Description

The ZANDAIR PCOC™3 (Photocatalytic Oxidation Chamber) model is a powder-coated metal encased unit to be fitted into the HVAC/AHU unit or the air ducting to provide an airtight flow of the airstream through the unit. This model consists of three chambers, each with photocatalytic grids to provide additional dwelling time for maximum breakup of the molecular structure of the VOCs passing in the airstream. The ZANDAIR PCOC™3 has available spaces for an optional/removable MERV-13 (Minimum Efficiency Reporting Value) filter and a Potassium Permanganate Filter (PPF). The PPF is specially formulated to adsorb any ambient formaldehyde / aldehydes.

The ZANDAIR PCOC™3 uses Photocatalytic Oxidation (PCO) technology and converts and neutralizes Volatile Organic Compounds (VOC), odors, fumes, and toxic chemicals to benign water and carbon dioxide by-products. The process is called heterogeneous photocatalysis or photocatalytic oxidation. "In chemistry, photocatalysis is the acceleration of a photoreaction in the presence of a catalyst. In catalysed photolysis, light is absorbed by an adsorbed substrate. In photogenerated catalysis, the photocatalytic activity (PCA) depends on the ability of the catalyst to create electron–hole pairs, which generate free radicals (e.g. hydroxyl radicals: •OH) able to undergo secondary reactions. Its practical application was made possible by the discovery of water electrolysis by means of titanium dioxide."[1]
