The bags are made of NOMEX and can bear 220℃. The flexible clamps at the bag mouth perfectly match with bag supporters which is good for installation. The top cover is easy to open for inspection or replacing bags. Pulse type cleaning devices are installed on the collector, and auto-control panel with auto-pulse timer are installed in the control box. The solenoid valve is to control the cylinder and top door. The exhaust fan provides negative pressure and suction air to clean the bags orderly, and cleaning area is above 94%.

The dusts fall down and gather in the dust collector box and then will be discharged by the screw conveyor. To make sure the bag works safely and reliably, temperature control system and transfinite ceasefire device are mounted to ensure the smoke temperature is within the rated range (normally 220℃, short-time temperature resistant limit is 240℃). If it is higher, the control system will cut the fuel supply automatically. The temperature measuring system between exhaust fan and dust collector can show the burning condition as well and remind the operator when the temperature is blow 80℃.
