Product Information
Advantage of our product
Inner Duct(Core) Material
There are several materials used for flexible duct core. Generally, flexible duct is used inside buildings, do fire proof or retardant materials are mainly used. For outdoor ventilation, non-fire-retardant materials can be used. However, it would be risky and dangerous to use non-fire-retardant or proof materials for indoor purposes, for it may start fire. 2 or 4plies are standard, but to improve strength or rigidity, more than 4plies can be applied.
Basically, material will be determined according to the usages and applications of the flexible duct. The pressure drop may be influenced depending on the type of materials. The following are the main applications for each material:
·Heating & cooling Purpose : Aluminum Foil, Fiber Glass Fabric
·Outdoor Ventilation Purpose : Tarpaulin, PVC coated Tarpaulin
·Fire protection Purpose : Aluminum Foil, Aluminum
·Sound Absorption Purpose : Micro-Perforated Aluminum Foil, Spunbond
·Tunnel or Construction Site Ventilation Purpose : Special Tarpaulin
·Dispalying Application : Transparent PE film
·Hot Gas Application – Silicone Coated Fiber Glass Fabric
Copper-Coated Steel Wire
This is for making flexible duct into a round shape and keeping rigidity of the duct. This wire is metal materials, so it can be oxidized by moisture in the air. So the wire should be coated for a longer lasting life. And the wire helix distance normally connects with pressure loss. If the distance is long, an inner duct can be corrugated and cause a relatively big pressure loss. To prevent corrosion and to keep a long durability, the steel wire is coated with copper.
Adhesive
One of the most important and critical factors is adhesive, which binds inner duct materials and steel wires to make it strong. If the adhesive does not hold the core materials and the steel wires very well, this causes air leakage. Therefore, a good adhesive with strength and use of the proper method power is required.
The three ways of adhering are as follows:
·Hot Melting
The surface of a material is melted by momentary heat for binding. If the wire can be moved by the finger inside the adhered core, it would loose adhesive power under hot temperatures during the summer.
·Adhesion(Self-Hardening)
It would be difficult to melt the surface of metal materials such as aluminum or aluminum foil, so an adhesive is used in this case. The adhesive should be indurative, which never comes off once binded. Adhesive with viscosity agent is not recommended because this would break off at about 60℃ or higher.
·Clipping
This is used for silicone or spunbond, which the hot melting or adhesion method can not be applied. This is especially used for where it requires sanitary control such as hospitals.
Insulation Material
If there is a big temperature difference between the inside and outside of the duct, condensation occurs. To prevent condensation and to maintain the air temperature inside the duct, insulation is applied.
Among several insulation materials is glasswool, which is fire-proof and its lower heat conductivity widely used. This glass fiber is absolutely not an asbestos material, which is known as a cancer-inducer. Recently, a polyester insulation was used for easy work, Especially, this polyester insulation was widely used for clean rooms because of less dispersion of dust.
Vapor barrier (jacket)
This vapor barrier used for insulated flexible duct is to keep insulation fixed and prevent any moisture from penetrating inside the duct. Also, it is used for sound absorption duct to prevent any air leakage from the duct.
Generally, aluminum is the most popular material for vapor barrier. Recently, a polyester material was applied, which is better against salt.
