The booster fan is a great way to increase ozone production and distribution. It improves results, efficiency, and long-term performance. It's the ideal size, and fan speed for our ozone machines. It has cloth blades that are easy and safe to use. The best part - it easily rotates upwards to help blow ozone higher into the room. Reminder: ozone is heavier than oxygen and tends to drop. So it's best to shoot for the ceiling. Placing this fan near the outlet end of our ozone machines (where the ozone comes out) and facing it in the same air flow direction helps to pull more oxygen through the machine which creates a higher concentration of ozone. Increasing the rate of ozone production and distribution has many valuable benefits both short and long term.
