San-Air HVAC-R Anti-microbial Surface Sealer

SAN-AIR HVAC-R Anti-Microbial Surface Sealer Concentrate is a plant-based sealer designed to leave a long-lasting protective layer across ductwork and air handling surfaces after cleaning. Applied as a diluted mist or wipe, it inhibits mould, bacteria and biofilm from re-establishing inside the system — helping maintain clean airflow between service intervals. Features & Benefits: Broad-Spectrum Microbe Control: Kills up to 99.99% of mould, fungus, spores and bacteria on treated surfaces. Long-Lasting Protection: Forms a durable anti-microbial barrier that resists biofilm regrowth between services. Natural, Non-Harsh Ingredients: Made with SAN-AIR proprietary essential oils, purified water, silica alkaliser and natural binding agents. Non-Corrosive & Non-Toxic: Safe on ductwork, coils and HVAC components when used as directed. Economical Concentrate: Dilutes 1 part to 9 parts water — one 5L drum yields 50L of ready-to-use solution. Where to Use It: Ductwork & Air Vents: Internal duct surfaces, flexible ducting, registers, grilles and diffusers. HVAC-R Equipment: Air handlers, fan coil units, evaporator housings and plenum chambers. Commercial & Industrial Sites: Offices, hospitality venues, healthcare facilities, schools and plant rooms. Residential Systems: Ducted air conditioning, split system housings and return air paths. How to Use: Shut Down the System: Turn the HVAC unit off before beginning any application work. Clean the Surfaces: Remove dust, debris and existing microbial growth from all duct surfaces first. Dilute the Concentrate: Mix 1 part concentrate with 9 parts water (1:9 ratio). Apply Evenly: Spray through a fine mist sprayer, or wipe on with a clean cloth or sponge for full coverage. Dry and Restart: Allow surfaces to dry completely before restarting the system, and reapply as part of routine maintenance. Effectively Eliminates: Mould & Biofilm Build-Up: Stops spores and microbial films from re-establishing on treated duct surfaces. Airborne Bacteria & Fungus: Disrupts microbial survival and reproduction throughout the air path. Musty, Recirculated Odours: Helps neutralise stale smells caused by contamination inside the system.
