Description

INSULATION

The Polyfex core is wrapped in 200 gram/m2 polyester fiber insulation which is held in place with a metalized polyester jacket. The metalized jacket also gives it an extra vapour barrier.

JACKET

The metalized polyester jacket is constructed with 2 layers metalized polyester.

APPLICATION

The aluflex flexible ducts are used in ventilation, air conditioning, and air handling systems where high mechanical strength, temperature and fire resistance is required.

• Temperature range: -30° C to +100° C
• Air velocity:Up to 30m/s
  Note: At these velocities sound through the flex could be generated. Recommended
  velocity is 4m/s.
• Operating Pressure: Max 2000Pa
• Bent radius: 1.5D (1.5 times the diameter)
• Diameter range: 102mm to 559mm

• Fire Safety:Metalized polyester ducts has not been fire rated.
• Lenghts: Standard lengths are 10 meters, other lengths are available on request.
• Packaging: The Polyflex plain is shrunk down from 10m to 30cm and the Polyflex insulated is shrunk down to 100cm and then placed in a colour coded plastic bag.
