Founded in Sweden by Andrew Piggott in 1994, OAS has been designing and manufacturing advanced Ozone generators and systems. As an expert in ozone solutions, OAS is committed to implementing Ozone technology for environmentally positive solutions at both water treatment and gaseous applications.






Discovered in 1840, Ozone is more effective and environmentally friendly than alternative chemical cleaning agents, especially when compared with chlorine. Since 2000, USDA and FDA have approved ozone for processing food suitable for human consumption. When used correctly Ozone provides a proven, safe and effective method to remove odors, inhibit and stop the spread of mold, while also being extremely effective at killing bacteria and virus.



Main Applications



Ozone generators are used in many different industries for various applications. Below is a non-exhaustive list of applications in which OAS is currently involved.


  • Waste treatment
  • Odor removal
  • Water maintenance
  • Microbiological decontamination
  • Mold remediation
  • Drinking water and purification







Compact and efficient, the range of OAS ozone generator has been designed in order to answer 90% of the requirements of gaseous applications from hotel rooms and car applications to industrial processes such as recycling plants and food factories but also water applications such as swimming pools, aquaculture and so on.
