The heavy-duty electrostatic filter

The combination of mechanical and electrostatic filtration puts EFO in the front line of electrostatic filtration technology, especially suited for rough applications such as coolant mist and smoke. The EFO requires a minimum of service. All filter elements can be washed and this is easily carried out by own personnel. Filter elements can be reused year after year, without cost for buying replacement filters. For easier and faster service an extra set of collector cells are used to limit down time on the filter system.
