In the past limited access to already installed air duct systems and the fact that small and individual leakages are difficult to address efficiently, the sealing of those systems has been extremely difficult. Air master 32-17 Acrylic Duct Sealant its an economical high performance, water based duct sealant designed for use in high, medium and low velocity duct system. Air master 32-17 provides excellent strength, Flexibility and resistance to heat and cold, forming a seal against air leakage. It can be very difficult to pinpoint areas of leakage, usually there are many points of small leakage which contribute to a large leakage total.

Ductwork flanged connections, slip joints, seams and fixings can all leak, making it almost impossible to manually find and seal all leakage points on an installed system.The formulation is acrylic polymer based, plasto-elastic, solvent free HVAC ducting sealant for all types of metal ducts. During duct sealing works there is a chance that smoke alarms may be activated by sealing aerosols, smoke alarms will need to be deactivated and bagged to prevent unnecessary alarms. Comfort issues can be linked to poor temperature control from inefficient HVAC, these systems can have their efficiencies boosted by improved airtightness.

SmartSeal® software gives live data throughout the Aeroseal sealing process, this monitors ductwork pressure and the reduction in ductwork leakage. Air duct manufacturers can prove that they meet the tightness requirements of DIN EN 1507 or DIN EN 12237 through their operational quality assurance and through the use of high-quality manufacturing products in production, no longer have to deal with defects caused by the installation process. Once applied the Aeroseal sealant is able to withstand 2000Pa of pressure and has an estimated lifetime of over 30 years (provided ductwork is not dismantled or cleaned with oxidising chemicals).Water Based Duct Sealant for the permanent sealing of low movement assembly joints in low, medium and high pressure ductwork installations to prevent loss of air pressure. System leakage is reduced on average by over 90%, allowing systems to meet design specification, and can be upgraded to higher classification. FiloSeal+HD is an engineered solution that provides a strong support system using the hexagonal tubes which builds up like a honeycomb structure. These entries such as open cable ducts entering substations or buildings should be sealed with or without cables installed to prevent ingress of water and gas – a common reference point in the UK is Engineering Recommendation ENA-ER G17/3 Leakage Of Flammable Gases.
