The system is designed for light industries. It is simple,efficient and operator friendly. The collected dust particules are dislodged by shaking manually through mechanism that link to the filters. Rong Fong’s articulated arm with noise damper can be adapted easily and meet the Government Environment Control Regulations.

The system operates in the same manner as Model BFH-M The finer dusts particles are dislodged automatically by motorised vibrations set off periodically by programmed timer. The operation can carry on continuously by incooperating a rotary valve and screw-drive system for transferring the collected dusts to outside for disposal without the need of an operator. It has a huge capacity and is very efficient-rate 250 m3/min.
