The Agion antimicrobial compound has been registered by the Environmental Protection Agency as an antimicrobial agent which can resist the growth of bacteria, molds and fungi. Additionally, the Agion antimicrobial coating offers stain resistance, as well as a smoother surface, resulting in antimicrobial-coated steel that is easier to clean and maintain. Agion can be applied to components throughout the entire heating, ventilation and air conditioning (HVAC) system, including air handlers, ductwork, and diffusers. These coatings can also be used on many other carbon and stainless steel products, including commercial refrigeration systems, appliances, and building components. For manufactured HVAC components, coatings are available through authorized shop coaters. Coils of antimicrobial-coated carbon and stainless steel may be purchased directly from AK Coatings, or the coatings may be applied by an authorized coil coater to carbon steel purchased from any manufacturer.
