GeneralAire PCO2450 HYBRID 18" UVC Germicidal Light

GeneralAire PCO2450 HYBRID 18" UVC Germicidal Light
Price: $345.56

Improve the Air You Breathe

 One of the most powerful residential UVC light created UNMATCHED The air we breathe in our homes can be up to 100 times more polluted than outdoor air, according to the Environmental Protection Agency. So let GeneralAire provide you with healthier indoor air and “Let the Sunshine In!” with GeneralAire UVC Air Purifiers. GeneralAire’s Ultraviolet (UV) light technology enables you to have whole-house air treatment energy, like the sun, to improve your homes indoor air quality. Battle microorganisms with highly intensive ultraviolet “C” (UVC) germicidal irradiation. This air treatment is designed to be more effective at significantly reducing unwanted bioaerosols (germs) in your home. Forget about the rest, and decide on the best indoor air quality air purification system. You can count on GeneralAire ultraviolet air treatment products to out last and out perform the other brands. Let the Sunshine In! The sun that brings us daylight everyday also delivers UVC energy that protects us from germs, bacteria, viruses, and other destructive bioaerosols outdoors. Installed on your HVAC distribution system, the PCO2450 boast an intensely effective 18 inch 50 watt germicidal lamp (LT-50). The 50 watt lamp radiates a high output of germ killing ultraviolet light in your ductwork, imitating the air purifying intensity of the sun that treats your indoor air. The germicidal bandwidth C (UVC) measuring 200 to 280 nanometers is effective at killing germs and bacteria in your home and will significantly reduce the levels of harmful bioaerosols (viruses, fungi, mold, and allergens).

How are Bioaerosols Eliminated? The high output UVC energy will break down the electron bonds of an organic molecule. This intense energy will penetrate an airborne microorganism causing cellular and genetic damage that either destroys the microorganism or renders it harmless by robbing it with the ability to reproduce.

 

 Hybrid PCO2450 UV Air Purifier

 

The Hybrid PCO2450 (Photocatalytic Oxidation) Air Purifier features the patented VectorFlo® semiconductor designed to deliver a high performance kill rate unmatched by other ultraviolet air treatment brands. The VectorFlo® creates a low pressure area around the high output 50 watt UVC lamp establishing a venturi effect. The venturi significantly increases the time exposure of airborne microorganisms in a bath of sterilizing germicidal ultraviolet light. The treated unrestricted air (.02 inches W.C.) is then accelerated beyond the VectorFlo® semiconductor and introduced into the main airflow for maximum purification. The patented semi-conductor’s exclusive process incorporates 24 SQFT equivalent surface area of honey combed aluminum cells. The cells are electro-statically coated and permanently bonded at high temperatures with nanosized crystallites of titanium dioxide TiO2 in an anatase form. This specific process is proven to be one of most effective photocatalyst. A photochemical reaction occurs when UVC light is absorbed by the TiO2 semiconductor. An advanced oxidation conversion process occurs where the H2O molecule in the airflow is split to create hydroxyl radicals (OH) and super oxide anions (O2) known to beamong the most powerful oxidizing radicals. This Photocatalytic process aggressively deconstructs gaseous contaminants and deodorizes your indoor air safely.

Penn State On Photocatalytic Oxidation

Titanium dioxide (TiO2) is a semiconductor photocatalyst with a band gap energy of 3.2 eV. When this material is irradiated with photons of less than 385 nm, the band gap energy is exceeded and an electron is promoted from the valence band to the conduction band. The resultant electron-hole pair has a lifetime in the space-charge region that enables its participation in chemical reactions. The most widely postulated reactions are shown here.

O2 + e- _________> O2-

Hydroxyl radicals and super-oxide ions are highly reactive species that will oxidize volatile organic compounds (VOCs) adsorbed on the catalyst surface. They will also kill and decompose adsorbed bioaerosols. The process is referred to as heterogeneous photocatalysis or, more specifically, photocatalytic oxidation (PCO).

Several attributes of PCO make it a strong candidate for indoor air quality (IAQ) applications. Pollutants, particularly VOCs, are preferentially adsorbed on the surface and oxidized to (primarily) carbon dioxide (CO2). Thus, rather than simply changing the phase and concentrating the contaminant, the absolute toxicity of the treated air stream is reduced, allowing the photocatalytic reactor to operate as a self-cleaning filter relative to organic material on the catalyst surface.

Photocatalytic reactors may be integrated into new and existing heating, ventilation, and air conditioning (HVAC) systems due to their modular design, room temperature operation, and negligible pressure drop. PCO reactors also feature low power consumption, potentially long service life, and low maintenance requirements. These attributes contribute to the potential of PCO technology to be an effective process for removing and destroying low level pollutants in indoor air, including bacteria, viruses and fungi.

Technical issues that must be confronted before PCO reactors can be used in this application include the formation of products of incomplete oxidation, reaction rate inhibition due to humidity, mass transport issues associated with high-flow rate systems, catalyst deactivation and inorganic contamination (dust and soil).
