Dust Extraction Systems

Dustkiller - dust filtration system,is a high-efficiency, two-stage electrostatic precipitator, designed, developed and manufactured by powertech pollution controls pvt. Ltd. Bangalore,india.

 features:

this equipment can achieve a high level of dust control in any closed area . Very fine floating particles can be captured before theycan settle down on sensitive precision equipment . It provides high dust capture efficiency. All filter modules are many times washable and re-usableduring the life of the equipment. Maintenance and running costs are low when compared to conventional mechanical filters. We have incorporated safety features such as high voltage fault trip circuitry for reliable , safe and efficient functioning. These systems contribute to a safer ,healthier work environment where toxicairborne pollutants are removed. Weprovide excellent factory support andproduct expertise based on years ofindustrial process emission control.

applications :

dustkiller® can be used for controlling dust and fine particles in any closed room, preferably but not necessarily fitted with window / split typeairconditioners - electronic labs, mechanical precision assembly areas, standards room, metrology labs, pharmaceuticals, bio-tech labs etc. , or wherever dust control® is a necessity. Dustkiller can be quickly installed without major changes in the existing area. How it works: dust and fine particulate matter are sucked in with the air stream by the centrifugal blower  through the inlet on top. These enter the prefilter  where large particles are removed . The remaining fine particles then enter the electrostatic modules where, between a series of parallel aluminium plates, they receive a high +ve charge. These positively charged particles then pass through another series of aluminium plates which are negatively charged. Here, the particles are attracted to the oppositely charged aluminium plates and stick to them just like iron filings are attracted to a magnet, but with one difference - the particles remain adhered to the plates even when the electrostatic filter is switched off. The air, now devoid of particles, escape through the outlet as clean air. The post filter  help in even distribution of air flow through the electrostatic module and also controls odor & smell when filled with activated carbon granules.

The fume  extractor arm is a device which allows the user to position a suction hood to capture fumes or dust close the generation spot with complete ease and flexibility.

 features :

this highly useful accessory may be used with the fumekiller and dustbag  units. Maintenance and running costs are low as all components are built for continous, reliable, safe and efficient use. These systems contribute to a safer , healthier work environment where toxic airborne pollutants are removed. We provide excellent factory support and product expertise based on years of industrial process emission control.

 the extractor arm consists of 2 ducts made of aluminium or stainless steel, connected by pvc flexible hoses and mounted on interconnected support rods with friction-loaded pivots. A suction hood is attached to one end. The other end is attached to a rotating hollow cylinder. The suction hood, ducts, hose and rotating cylinder form a passage for the fumes or dust. The entire arm is self balanced and articulated at 3 points. This allows the suction hood to be positioned by hand at anypoint with a reach of 2 meters (or 4 meters) to & fro and 2 meters ( or 4 meters) up & down with complete ease & flexibility with minimum effort. The extractor arm can be fitted to most of our fumekiller models & dustbag models. The arm can also befitted to overhead ducting to provide suction points close to the floor level for the capture of fumes or dust from pollution generation spots.

 

how it works : the extractor arm consists of elements of aluminium ducts joined by flexible hose, articulated at 3 fulcrum points. One end of the arm is fitted with a swivel fixture. The arm is self balanced using friction pads and a telescopic gas tube. The arm can be swivelled by hand through about 270 degrees and can be positioned easily within a nominal distance specified for each arm. With the extractor arm, fitted to the fumekiller or dust bag the suction hood of the arm is to be positioned close to the fumes/dust generation spot. The fumes/dust will be sucked through the suction hood and will reach the fumekiller or dustbag  for further filtration.

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 dust bag 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.

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 dust bag dust collector can be used in 2 ways. It can be used for pedestral grinders or similar applications where the grinding wheel can been closed 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 dust bag through the suction hood. The larger dust particles in the airstream, after entering the dust bag 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.

Our dust collectors use non-woven, polyester fabrics with antistatic properties, as the dust filtration media. These dust bag filters do not use the electrostatic filtration technique but use mechanical filter media. Suction capacities are available from 425 CMH to 15000 CMH as standard. These dust collectors are used for collecting dust from:

• Tool and cutter grinder
• Cast iron machining
• Buffing
• De-burring & similar operations
• Chip extraction

These dust collectors can be fitted with self-balanced extractor arms of various lengths for added flexibility in capture of dust from generating sources.

Welding fumes can be captured and controlled using specialised welding fume extractors marketed under the brand name Fumekiller™. These fume extractors are available in a wide range of suction capacities starting from 1000 cu mtrs per hour (CMH) to 6000 cu mtrs per hour (CMH) as standard, fitted with our self balanced fume extractor arm. The welding fume extractors work on the principle of electrostatic filtration and can control all types of welding fumes. One large capacity Fumekiller™ equipment may be used for multiple welding stations for the capture and control of fumes. This product is extensively used for removal of fumes from specific generating sources such as:

• TIG/ MIG welding
• Arc Welding
• Plasma Welding
• Soldering
• Dip tinning

These fume extractors are fitted with self-balanced extractor arms of various lengths for added flexibility in capture of welding fumes from generating sources.
Centralised fume extractors can be supplied upto 1,00,000 CMH suction capacity in modular form.

For clean room applications, electrostatic filter modules are available with air flow capacities of 500 CMH, 2000 CMH, 3000 CMH and 4000 CMH per module. These can be stacked together for catering to large air flow requirements and at the same time retain the efficiency of electrostatic filtration. The high voltage power pack can be mounted at a remote location. These modules can be retro-fitted to existing mechanical filter units to improve the filtration efficiency without change in suction fan power requirements.
we can provide upto class 100000 dust controlled rooms witout the use of airconditioning or hepa filters.
these filter modules are ideal for use as  prefilters for higher than class 1,00,000 clean rooms, saving electricity and extending the life of the terminal hepa filters by over 3 times.
