Disinfecting Locker Rooms & Bathroom Odors

Disinfecting Locker Rooms and Bathroom Odors

Lockers room odors are the result of perspiration which is excreted by the sweat glands in our skin. Sweat itself is not the source of the odor, but rather the off-gassing of the bacteria which feeds on sweat. The source of this unpleasant off-gassing can be found on occupants, clothes, towels and equipment as well as other soft materials.

The Sanuvair® S300 air purification system with HEPA filter is the ideal solution to reduce and elimitate unpleasant odors, such as in locker room and bathrooms. The proprietary Sanuvox process sterilizes and oxidizes bacteria, viruses, chemicals and odors, dramatically improving the air quality.

As stand-alone units, the P900 is equipped with a blower of 80 cfm, the Sanuvair®S300 with a blower of 300 cfm, and the Sanuvair® S1000 with a blower of 1000 cfm. Filters (except on the P900) capture particulates (pet hair, etc.) while the dual zone UV-C/UV-V “adjustable” lamp disinfects the air.

The Sanuvair® S300 unit can be used as a stand-alone with optional intake and exhaust louvers or ducted using an 8-inch flexible duct with optional collars.


Untreated air is drawn into the inlet of the unit, purified with the germicidal / oxidation UV lamp, filtered and then exhausted. Recirculating the air in the room continuously reduces bacteria and odors, improving overall air quality.


Approximately 6 to 8 air changes per hour are required.

A P900 unit (80 cfm) with a dual zone UV-C/UV-V lamp will be required for a 1,200 cu.ft. room (15’ X 10’ X 8’).

A Sanuvair® S300 unit (300 cfm) with a dual zone UV-C/UV-V lamp will be required for a 4,500 cu.ft. room (25’ X 20’ X 10’). Collars can be ordered to duct the unit using an 8-inch diameter duct, or an intake and exhaust louver grill(s), if the unit will be used as a stand-alone system.

A Sanuvair® S1000 unit (1000 cfm) with a dual zone UV-C/UV-V lamp will be required for a 15,000 cu.ft. room (50’ X 20’ X 15’). The system uses 2 x 8 inch inlets and 2 x 8 inch exhaust outlets (collars).

The unit should be positioned near the center of the room to be as effective as possible. Excluding the P900 unit, the two other units can be installed in the plenum above the ceiling or in an adjoining room and ducted with 8-inch round duct.

All Sanuvox air purification systems are equipped with a dual zone “J” UV-C/UV-V lamp. All dual zone lamps have a maximum oxidizing UV-V section in order to minimize residual ozone. In situations where odors are more concentrated, it is possible to outfit the units (except in the P900 unit) with special lamps incorporating a larger section of oxidation, with the installer making the final odor adjustments on site.

Many buildings and facilities can be equipped with one of the stand-alone units, like team sport locker rooms, dressing rooms, fitness centers, laundry rooms and storage, or basements.

Purifying Air & Destroying Airborne Bio-Contaminants

Purifying Air and Destroying Airborne Bio-Contaminants

It is not uncommon for outside contaminants, including odors and allergens, to find their way migrating into a building. Restaurant odors, manufacturing off-gassing, diesel fumes from idling trucks, and even jet fuel from helipads can be pulled into the make-up air and distributed throughout the HVAC system and building.

Sanuvox Technologies line of in-duct UV air purification systems are the ideal solution for these often troublesome issues. Sanuvox offers exceptionally cost-effective systems that can address IAQ issues that filters and absorption media cannot. The proprietary system eradicates biological contaminants such as mold, bacteria, viruses, germs and allergens; reduces chemicals, VOCs and biological odors. Installed PARALLEL to the air-stream results in greater « dwell time » between the air and the UV lamps.


The duct-mounted units are installed in the return or supply side of the HVAC system parallel to the airflow, and are supplied with multiple germicidal UV-C lamps, each with a section of oxidizing UV-V that can be adjusted (covered or removed) depending on the concentration of odors.

Typical installation on the HVAC return side:


The UV lamps disinfect the recirculating air in two ways:
1. The oxidizing UV-V section of the lamp reduces the chemical components in the air through photo-oxidation. The selected units are designed to be “dosed” on site according to the need.
2. The germicidal UV-C section destroys airborne biological contaminants (viruses, bacteria, mold).


The ultraviolet photon energy (170-220nm) is emitted from a high-intensity source to decompose (break-down) oxygen molecules into activated monoatomic oxygen. The rate of production or effectiveness of this process depends on the wavelength and intensity of its source.

The activated oxygen atoms (O*) are then mixed in the airstream; the process will react with any compound containing carbon-hydrogen or sulfur, reducing them by successive oxidation to odorless and harmless by-products. If airborne contaminants are outnumbered by the activated oxygen atoms, then there will be formation of residual ozone (O3), which will occur following the oxidation of normal oxygen molecules (02).

3- NEUTRALISATION PHASE: (also germicidal)  O3+UV(C) –> O2+O*: O+O –> O2


Formaldehyde CH2O + OH* –> CO2 + H2O

Ammonia NH3 + OH* –> N2 + H2O

Styrene C8H8 + OH* –> CO2 + H2O

Mercaptans H2S + OH* –> SO2+ H2O


Many buildings and facilities can be equipped with these in-duct units, like buildings near airports and helipads, buildings with adjoining warehouse (diesel), printing shops, restaurants, mechanical workshops, and crematoriums.
