Quality Air in General Commercial Buildings

The purity of ambient air is a process that many industries throughout the world continue to focus on improving.  Much of the research and development is centered on removing both dry and liquid particles.  In the industrial sector continued improvements have been made to comply with EPA regulations, and reduce particulates to improve general working conditions. Quality air is our specialty; we clean air down to the last molecule.

The ZAND-AIR PCOC™3 uses the recognized technology that destroys harmful molecules.  That technology is known as Photocatalytic Oxidation. (PCO).  The ZAND-AIR PCOC™3 is the key to quality air in your commercial environment.

Photocatalytic Oxidation is the process combining UVC irradiation (257.3 nm) with a substance (catalyst) titanium dioxide (TiO2) which results in a reaction that changes malignant microbes into water, carbon dioxide and detritus.

The air purification process of using photocatalytic oxidation often works by using an existing air system that pulls air through an air conditioning unit (HVAC) which passes through the professionally installed ultraviolet light/ titanium dioxide chambers. As the malignant microbe filled ambient air circulates through these chambers the microbes are “attacked” by free hydroxyl radicals and super-oxide ions, (created by UV light and titanium dioxide) breaking their cellular structure apart and destroying both the intracellular mass and DNA/HNA chromosomes. The result is harmless water molecules, carbon dioxide and detritus. (See diagram above.)

Portable units use fans to draw the air through the photocatalytic oxidation chamber. These units are very effective in smaller rooms.

Recognizing a need for an air filtration/purification system that is efficient, quiet, and affordable as well as the ability to attack the molecular structure of hydrocarbon pollutants, volatile organic compounds, and chemically active compounds is essential if you want to have a safe ambient air environment for employees, clients, visitors and yourself.

Photocatalytic oxidation destroys microbes, volatile organic compounds (VOCs), and chemically active compounds (CACs).

Photocatalytic Oxidation (PCO) is a very powerful air purification technology and has the ability to destroy particles as small as 0.001 microns (nanometer). In comparison, HEPA filters can filter particles as small as 0.3 microns. Several studies have been done at Universities such as Penn State and Colorado. A book titled Aero Biological Engineering Handbook by Wladyslaw Jan Kowalski supports these findings as well.
