Hi-Velocity 20062030025 3in HE x 25′ R8.4 Supply Tubing Extension (1 Piece)
Hi-Velocity Flexible Duct can be installed quickly and easily, delivering the air quietly with a sound absorbing inner core. The inner core is made of a double lamination of foil laminate and clear polyester film which is interlaced with a galvanised steel wire (.041) having a 3/4 pitch.
The core is wrapped with fibreglass insulation certified GREENGUARD having a coefficient of R4.2/R8.4 and is encapsulated by a metalized vapour barrier reinforced with fibreglass string.
Our HE duct has been designed as a direct alternative for two 2 flex duct used in the Hi-Velocity System.
No changes are required to air handler selection and main plenum duct sizing.
e.g. 1 – 10 length of HE duct is the equivalent of TWO 2 -10 flex lengths.
