Airestec’s Bioactive Microorganism Duct Treatment (BMDT) is specifically researched, developed and made in Malaysia (Buatan Malaysia) as an advanced solution to enhance Indoor Air Quality (IAQ) by suppressing microbial growth and biofilm formation within air ducts. It is formulated to inhibit bacteria, fungi and mould, thereby helping prevent the deterioration of air quality that can adversely affect occupants’ health, comfort and productivity.
Ducting is a crucial part of the overall HVAC system, channeling conditioned air into occupied spaces. This is especially important in critical environments such as hospitals, food-preparation and manufacturing areas, pharmaceutical plants, educational institutions, government facilities, commercial buildings and residential properties where IAQ must be maintained at optimal levels. BMDT’s non-corrosive formulation protects internal duct surfaces while helping preserve airflow, extend duct lifespan and reduce microbial and biofilm accumulation.
Applied using a hurricane or tornado misting system, BMDT provides thorough and uniform coverage of internal duct surfaces for effective, long-lasting treatment. By preserving duct cleanliness, it supports better airflow, HVAC energy efficiency and a healthier indoor environment, making it a valuable locally developed solution for facility managers and HVAC professionals.
In addition to supplying BMDT, Airestec offers optional SOP training, application planning and product application audits for government agencies, facility teams and appointed ducting contractors. These services help ensure that BMDT is applied in accordance with Airestec’s standards, thereby supporting the intended results. Guidance covers duct assessment, access and coverage planning, suitable misting methods and completion checks. BMDT may be procured as a stand-alone duct treatment or incorporated into a wider HVAC and IAQ programme, with technical support available as required.
