Refurbished A7K Ozone Generator

Regular price $ 234.99 $ 0.00

7000 mg or 3500 mg/hr ozone output

Over the years, our owner has listened to customer feedback to design our A7K. The A7K includes a remote control to efficiently set up 30 min, 1 hour, 2 hour and 4 hour settings, and most importantly this unit has a REPEAT timer! The unit also features single or dual plate activation for either 3500mg/ozone output per hour, or 7000mg/hr!  This unit is extremely sturdy and well-built and includes a stainless steel handle for easy portability from room to room.  As a general rule of thumb, we recommend replacement plates after either 2 years or 2000 hours of use.  We manufacture the replacement plates which can be viewed by clicking here.

A7K Ozone Generator Countertop

**In Accordance with California Regulations -- This Ozone Generator is Solely for Industrial Use and Must be Installed by a Professional. Potential Health Hazard: Emits Ozone.**

When operating an ozone generator, please remember to remove people, pets, and plants from the area. Do not breathe ozone directly. Ozone can cause lung damage. Be sure to leave the area immediately and only return once the ozone has dissipated. Under most conditions, the treated area will be safe to return to in 12-24 hours after the unit stops producing ozone. Ozone has a half-life of 30 minutes. Ventilate treated spaces or buildings prior to re-entry. Do not use around flammable substances, fuels, or solvents. Some chemical solvents react with ozone and create harmful substances. Do not ozonate a freshly painted room as it can have an adverse reaction with chemicals in the paint. Read the manual before operating the ozone generator.

In case of exposure, remove to fresh air. If inhaled, ozone can damage the lungs.

Please note: Keep away from natural gas, oil, gasoline, or other flammable chemicals as it could be an extreme fire hazard.


No People, Pets, or Plants around ozone!
