Electric filters of type EF

Electric filters of type EF are used for clearing air of aerosols of solid and liquid substances, including oil fog and welding smoke in systems of exhaust ventilation. In some cases cleaning air can be used for recirculation. Filters are operational and keep characteristics at temperature of air not lower than +5°C. Maximum temperature of cleaning air should be 20?C below ignition temperature of trapped liquid and should not exceed 80°C. The ambience and cleaning air should not be explosive and contain aggressive gases and vapours.
