Germicidal Upper Air Sconce

    The GUA S is a wall-mounted sconce designed for upper air germicidal irradiation. These fixtures utilize low-wattage, ozone-free GUVT8 lamps that reduce airborne pathogens using 254nm UVC. The electronic ballast is specifically matched to the lamps for optimal performance and lifetime. The GUA S is constructed of durable cold rolled steel with a silver (standard), white or black powder coat finish. The polished aluminum reflector is engineered for optimal dispersion of UVC wavelength for irradiation of pathogens. A pendant mount version is also available - the GUA P. The GUA S is part of the UVFocus product line of pathogen eradicating luminaires.
    Note: UVFocus products are designed utilizing proven germicidal and antibacterial technology. UVC 254nm products work to deactivate most common viruses (as well as bacteria, molds and yeasts), and 405nm near-UV products are shown to substantially reduce bacterial presence. While these products can be considered disinfecting products, they should be used in conjunction with standard, proper disinfecting cleaning procedures to have the greatest impact for maintaining a clean environment. Successful UV disinfection requires a systems approach taking into account dose, optics and safety relevant to the specific application. Please consult with factory any questions or concerns.

  • Caution: Do not ascend into the path of irradiation emitted from this product. Make sure unit is powered off before climbing ladders, stairs, etc., or in any other situation where you are above the mounting height of the unit. At 254nm, direct UVC irradiation is not safe for humans. Avoid looking directly at the light and take necessary precautions during installation and maintenance of this product. Lamps used in this product contain mercury. Each product ships with warning labels on the fixture and safety handling guides in the cartons. Please read and heed all safety instructions before using this product.

    The AirFocus ("AF") option provides added fans to help maximize air flow, and allow a greater percentage of air and pathogens to traverse the eradication zone.

Particle Ionization

    The "AFPI" option adds an internal bipolar particle ionization unit inside your GUA S. Air is pulled into the unit via the AirFocus fans and blown across the bipolar ionization unit inside. The ions are then broadcast into the room to assist with pathogen control, odor control, and particle reduction.

  • Pathogen control: The positive and negatively charged ions emitted from the internal particle ionization unit will attach to a bacteria or virus and will kill/inactivate it by removing the hyrogen necessary to survive.
  • Odor control: The ions produced by the internal particle ionization unit break down gases with electron volt potential numbers below 12. These harmful gases are reduced to compounds or molecules already prevalent in the atmosphere, some of which are oxygen, water vapor, nitrogen and carbon dioxide. This will break down ammonia, formaldehydes, and many other odor-causing molecules.
  • Particle reduction: Bipolar ionization generates both positive and negative ions. Once produced, the ions have a lifespan of approximately 60 seconds. The particles can be comprised of asthma and allergy triggering small particles that include pollen, mold and many other organic contaminants. The ions cause some particles to become positively charged, while others become negatively charged. Because opposite charges attract, these particles become magnets and start sticking together, which is called "agglomeration." As the particles become larger, they are propelled into the filters of the HVAC system, where they are trapped due to the larger size.
