Ventilator with flameproof and intrinsically safe double power do

Ventilator with flameproof and intrinsically safe double power double frequency governor BPJ-(75~160)/1140SF

BPJ-SF series ventilator with flameproof and intrinsically safe double power and double frequency conversion governor (hereinafter referred to as inverter) is a kind of variable frequency speed regulation equipment with double power and double control system developed for the main and standby two local ventilators in coal mine. The inverter is suitable for the underground coal mine with coal dust, gas and other explosive gas dangerous environment, automatic control of local fan, its unique dual power supply and double frequency conversion system and automatic speed regulation of wind speed according to the gas concentration of the working face, providing a solution for the normal ventilation of underground coal mine fan and hidden dangers in the gas discharge process.
