The Fly Killer Arc 4000, unlike many other budget priced machines, uses a 4000 volt high voltage grid to exterminate flying insects. The unit is suitable for use in restaurants, kitchens, food shops or any other locations where flying insects pose a problem. After the insects have been attracted by the high output UVA lamps and killed by the high voltage grid, they can be quickly and hygienically disposed of in the large catchment tray.
