Improve your working environment

– OxySan™ is an effective air cleaner which, by means of ionization, ensures that your workplace has a healthy air quality.

Particularly suitable for garbage rooms

– OxyClean™ is an ionization unit that effectively removes strong odors, mold, particles and dust.

Effective technology

The ions react with pollutants and odors, making suspended particles
electrically charged which makes them fall to the floor or can be more easily trapped in filters. The result is a clean and fresh air environment that is perceived to be cooler and fresher. Mold growth is prevented while the area feels healthier. Only 5 minutes of bipolionization with the correct ionization level, results to the relative particle content being reduced by up to 95%.
