Working Principle

There is a reel of new filter material in the auto-winding filter’s filter material box, when the dusty air with big blast capacity was brought into the auto-winding filter by outside force, the filter initial resistance will be increased as per the filter dust increased, when the filter resistance increased to the design final value, the differential pressure switch opened, the switch signal input the control process, starting the dynamo automatically, filter material reel is winding as per dynamo operation, so the dirty filter material is winding, at the same time the filter face is changed to be the new filter material. Until the whole reel of filter material used out, the changed position of handle switched off the limit switch of the filter material box, the filter material alarm(red light) lights up, it means to changed a reel of new filter material.
First class pre-filter stage of industrial ventilation and air conditioner ventilation system
Working condition: High dust load, changed the filter material more often
Operation system: Constant blast capacity
