PHOTO-CATALYTIC OXIDATION CHAMBER
The ZAND-AIR PCOC™3 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 and has the spaces for an optional removable MERV-13 and optional removable Potassium Permanganate Filter. 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 ZAND-AIR PCOC™3 uses PHOTO-CATALYTIC OXIDIZING (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.
The ZAND-AIR PCOC™3 model carries an additional slot for an Potassium Permanganate Filter (PPF) to absorb aldehydes remaining in the airflow. This optional PPF filter with Potassium Permanganate is specially formulated to adsorb any ambient formaldehyde / aldehydes. This PPF filter can be ordered on demand for this feature.
Using recirculating return air as part of the incoming airstream is thus helping in this cleaning process, as the return air already passed before through this photo-catalytic oxidation process.
