Quick Assembly Ductwork Instructions

At Norduct Ltd we are aware that quick turnaround is important. We also understand that ductwork should allow for quick installation and be cost effective. This is why we manufacture the quick assembly clip system, as it is so easy to install. Each quick assembly ductwork system eliminates the need for complicated rivets and screws as it functions with a quick release clip.

Ease of assembly and re-assembly makes this an ideal system. For example the QA rolled end clip duct takes 50% less time to be installed than a spiral duct.

Some of the benefits of a quick assembly clip system include:

  • Easy to install
  • No rivets, screws or weld required
  • Quick release clip with seal
  • Smooth internal finish
  • Easily adapted to existing systems
  • Available in galvanised and stainless steel

Instructions For Installing The Quick Assembly Duct Systems

To create a 90- degree angle branch, connect a 30-degree branch and a 60-degree elbow piece together. Layout the branch and elbow assemblies on the floor as outlined in the diagram below:

Connect the branches to ducting sections of the correct length and diameter. Adjustment to length on duct sections is achieved by using Norduct slip joint assembly instructions.

Carefully raise main or sub-main to required centre line height above floor using preferred ASM hanging material.

Extend branch arms to machines using correct length and diameter duct. Adjustment to length of duct sections is achieved by using Norduct slip joint assembly instructions. Fit another 90 degrees elbow on the end of each horizontal run.

Install vertical risers from machines to horizontal runs using your preferred method of connection.

Connect main or sub-main to filter, fan or desired machinery with required standard or custom fitting manufactured by Norduct, or continue with next section of system.

Installing A Slip Joint Into A Ducting System

Requirements for using an adjustable slip are a duct length less than the standard 1250mm section of duct.

Cut non-standard length from standard 1250mm section of duct.

 

Be sure that the cut section of the duct is placed into the line with the direction of airflow.

Adjust the assembly to the proper length required for the space to be filled.

Finish connection using the adjustable slip assembly.

 

Temporarily place the Branch Plate on the main duct in the required position, and while holding in place, mark the interior of the branch on the duct line where it is to be cut.

Take down branch plate and drill a starter hole in the main duct along the line traced from the branch. Then using metal snips or a jigsaw, cut out metal piece that has been traced out. File or grind any sharp edges to ensure efficient flow.

Now use an industrial strength silicone sealant to seal between branch plate and main duct. Use small sheet metal screws or pop rivets to secure branch plate to the main trunk.

Wash down all components with an industrial degreaser, ensuring that no oils or residues are left behind. Apply an epoxy primer in a light coating. For final coat, apply an acrylic water base paint.
