PCO Hydroxyl Generator with 4 Optics, Treats Up to 3,000 sq ft

BoiE Hydra Hydroxyl GeneratorsThe BoiE Hydra QUAD is a 4-Optic PhotoCatalytic (PCO) hydroxyl generator with a powerful fan and is safe for continuous operation in occupied buildings to improve indoor air quality or to restore air quality following events such as floods or fires. The Hydra QUAD uses harmless (UV) blacklight to generate hydroxyls that eliminate odors, break down bacterial spores and pathogens, and leave nothing but fresh, clean air.

The Hydra QUAD uses PCO technology to attack and kill bacteria and viruses including corona-type viruses but is completely safe to operate continuously. A 2020 study suggests that COVID-19 can circulate in the air for up to three hours.¹ UV light alone will not destroy viruses circulating in the air; HEPA filtration cannot trap something as small as a virus, but PCO technology has been proven to kill viruses on contact.² Note that while no air purification system, can universally prevent coronavirus (including COVID-19) infections, it is critical to take what steps you can and to follow government hygiene guidelines.

EPA-registered EstablishmentThe compact, rugged Hydra QUAD is equipped with a replaceable 2-layer filter that reduces odors and removes larger contaminants. Next, the air passes through a UV light-activated catalyst that safely generates hydroxyls that neutralize remaining contaminants. The resulting byproducts are harmless carbon dioxide and water, leaving nothing but fresh, clean air. The Hydra QUAD's safe operation make it a great choice to leave overnight at occupied job sites or in homes and businesses.

How It Works:
Hydroxyls are highly-reactive (radical) molecules formed naturally when UV light from the sun splits apart water molecules in the air. The resulting hydroxyl radicals instantly oxidize pollutants nearby. Hydroxyls are nature's primary method of cleaning contaminants from the atmosphere using only sunlight and water vapor. Artificially-generated hydroxyls perform the same cleansing function on indoor air and cause no harm to people, pets, plants or materials.

Odors from flooding, mold spores, cigarette smoke, fire damage, sewage spills, off gassing, body odor and decomposition are all safely broken down by a hydroxyl generator until all that remains is carbon dioxide and water

PCO hydroxyl generation, originally developed by the National Aeronautics and Space Administration (NASA) to purify air onboard a space station, is ozone-free and safe to use indoors for continuous operation. Photocatalytic Oxidation is FDA-approved for use in Class II medical devices such as air purifiers, N95 respirators and infusion pumps. The Hydra QUAD has a 4-optic 368-nm UV-A (black light) hydroxyl reactor that is safe to view and causes no harm to occupants, pets, plants or possessions. The design uses space-saving U-shaped optics (ca. 5 linear ft.) to pack the most power possible within a compact unit.

The Hydra QUAD has a powerful 500 CFM (max) axial fan that draws air through its nano-catalyst reactor. The IPX7 certified enclosure is designed for the harshest environments on the planet and can be opened for service and locked for safety. Includes a straight-blade power inlet that accepts standard extension cords for convenience, and a GFCI outlet to daisy-chain units or connect accessories such as BoiE's Ultrasonic Hydroxyl Accelerator.

The Hydra QUAD can be left running continuously in occupied areas for as long as it takes to remove odors and break down contaminants. The unit has the latest PCO technology including safe-to-view TiO2-coated UVA lamps rated for 5,000-hours. BoiE's unique 360-surround permanent, nano-anatase TiO2 reactor grid produces the highest levels of hydroxyls possible without restricting airflow.

Hydroxyl generators work best when humid air enters the machine. When conditions are too dry, the Hydra QUAD can be used with BoiE's Ultrasonic Hydroxyl Accelerator to increase the moisture level of the air that is drawn into the machine.

Bottom Line:
The Hydra QUAD is great for cleaning occupied spaces when the unit can be run for longer periods of time, with or without occupants or workers present. Like all hydroxyl generators, the Hydra QUAD won't damage plants or sensitive materials. At 500 CFM, the unit strikes a good balance between air changes per hour (ACH) and fan noise. It is great to run during and after a mold remediation project to kill mold spores and to help pass mold clearance testing. Adding BoiE's optional Ultrasonic Hydroxyl Accelerator accessory can turbocharge the air intake with moisture to maximize hydroxyl production in dry conditions.

Like all BoiE products, the Hydra QUAD was designed by professionals for professionals to exceed, outlast and outperform the competition!
