Double rotary vane vacuum pumps, Pumping speed 2L/min
Special PV hose for gas (clean stainless-steel tube can be used according to the demand of gas)
The system is specially made to prevent the danger of closure of the exhaust port, the blockage of the exhaust port and the excessive pressure of the furnace tube. The signal is obtained by the electric contact pressure meter or pressure sensor then the drive control module will close the electromagnetic inlet valve and starts the electromagnetic exhaust valve and the alarm. to ensure the furnace can be used properly and safely.
Base on gas atmosphere, to prevent the gas leak；Gas leakage alarm detected (indoor) air toxic, dangerous and other gas content exceeds a certain value, then the drive control module will shut-down the furnace, closes the inlet valve and open the air exhaust, to get the better and safer working environment.
