Electrostatic Precipitator
Span Filtermist is very proud of being the only company in India manufacturing CE Certified ESPs and Vertical ESPs.Over the period of last 12 years, Span Filtermist India Pvt. Ltd. has installed many Electrostatic Precipitators all over India, catering to a variety of customer needs and providing cost effective solution for oil mist and dry smoke problems on various metalworking (metal-cutting & metal-forming) and heat treatment processes / applications.
These charged particles then enter the COLLECTION CELL where the ground plates collect the particles by virtue of electrostatic forces. An AFTERFILTER improves air distribution and collection efficiency by trapping any agglomerated contaminants, which might blow off the cell.
Working of Electrostatic Precipitator :
When contaminated air is drawn into the precipitator through the suction hood, large particles are first filtered in an inlet pre collector, then it passes through an additional pre-filter to ensure even air distribution and uniform particle size across the area. Then it passes through the IONIZER, where it is subjected to an intense electric field, which electrically charges all the particles in the contaminated air stream.Power to the Ionizer and collecting cell is supplied by an effective high voltage POWER PACK. A Safety Switch (Limit Switch) installed on the main cabinet, disconnects the electrical supply to the power pack once the door to the collection cell is opened with the ESP unit still 'on'. The Blower is mounted on clean side of unit, which virtually eliminates all the blower related maintenance activities. The indicating lamps on the control panel indicate the status of the unit.

Important Features of Our Electrostatic Precipitators :
- The Electrostatic Precipitators are suitable for industrial application such as metal machining processes especially where neat oil is used as coolant and to extract welding fumes etc.
- The Vertical Electrostatic Precipitator has a small foot print and is the ideal solution to industrial fumes / mist problem where there is industrial shop floor space constraint.
- It serves more than 95% industrial fumes / mist extraction purpose due to its high filtration efficiency.
- Compact and sturdy design ensures long life.
- Less power consumption.
- It is safe because of its built and safety features.
- It is very easy to install and maintain.
- The blower of our ESP is always mounted on the cleaner side of the unit which virtually eliminates all the blower related maintenance activities.
- Dedication to quality and prompt after sales service ensures optimum performance of all our Electrostatic Precipitator.

Some Important Safety Features
Span Filtermist Electrostatic Precipitator is equipped with a unique Power Pack coupled with safety switch (also called as limit Switch), which is installed over its main cabinet, that quickly disconnects the electric supply to the power pack in case the door to the collection cell is left open while the ESP unit still being switched on.
Indicating lamps mounted on the control panel of the unit indicate the status of performance as mentioned below:
- H. T. on - Green Light
- DC off / Dust Saturation - Red
- Door remains open - Amber
- Blower on - Green light
- Overload fault - Red
