Close coupled field technology when used in conjunction with electrostatic filtration can eliminate potential pathogens in the air, according to a press release from UK company Air Scientifics Equipment. The equipment generates a high voltage field which induces an altered oxygen state which can destroy bacteria, viruses and fungi.

The system incorporates a high efficiency filter interposed in the exhaust stream to remove ozone and particulates, which is necessary to comply with European emission regulations. Studies have shown that the combination of CCFT and HAF will remove pathogens, ammonia and volatile organic compounds in an enclosed area. The system would have application in egg coolers and vaccination preparation rooms in hatcheries and even chick handling areas.


The combination of the two technologies has potential to improve the environments of medical facilities, pharmaceutical plants and situation where a high degree of air purity is required.
