in a compact structure, the volume of which is about the same as that of a mouse, and it can be placed in a narrow space without occupying too much space.Specification:Item Type: PTC Air HeaterMaterial: Reinforced Nylon ShellHeating Material: PTC Ceramic Heating PieceMaterial: High Temperature Resistant WireWire Length:Approx. 20cm / 7.9inProduct Size:Approx. 60 x 60 x 42mm / 2.4 x 2.4 x 1.7inTemperature Error: 10Operating Voltage of Heater:DC 24VOperating Voltage of Fan: DC 24VPower: 80W25%.Package List:1 x PTC Air HeaterNote:Please supply the power according to the voltage used.
