Dust Bag® , dust collectors, are fitted with Non-woven polyster fabric capable of capturing dust particles as small as 10 microns
and are designed, developed and manufactured by Powertech Pollution Controls Pvt. Ltd., Bangalore, India.
Features
This equipment can capture large quantities of dust from any generating source with high capture efficiency . The DustBag® uses non-woven polyester cloth as the filter media . We can incorporate additional safety features such as pressure differential switch , fire retardant as well as antistatic filter media , etc , as optional accessories. These systems contribute to a safer , healthier work environment where toxic airborne pollutants are removed. We provide excellent factory support.

How it Works
The DustBag® dust collector 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 suction hood. It can also 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 facing 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® through 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 filter bags can be de-dusted manually or automatically (option). It is not necessary to remove the bags for cleaning.

Dust Bag® Reverse Pulsed Jet
DustBag® Reverse-Pulsed-jet(RPJ), is a trademarked,high-efficiency dust collector with reverse-pulsed-jet cleaning system for the filter cartridges, designed , developed and manufactured for the control of most types of dust , both fine and coarse ,generated during machining operations and processes on the shop floor
Features
DustBag® Reverse-Pulsed-jet(RPJ) is an air pollution control equipment, which can capture large quantities of dust , from any generating source, with high ® efficiency.The DustBag® uses polyester non-woven Easyfit cartridges with filtration capability of 3 micron and larger with 99% efficiency. The Reverse-pulsed-jet cleans the cartridges continuously during operation without shutting down the DustBag® operation. Optional accessories such as motorised rotary air lock, spark arrestor with or without water cooling, differential pressure switch, pressure release valve and dust collection trolley, may be provided.
Applications
The equipment can be used effectively for the capture and control of dust, in large quantities, from most dust generating operations . The DustBag® does not require periodic shutdown for de-dusting of the filter cartridges . Specific applications are – capture of dust from the machining of graphite and carbon components , ceramic and talcum dust . It may also be used in dust-capture applications where the dust collector is to be working continuously with only short breaks , if at all . The collected dust may be re-used , if required. Since the filter cartridges are cleaned continuously by the pulsed air-jet , operation is hands-free , except for the removal of collected dust for disposal
How it Works
The built-in suction fan driven by an induction motor provides a powerful suction which sucks the dust into the DustBag® Reverse-Pulsed-jet(RPJ) . The dust as small as 3 micron and larger is filtered by the polyester non-woven filter cartridges with 99% efficiency. The clean air is released through the suction fan outlet fitted with a silencer for noise reduction . The continuous cleaning system which de-dusts the filter cartridges , uses compressed air at 5bar to 8bar (to be provided by the customer at site) in pulsed jets into each filter cartridge through a set of solenoids fired by an electronic sequential timer . The pulsed air jets clean the cartridges continuously . The dust falls into the tapered collection bin and is removed through a rotary air lock into a trolley . The collected dust may be disposed as required.
