Dust bag, dust collectors ,are fitted with Nonwoven polyester fabric capable of capturing dust particles as small as 10 microns and are designed, developed and manufactured by Powertech Pollution Controls Pvt. Ltd., Bangalore.

Feature

Removes harardous dust.
Fitted with manual de-dusting arrangement for in-situ dusting of filter bags.
High filter efficiency of 98%.
Can be fitted with anti-static, or fireretardant filter fabric, if required.
Separate dust collection bin for easy disposal of dust.

Applications

Dust bag, dust Collectors can be used to capture dry or mildly wet particles from tool & cutter grinders, cast iron machining, graphite / carbon machining, surface grinders, drilling, milling, deburring, polishing,
mixing, etc.


How It works

The DustBag dust Filter can be used in 2 ways. It can be used for pedestral grinders or similar applications where the grinding wheel can be enclosed upto 70% with a specially designed mild steel suction hood. The hood has an outlet to which a PVC flexihose is connected. The other end of the flexihose is connected to the inlet of the DustBag. It can be used for surface grinders, CNC machining, or similar application where the wheel or machining tool cannot be enclosed. In this case a rectangular suction hood can be placed in the stream of the dust particles near the grinding wheel edge or machining tool edge. During the dust generation process, dust particles are drawn into the DustBag from the suction hood. The larger dust particles in the airstream, after entering the DustBag fall to the bottom collection tank immediately. The finer dust particles reach the filter bag and are trapped there. The clean air leaves the DustBag from the top. The filter bags can be de-dusted using the lever at the side which when shaken vibrates the bags which are spring-mounted. It is not neccesary to remove the bags for cleaning.
