Title Mold contamination and air handling units
Bibliographic information July 2007, Vol.4, No.7, p.483-491. Illus. 20 ref.
Abstract An investigation was conducted on selected locations in air handling units (AHUs) to identify common mold species found on these equipments, to determine whether some locations featured mould growth sites more frequently than others, to ascertain whether the operating condition of AHUs is related to mould contamination, and to provide a basis for a microbial sampling protocol for AHUs. Samples were collected from the blower fan blades, insulation, cooling coil fins and ductwork from 25 AHUs. Results showed that Cladosporium sp. fungi were commonly found in the blower fan blades, the ductwork, and the cooling coil fins. Other organisms such as Penicillium sp., Aspergillus sp., and Paecilomyces sp. were also found on cooling coil fins and insulation. Implications of these findings are discussed.
