Ozonetek offers ozone generators for air treatment with capacities ranging from 100 mg/h several hundred g/h. The low capacity ozone generators are air fed ozone generators, whereas higher capacities in the range of 10 g/h and above are oxygen fed ozone generators. The oxygen is provided using oxygen concentrators procured from the market. The 100 mg/h and 200 mg/h ozone generators for air treatment have in-built mini air recirculation fans which take in ambient air from the surrounding and give out air with a small percentage of ozone in it. These can be mounted on the wall or on shelves at a height not less than 8 ft. from the floor.

The larger than 200 mg/h ozone generators for air treatment are provided with built-in mini oil free air compressors and which give out very low concentration ozone output from a PTFE tube for injecting directly in an air handling ducting. From here, ozone mixed with air is distributed in the area catered to by the air handling unit through the existing ducting.
