Fighting Tobacco Smoke

Designated smoking areas, althrough typically spared from working and living spaces, often cause problems with air that may very well circulate in and out of these areas. The smoking area itself may be overwhelmed with cigarette smoke, causing smokers to seek alternative places to smoke.

Sanuvox Technologies offers two units that are effective at removing tobacco smoke from the air and reducing cigarette odors, as well as nicotine and smoke that are so problematic. Unlike conventional technologies, Sanuvox UV systems do not use costly carbon for absorption nor rely solely on filters, which easily become coated with tar and nicotine The proprietory process changes the molecular structure of the tobacco smoke into a fine powder, which is then captured on the filter media. It is recommended that the UV systems be sized to provide a recirculation rate of 6 to 8 air changes per hour.

THE EQUIPMENT

Stand-alone Sanuvair® 300 VOC or Sanuvair® 1000 VOC UV air purifiers that include germicidal and oxidizing ultraviolet lamps, prefilters and a main filter to capture nicotine and smoke. An optional VOC (Volatile Organic Compound) detector can be used with multiple lamps when the number of occupants increases.

Typical installation:

OPERATING THE EQUIPMENT

Sanuvox dual zone UV lamp will reduce odors, nicotine and smoke in the room through recirculation. With the optional UV-V lamp(s) and VOC detector, if the smoke level increases (because there are more smokers), the VOC detector will trigger the additional oxidizing lamp(s), then shut them off when the level decreases. The cycle is repeated, lowering the odor, nicotine and smoke levels, until the maximum reduction is reached.

UNDERSTANDING THE CHEMISTRY
Cigarette smoke is composed mainly of:

  • White ash
  • Nicotine molecules
  • Chemical by-products

Ash will be trapped by the pre-filters. Nicotine will be transformed into a type of yellow powder that will be captured by the prefilters and the main filter. The chemical by-products will be oxidized by the UV process: high frequency UV-V energy activates the organic molecules and accelerates the chemical reaction, resulting in the air being oxidized. Odors are oxidized by the process of photolysis that initiates the breaking of chemical bonds by the action of the ultraviolet light. The oxidation process will reduce odors and chemical contaminants by changing the complex molecular contaminants into CO2 and H2O

SIZING THE EQUIPMENT

Approximately 6 to 8 air changes per hour are required. This reduces the standard of fresh air required by two thirds.

An Sanuvair® S300 VOC unit (300 cfm) will be sufficient for a 1,920 cu.ft. room (12’ X 20’ X 8’) with 9.3 changes per hour.

An Sanuvair® S1000 VOC unit (1000 cfm) will be sufficient for a 9,600 cu.ft. room (20’ X 40’ X 10’) with 7.5 changes per hour.

WHERE TO INSTALL

Many buildings and facilities can be equipped with one of these stand-alone units, like eldercare homes, private homes, poker rooms and casinos, bingo halls, cigar bar, or smoking rooms.
