Ideal for all air conditioning/ventilation systems, such as hospital, hotel, commercial
building as well as and industrial and residential application
Advantage:
1. Available bare and pre-insulated type with glasswool insulation
2.Tear and puncture resistant construction
3.Spring steel wire helix assures dimensional stability and more efficient air distribution
4.Highly resistant to corrosion and micro organisms
5.High degree of flexibility, which allows it to be easily connected to any desired
position, especially where pre-cast ducts would be difficult and costly to be
installed
6.Quick and economical means of correcting misalignment between systems components
7.Low friction loss and no air leakage if it's installed in the right way
8.No toxic gas emitted when exposed to fire or high temperature
9.Compressed ducts reduce freight and storage cost

Flexible air duct trunk lines should not be limited in length. It is recommended as a guide that flexible air duct branch takeoffs (run-outs), flexible air ducts direct to boots from the plenum and flexible ducts in radial duct systems be limited in length to 25 feet (7620 mm)..
The routing and length of flexible duct, the numbers of degrees of each bend and the amount of sag allowed between support joints will have serious effects on system performance due to the increased resistance each introduces. Use the minimum length of flexible duct to make connections. Do not install excess lengths of ducts to allow for possible future relocations of air terminal devices.
Flexible duct is for indoor use only; do not install product where exposure to direct sunlight can occur. Prolonged exposure to sunlight may cause deterioration of vapor barrier. The inner core may degrade if the duct is positioned near a bio-treatment lamp (UV emitter) installed within the HVAC system.
Flexible air ducts, both metallic and nonmetallic, should be listed and labeled as Class 0 or Class 1 flexible air ducts.
