  • Filter modules are washable, reusable.
  • No replacement required.
  • Safety features incorporated for reliable and efficient working.
  • A safer, healthier working environment where hazardous fumes and airborne contaminants are removed.
  • Complete factory support and product expertise based on years of industrial process emission control.

Usage
Fumekiller can be used for removal of fumes, smoke & fine dust, from Welding, EDM, Induction hardening, Ink spray, Heat treatment, Oil quenching, Wire drawing, Annealing, Soldering, Dip tinning, Wave soldering, Rubber curing, Die casting, Oil mist, Coolant mist, Diesel gensets. Fumekiller can also be used for capturing fine powder from tabletting, capsuling and finishing operations.

How It Works
Particles in fumes, smoke & dust stream enter the electrostatic filter through the suction inlet (1). Particles carried by the air stream first enter the Pre-Filter (2) where large particles are removed. The remaining particles then enter the electrostatic module (3) 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, escapes through the outlet (5) of the system as clean air. The Post Filter (4) evenly distributes the air flow through the electrostatic modules. Post filters when fitted with activated carbon granules can control odour & smell. Suction is provided with a centrifugal fan (6)


DUSTKILLER


Air flow capacity-500 CMH, 1000CMH.For removal of atmospheric dust in an enclosed area,for general cleanliness levels.This system when used in a closed room,with or without air conditioning,can bring down the dust level by more than 85% of previously existing dust levels.
DustKiller - Dust filtration system, is a high-efficiency, two-stage electrostatic precipitator, designed, developed and manufactured with suction vom by Powertech Pollution Controls Pvt. Ltd, Bangalore, India, with built-in fan blower used for control of atmospheric dust in closed rooms.

Feature

  • Captures fine particulates before they settle down on precision equipment.
  • High filter efficiency.
  • Low electrical running cost.
  • No replacement of electrostatic module.
  • High reliability and easy maintainance.
  • Complete factory support from engineering professionals, based on years of expertise in industrial pollution.

Usage
DustKiller can be used for controlling dust and fine particles in any closed room, preferably but not necessarily fitted with window/split type airconditioners - electronic labs, mechanical precision assembly areas, standards room, metrology labs, pharmaceuticals,bio-tech'labsetc. 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 (1) through the inlets (2) on top. These enter the prefilters (3) where large particles are removed. The remaining fine particles then enter the electrostatic module(4) 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, escapes through the outlets (5) as clean air. The postfilters (6) help in even distribution of air flow through the electrostatic module.

Dust and Fumes control using Electrostatic Filtration
These Filter Modules are high-efficiency, twostage electrostatic filters, designed, developed and manufactured by Powertech Pollution Controls Pvt. Ltd., Bangalore.

Feature

A safer, healthier working environment where harardous fumes and airborne contaminants are removed.

  • No replacement of the electrostatic modules for the lifetime of the equipment.
  • Low running cost. High filter efficiency, low pressure drop.
  • Can be incorporated into existing air flow systems with minimal effect on the overall pressure or air flow capacity of the system.

Applications
These modular filters are used for custombuilt applications & can be added module by module to suit various air flow rates. These modules are used as primary filters for Class 100,000 Clean Rooms & as Prefilters for higher Class levels of Clean Rooms. When used as pre-filters for higher class levels, they can increase the life of the terminal filters. The total pressure drop as compared to conventional pre-filters is negligible. These filters can be used in a centralised system for removal of fumes, smoke, oil mist, coolant mist, dust and fine powders from many in - plant industrial processes which generate pollutants rendering the shop floor unhealthy.

How It Works
Each filters module can handle an air flow rate as specified. The required quantity of modules are placed in an MS painted enclosure. The air inlet side is placed in the air stream using a suitable adaptor ducting. The power pack feeding the electrostatic voltages to the Modules is separately mounted in a control panel near the MS enclosure with the electrical connections made through conduits. Prefilters and post filters are placed before and after the electrostatic filter modules. Dust and fine particulates are sucked into the filters modules with the air stream. These first enter the prefilters which prevent large particles entering the Modules. The fine particles then enter the Modules where, between a series of parallel aluminium plates, they receive a high positive charge, The positively charged particles then pass through another series of negatively charged aluminium plates. Here, the particles are attracted to the oppositely charged plated and stick to them like iron filings to a magnet, but with a difference - the particles remain adhered to the plates even when the electrostatic filter is powered off. The clean air, devoid of particles, escapes through the after filters. The post filters help in distribution of the air flow through the electrostatic filter modules.


DUST BAG FILTERS


We also manufacture Filters using non-woven filter fabric as the filter media. These have been developed for collecting dust from Tool and Cutter Grinder, Cast Iron Machining & can also be used to collect dust from Buffing, deburring & similar operations.Please note that these Dustbag filters are not the electrostatic type.

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.
