Antimicrobial Duct Coating for HVAC Systems
Indoor air quality has become a leading environmental issue. Studies have shown that the air we breathe indoors is often more polluted than outdoor air. As well as, 70 or more percent of indoor air quality problems involve HVAC systems. Ductwork manufactures with AgION™ antimicrobial coated steel helps resolve these contamination issues by providing a second line of defense against destructive microbes.
Quality from Start to Finish
The demand for antimicrobial products is increasing. More and more owners and engineers are requesting it for its effectiveness in inhibiting the growth of damaging bacteria, mold and fungi.
AgION™ antimicrobial-coated steel ductwork is durable and should be incorporated into HVAC systems for hospitals, pharmaceutical facilities and food processing amenities, schools, daycare centers and nursing homes.
We are incorporating AK Coatings’ AgION™ Antimicrobial Steel into our complete line of Heating, Ventilation, and Air Conditioning ductwork. SPOT AgION™ is our name and available through our knowledgeable team.

SPOT AgION™ Antimicrobial Coated Ductwork
The AgION™ antimicrobial compound is a long-lasting, inorganic material that contains silver ions – safe and natural antimicrobial agent. The compound has two key components working together to suppress the growth of microbes: Silver Ion (the active agent) and Zeolite (stores the silver ions and releases them).
When moisture is present the Zeolite gives a controlled release of Silver Ions into the environment. This release provides continuous antimicrobial protection for the product. As the humidity increases, the environment becomes ideal for bacterial growth, more Silver Ions are released.
For most types of bacteria, the treated surface will be virtually free of microbial contamination within three to four hours. Protecting the product from degradation for the life of the coating.
Coated products must still be cleaned to ensure the surfaces will be free of destructive microbes. This serves as an added cleanliness to support regular cleaning routines between each cleaning. The coating life is a function of the application and surface wear, but could average between 10 – 30 years depending on the thickness of the coating and the wear it receives.
The coating containing the AgION™ antimicrobial compound shall withstand temperatures not to exceed 350°F for an extended period of time.
AK Coatings’ offer antimicrobial coated galvanized products up to 60 inches wide in gauges for 0.018 inches to 0.060 inches. Products are also available up to 48 inches wide in gauges from 0.060 inches to 0.075 inches. Heavier gauge coating capabilities are currently being developed.
SPOT AgION™ Antimicrobial Steel duct can be produced in rectangular, round, and flat oval as supplied by Spiral Pipe of Texas, Inc. Duct system components shall be manufactured from gauges defined in SMACNA’s Duct Construction Standards – latest edition. Coating containing the antimicrobial compound shall have a hardness of 2H minimum when tested per ASTM D3363.
SPOT AgION™ Antimicrobial Duct utilizes a coating that contains silver ions.
Application
The AgION™ antimicrobial compound is blended into a paint system and applied to AK products by continuous coil coating. The interior surface is treated with the AgION™ antimicrobial coating uniformly and applied with a minimum thickness of 0.1 mils. An untreated clear coating is applied to the exterior surface of the duct. If necessary, both surfaces of the ductwork can be treated with the coating containing the AgION™ antimicrobial compound.
Gaps in the coating wider than ¼” shall be repaired in order to maintain product performance. Repair kits are available in spray or brush applications and can be purchased through Spiral Pipe of Texas to the installing contractor.
