Flexible Duct Uninsulated

Description

ROCKAL Standard are fully flexible, light weight, uninsulated, laminated ducts suitable for low- and high-pressure systems. The ducts consist of several layers of aluminum and polyester laminates encapsulating a high tensile steel wire helix. Rockal flexible ducts are easily installed over either round or oval connections. At high temperature, or in case of fire, no toxic or gas emission.The ducts are manufactured according to the international standard EN 13180.

Applications:

Rockal Flexible ducts are used in heating, ventilation and air conditioning (HVAC) to deliver and remove air. Air conditioning Factory equipment Vehicle construction Bathroom Confined space Tumbler dryer Range hood Water heater Fanner

Construction and Dimensions

Construction: ROCKAL flexible ducts constructed out of a “sandwich construction” laminates. This means the different layers of aluminum and polyester are overlapping each other completely and encapsulates a high tensile steel wire. The multiple laminates are adhered with fire retardant thermosetting adhesive. Temperature Range: -30 °C to + 140 °C
Air Velocity: Max. 30 m/s (5900 ft/min)
StandardColor: Aluminum
Types:
⦁ Single layer
⦁ Double layer
⦁ Multi layer
⦁ Metalized
Thickness Total thickness of layers in rendezvous area (without wire) is about 70 μm Internal Diameter: All standard diameters ranging from 102mm to 508mm (4 – 20 inch).
Fire Class: Please see schedule on page 274.
Wire Spacing: 4 - 6" : 3.0 cm.
8 - 10" : 3.5 cm.
12 - 20" : 4.5 cm.
Wire:
⦁ thickness of wire are used: 1mm, from dia. 102mm - 178mm 1.2mm, from dia. 203mm - 315mm 1.2mm, from dia. 356mm - 508mm
Chemical Resistance:
⦁ Good resistance to many solvents
⦁ Moderate resistance to acid & base
