General Flexible Duct is the best type of flexible duct due to its elastomeric insulation and durable PVC coating.

This duct has the highest thermal coefficient reduction and no energy loss according to the National Regulations, Section 19, and is the best type of flexible duct in terms of insulation.

This duct has an outer layer of 140 micron black PVC, which is highly resistant to tearing and is the most resistant pipe in this respect.

The inner layer, like the rest of the ducts, is aluminum laminated with polyester, which alone is very resistant to heat and prevents the accumulation of bacteria and fungi.

The insulation of this duct is a layer of elastomeric insulation with a thickness of 3 mm and a strip width of 5 cm.

۱۸۰ micron layer thickness includes:

Inner layer made of aluminum tape with polyester

Middle layer made of 3 mm thick elastomeric insulation

Outer layer made of PVC

High carbon wire diameter: 1 to 1.7 mm (depending on the size produced)

Maximum pressure tolerance range: 4200pa

Air speed: Maximum 30 m/s

Temperature tolerance range -25 to +120 degrees Celsius (indirectly)

Packaging size: 6 meter packages are available (produced in the desired size depending on the need)
