according to the price in January 22, the price of hot air blower is around 4 yuan.
use the hot air blower in a well-ventilated place, and before using the hot air blower, provide at least 2.8 square meters of ventilation openings for every 3kW (1, btu/hr).
use the hot air blower in the place where there is no flammable gas or high dust content, and it can only be used at the voltage and frequency specified on the nameplate. To keep the voltage stable, only use plugs with grounding.
Extended information:
The circulating hot air blower uses the patented cooling device, and the continuous intake air temperature can reach 23℃. The air volume is adjusted by frequency converter, which is more energy-saving, highly controllable and less heat loss.
the standard hot air blower adopts international brand electrical main controls (such as frequency converter, PID temperature controller, SSR, circuit breaker, intermediate relay, magnetic switch, etc.); The accuracy of PID temperature controller is .1%, and it is equipped with remote switch.
the economical hot air blower adopts international brand electrical main controls (such as PID temperature controller, SSR, circuit breaker, intermediate relay, magnetic switch, etc.), without frequency converter, but with motor protector; The accuracy of PID temperature controller is .1%.
