● Electrostatic filters do NOT use any physical filter material such as paper, cloth,  fibre etc. to capture fine particles

● It uses a high voltage electrostatic charge between a series of aluminium plates instead , to first charge floating particles as small as 0.01 micron  (1 micron is 1/25,400th of an inch ).

● The positively charged particles are subsequently collected on negatively charged aluminium plates

● Clean air devoid of particles is sent out of the filter .

● The efficiency is between 95% to 100% for various particulates.

How Electrostatic filter works:

5

Features of Electrostatic Filters: The Filters are permanent , many times washable and reusable there by eliminating the replacement cost for filters .

• The filters can capture particles as small as 0.01 micron as compared to just 5 microns in standard filters. Thus Fumes such as cigarette smoke, welding fumes, etc can be captured, which standard filters cannot do .

• The power consumption is upto 40% lower than when using standard filters.

• The filters can be used for recovery of oil and coolant fumes in CNC machines, and the recovered oil or coolant may be reused giving considerable savings .

• Pressure drop across these filters is very low . 6

Electrostatic Filterter Vs Conventional Filter

Conventional filters (synthetics) Electrostatic filters

1 Pressure drop across the filters is higher, typically, 25mm WG

Pressure drop is substantially lower, typically, 3mm WG

2 Requires higher wattage of motor / blower, typically, 500W per 1000CMH of air flow

Substantially less wattage of motor/blower, typically, 250W per 1000CMH of air flow

3 Replacement cost, of periodically changing the filters when they are saturated

No replacement cost as filters are for the lifetime of the equipment. Can be cleaned when saturated repeatedly

4 No indication when filters are saturated leading to motor burnout, due to loading of the motor

Automatic Indication with trip circuitry when filters are saturated. Motor burnout avoided

5 Filtration limited to particulate size of 5 microns or greater, in general

Particulate sizes upto 0.01 micron can be filtered with excellent efficiency

6 Cannot reclaim oil/coolant after filtration Ideal for reclaiming of oil/coolant with good efficiency

7 Electricity running cost is higher as motor wattage is higher

Lower electricity running costs upto 35% lower7

Applications• These modular filters are used for customer built applications & can be added module by module to suit various air flow rates.

• Used as primary filters for class 100,000 clean rooms & as pre-filters for higher class levels of clean room where they can increase the life of the terminal filters.

• Can also be used in a central 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. 14

Technical Specifications - DustBag

• Motorised de-dusting can be incorporated

18

● The extractor arm is self balancing and articulated at 3 points.

This allows the suction point to be positioned by hand at any

point with a reach of 2 meters(or 4 meters) to and fro and 2

meters ( or 4 meters) up and down with a complete ease &

flexibility with minimum force .

● The Extractor Arm can be fitted to most of our Fumekiller

models & dust bag models. The arm can also be fitted to

overhead ducting to provide suction points close to the floor

level for the capture of fumes or dust from pollution

generating spots. 19
