Electrostatic Filtration System, Fume Killer

Powertech Pollution Controls Pvt Ltd has designed, developed and manufactured a Fume Killer – an Electrostatic Filtration System that is a high-efficiency two-stage electrostatic precipitator. Usage: Fume Killer can be used for removal of fumes, smoke and fine dust, from welding, EDMs, 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, etc. Fume Killer can also be used for capturing fine powder from tab letting, capsuling and finishing operations. Operation: particles in fumes, smoke and dust stream enter the electrostatic filter through the suction inlet. Particles carried by the air stream first enter the Pre-Filter where large particles are removed. The remaining particles then enter the electrostatic module 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 of the system as clean air. The post filter evenly distributes the air flow through the electrostatic modules. Post filters when fitted with activated carbon granules can control odour and smell. Suction is provided with a centrifugal fan.
