Hull of this machine is designed in line with flow type of whirlwind dust catcher: to separate dust with large size granule firstly, then remove fine dust with filtering bag. The revolved nozzle will burst back-blow current from top to lower place periodically to force the bag to expand, shake off dust on the filtering bag which enhances service life of filtering bag and assuring dust removing effect.
This machine combines advantages of machines from home and abroad with good airproofing performance, agile turning, filtering bag can be convenient to be changed, dust removing efficiency is more than 99． 5％, dust discharging density is lower than national standard. Filtering bag adopts ladder type flat bag structure which has simple structure, close collocation, high filtering area index, large back-blow swing and dust can be easily shaken off.
This machine can be made into left type and right type in line with different revolving directions of draught. This picture is left type. Materials of filtering bag should be selected in line with performance of the air. Please give clear indication on the order.
