DÖLCO Ozone Generator OZ4

High-performance ozone generator 40,000 mg/h for professional odor neutralization and remediation — Made in Germany

Where ventilation, wiping, and classic cleaners reach their limits, the DÖLCO Ozone Generator OZ4 steps in: With an ozone production of 40,000 mg/h (40 g/h), the device actively generates ozone from the ambient air via corona discharge — no separate oxygen connection is required. Ozone penetrates areas that sprays and cloths cannot reach, neutralizing odor molecules at the source rather than just masking them. This makes the OZ4 the tool of choice for professional remediation and odor neutralization: after water damage and mold infestation, for fire and smoke odors, in vehicles, basements, and sanitary rooms, as well as for eliminating stubborn nicotine odors. The robust stainless steel housing, the freely adjustable timer from 1 minute to 99 hours, and the optional flow rate of 205 m³/h make it a reliable companion for trade, facility management, and building cleaning. Important safety notice: Ozone is harmful to health in high concentrations. The OZ4 is a professional ozone generator and must only be operated in unoccupied, empty rooms without people, animals, or plants — ventilate thoroughly afterwards. It is NOT to be confused with DÖLCO HEPA air purifiers, which are designed for continuous operation in occupied rooms.
