The Sonozaire AS34 is the industry-standard 115A ozone generator that fire and smoke restoration contractors, mold remediation specialists, and biohazard cleanup teams reach for when odor has to be eliminated rather than covered up. Sonozaire has built ozone generators for the restoration industry for decades, and the 115A is the small-format unit that most restoration contractors keep multiple copies of in the warehouse for residential and small-commercial jobs.
Built for
Fire and smoke restoration contractors who treat fire-damaged residences, smoke-damaged commercial spaces, and contents-restoration chambers. The 115A is the sweet spot between a small consumer unit and a large industrial generator - portable enough for one person to carry into a residence, powerful enough to treat a full residential floor or a 1,700 cu ft restoration chamber.
Mold remediation specialists running odor cycles after physical removal is complete. Ozone oxidizes the volatile compounds that produce mold odor and complements (does not replace) physical remediation following IICRC S520.
Biohazard cleanup teams after decomposition, blood, and trauma scene cleanup. Ozone is the industry-preferred odor eliminator for sealed spaces after physical cleaning, because it leaves no chemical residue and reaches odor sources that fogging cannot.
Property managers and rental operators running between-tenant odor cycles on cigarette, pet, and cooking odors before re-rental. The unattended operation lets the unit run overnight in a sealed unit without supervision.
How ozone works
The Sonozaire 115A pulls in ambient air, passes it across a high-voltage corona that converts a portion of the atmospheric oxygen (O2) into ozone (O3), and discharges the ozone-enriched air through a built-in blower at 60 CFM. The ozone reacts with the volatile compounds that produce odor - oxidizing them at the molecular level rather than masking them with fragrance. After the cycle ends, the ozone naturally decays back to ordinary oxygen within hours, leaving no chemical residue.
Capacity and run time
The 115A is designed for restoration chambers approximately 1,700 cu ft (48 cubic meters) and for on-site restoration of spaces 2,500 to 15,000 cu ft (70 to 425 cubic meters). Practical run times range from a few hours for light odor sources in small spaces to 24-72 hours for heavy fire and smoke damage in larger spaces. Always seal the treated space, post warning signs, and follow IICRC S700 safety protocols for unoccupied spaces during the treatment cycle.
Construction
The 115A cabinet is heavy-duty aluminum, 22 x 20 x 7.5 inches, weighing 32 pounds. The aluminum construction stands up to the corrosive environment of an active ozone generator while keeping the unit portable enough for one-person handling. The blower is 60 CFM and the unit draws 70 watts at 115V single-phase - low enough power consumption to run on any standard outlet without dedicated circuit. Optional 220-240V configuration is available for international or industrial installations.

Frequently asked questions
What is the difference between the 115A and the larger Sonozaire models?
The 115A is sized for restoration chambers up to about 1,700 cu ft and on-site work in 2,500 to 15,000 cu ft. Larger Sonozaire models (220, 330, 440 series) treat larger volumes per cycle. Most restoration contractors run a small fleet of 115A units for typical residential and small-commercial work and reserve the larger models for major fire or smoke jobs.
How long does an ozone treatment take?
Treatment time depends on the source odor, severity, and air volume. Light cigarette odor in a small office may clear in a few hours. Heavy fire or smoke damage in a residence may require 24 to 72 hours of unattended run time. Always check IICRC S700 guidelines and follow safety protocols for unoccupied spaces.
Does ozone leave a residue?
No. Ozone (O3) reverts to ordinary oxygen (O2) within hours of the generator being turned off, leaving no chemical residue. That is a primary advantage over fogging chemistry for occupied-space restoration work after the cycle completes.
Is the space safe to occupy after treatment?
After the generator is shut off and the space has ventilated, ozone naturally decays to oxygen. Industry practice is to ventilate the space for at least 30 minutes after the cycle ends and verify with an ozone monitor before re-occupancy. The treated space is safe for occupants once ozone has fully decayed.
What odors does ozone treat?
Smoke (cigarette, fire), mildew, mold odor, pet odors (urine, dander), cooking odors, decomposition odors after biohazard cleanup, and chemical odors after fires. Ozone oxidizes the volatile compounds that produce odor at the molecular level rather than masking them with fragrance.
