Dual 20" Lamp Duct UVC $395.00.
The Sapphire remains an industry standard, particularly for large installations, because of its stainless steel housings, high-output lamps, ease-of-installation, and "lamp-out" indication visible through the housing. This double-lamp unit provides maximum UV dosage on a single coil.

UVC Germicidal Fixtures increase the value of all air conditioning and air-circulating systems by:
- Maximizing system efficiency
- Prolonging blower life
- Providing healthier air to breathe
Treating air that passes through an HVAC unit with ultraviolet light will reduce, or eliminate, DNA-based airborne contaminants (bacteria, viruses, mold spores, yeast, protozoa), and provide much healthier air to breathe. UVC Germicidal Fixtures are a labor-free solution that will not harm occupants, equipment or furnishings because they produce no ozone or secondary contaminants. For more than 70 years, tens of thousands have been safely installed in hospitals, clinics, processing plants, commercial offices, manufacturing sites and other commercial facilities and multi-and single-family residences around the world.
Basics of UVC
For HVAC applications, just as with all other UVC sterilization applications, direct exposure to 254nm UVC radiation, given appropriate exposure time, will inactivate the DNA and RNA of microorganisms (such as bacteria, viruses, mold spores, yeast, and protozoa), rendering them "sterile" (unable to reproduce), which, in biological terms, results in a "dead" microorganism.
An acceptable kill rate is determined by the total amount of UVC energy a microorganism "sees." This is a "dosage." Dosage is a product of the intensity of UVC radiation (expressed in microwatts per square centimeter) and exposure time to that radiation. You can find the necessary dosage for most common mold spores in the following table. Mold spores are generally much more difficult to kill than microorganisms and viruses and, thus, require a much higher dosage of ultraviolet light. The values shown under the percentage kill are in microwatts per square centimeter of UVC energy.
