Product Description
Stall Crossflow Fan Uses and Working Principle:
This product is the latest type of research and invention of our company, gear cross-flow fan through the 5-step adjustment switch, change the frequency of the motor power supply to achieve speed regulation, adjust the range of size, reduce the speed of the motor in order to save electrical energy by 50%. off = off, 1-step from 500 rpm ~ 700 rpm, 2-step from 700 rpm - 900 rpm, 3-step from 900 rpm ~ 1,100 rpm, 4-step from 1,100 rpm ~ 1,300 rpm. The gears can be adjusted manually according to the ambient temperature change. According to the ambient temperature changes manually adjust the gear to adjust the size of the fan air volume, to solve the noise and air volume in the elevator car box, the implementation of ventilation and fresh air role, the product is unique at home and abroad independent invention of the research of new low-noise products.
