The High Efficiency UV-C / UV-V air purifier destroys chemical & biological contaminants including chemical odors. R3500X sanuvox technologies inc.

5. Two Factors in achieving a high bacteria kill are : a)The INTENSITY of the UV source and The greater the INTENSITY the greater the kill. b)The length of TIME the bacteria is exposed to the UV light The more TIME the bacteria is suspended in front of the UV light, the higher the UV dosage it receives, The more TIME the bacteria is suspended in front of the UV light, the higher the UV dosage it receives, the greater the kill. sanuvox technologies inc.

6. The R3500X achieves a high intensity through the use of Reflection. The R3500X achieves a high intensity through the use of Reflection. The same way a flashlight or car's headlight uses a reflector to intensify and direct light. The The same way a flashlight or car's headlight uses a reflector to intensify and direct light. The Sanuvox UV air purifier uses an aluminum reflector tube to intensify the UV energy.

7. How does Sanuvox slow the bacteria down so it can receive the UV dosage needed to kill it? How does Sanuvox slow the bacteria down so it can receive the UV dosage needed to kill it? The turbulator slows, twists and mixes the air around the lamp, dramatically increasing the time The turbulator slows, twists and mixes the air around the lamp, dramatically increasing the time the contaminants are suspended in front of the lamp. the contaminants are suspended in front of the lamp. That's what Sanuvox does. It slows down the air so the contaminant can be burned by the UV That's what Sanuvox does. It slows down the air so the contaminant can be burned by the UV energy. The more time in front of the lamp, the higher the UV dosage the contaminant receives, energy. The more time in front of the lamp, the higher the UV dosage the contaminant receives, and the higher the kill. and the higher the kill. The more time in front of the UV energy, the higher the kill. Very similar to putting your hand over a candle. If you were to quickly move your hand through the flame, you would barely feel the heat. Should you move your hand slowly through the flame, you would surely be burned. sanuvox technologies inc. Dwell Time

8. Finally, to increase the dwell time (the time the contaminant is in contact with the UV energy), the Finally, to increase the dwell time (the time the contaminant is in contact with the UV energy), the purifier is mounted parallel to the air-stream, not perpendicular, maximizing the time the contaminant purifier is mounted parallel to the air-stream, not perpendicular, maximizing the time the contaminant is in contact with the UV lamp. is in contact with the UV lamp. If properly delivered, UV irradiation can be a very efficient method for air purification. The use of the If properly delivered, UV irradiation can be a very efficient method for air purification. The use of the turbulator, aluminum reflector tube, turbulator, aluminum reflector tube, J Lamp and placing the unit parallel to J Lamp and placing the unit parallel to the air-stream are the tools needed to the air-stream are the tools needed to maximize the UV energy. maximize the UV energy. Parallel = Increased Dwell Time Perpendicular = a fraction of Dwell Time of Dwell Time sanuvox technologies inc. Dwell Time The air spends 2400% MORE TIME in Contact with the UV energy than does a probe (free standing) purifier.

9. There is a big difference between the UV that can be seen and effective UV. Although UV light can shine for a great distance, that light has virtually NO germicidal effect on moving air. Only the UV within a couple of inches of the lamp is effective in treating moving air. The rest is lost within the duct. The two inch rule only applies to air purification (treating moving air). When treating moving air, there is only a fraction of time to treat the contaminant in the air-stream. Thats why an air purifier needs an intense amount of UV energy. In contrast, the two inch rule does not apply to object purification (purifying a stationary object). The object is not moving therefore the need to deliver such high amounts of UV within a fraction of a second is no longer needed. The UV energy can shine on the object indefinitely. Light from our Sun can be seen here on Earth, but not nearly as powerful as it is in space. sanuvox technologies inc. The Two Inch Rule
