O3M was born in 1984 in the womb of the MAINO INDUSTRIES company to meet its own needs for sanitizing eggs incubated in Incubator and Hatcher machines, with the least impact on the environment, instead of disinfection with Formaldehydes in use up to that moment.

At the beginning, the design and construction of ozone gas generators was based only on the needs described above, and then became, over the years, an international reference point in natural and ecological organic treatments for the most varied applications.

Today, more than thirty years after its opening, O3M by MAINO has gained considerable experience and moves freely in the local and world market to meet the needs of many applications, both from the private and public sectors, but also from industrial, manufacturing, chemical, food, military, pharmaceutical, etc. etc. sectors.

O3M by MAINO has in its catalog a complete line of autonomous devices, intended for the treatment of both air and water, to deodorize, disinfect, sterilize and sanitize in the most disparate scopes. 

In addition to these machines, O3M by MAINO is always available to design and build machines to meet specific requests and ad hoc applications, for any sector.
