BRISTOL Electrostatic Filters
BRISTOL T&G International GmbH

What is an electrostatic filter?

Filtermist provides a range of high-quality Electrostatic Filters, designed and manufactured by German sister company Bristol T&G. Electrostatic filters work by electrically charging oil mist particles, which are then attracted onto oppositely charged collector cells. Typically used on applications creating large amounts of heavy oil smoke, the collector cells can be banked together to increase their efficiency and capacity. Each system in our range comes in single or double pass configuration.

Whilst there are no consumable filters, the cells do need to be regularly cleaned in order to maintain optimum performance.
