Combi-Flex is produced from multi-layer aluminium & polyester strengthened with high tension steel spring wire, covered with a PVC layer. Combi-Flex is recommended for discharging welding fumes (where high mechanical resistance is required), low and medium pressure heating, cooling and air conditioning systems. Combi-flex is more effective against condensation than a standard non-insulated aluminium flexible air duct. To maintain indoor air quality at a certain level, preventing condensation is important. Accumulation of water on the duct surface arising from condensation leads to problems such as mould growth and corrosion, which would cause serious health problems and deformation of building materials and components. Punctures and tears could also lead to condensation and air leaks. Prevention from such deformations is achieved by adding a PVC layer which maintains more mechanical resistance than aluminium flexible air duct. Can easily be cut to length, and no special tools are required for cutting or fixing. Combi-flex is elastic and flexible. It can be easily fitted to circular, oval, or rectangular connectors.
