AC duct manufacturing in Al Wafa

We close the long seams with a tight mechanical lock as the sheet is formed, then seal every seam and every joint between sections with Foster sealant before insulating. Sections leave the workshop with matching flanges that tighten evenly when hung, because any small gap in cold duct means lost air and a point where condensation forms.

Sections arrive fabricated, insulated, sealed and numbered to the route drawing, so the fitters know where each piece goes without cutting or altering on site. What is left on site is joining the sections, fixing them to the hangers and connecting the unit and outlets, which shortens the work above the ceiling.

Yes, we fabricate plenums for both types. A cassette unit plenum is measured to match the unit's outlet frame exactly so air reaches the branch runs without leaking at the connection. A cabinet unit plenum is made to carry both the supply and return paths if the design calls for it. Both types are insulated with Kimmco or Armaflex and sealed with Foster sealant before they leave the workshop.

Yes. The workshop is equipped to fabricate large supply and return trunk runs suited to commercial, government and industrial buildings. Each section is made to the project drawings, numbered and delivered ready to hang after insulation and sealing. When engineering drawings are available, the technical team reviews them before fabrication starts to confirm that the duct dimensions fit the ceiling voids on site.

The duct carries cold air through a ceiling void that may be hot and humid. Without external insulation, water vapour condenses on the cold sheet and drips onto the false ceiling or the goods below. So each section is wrapped in Kimmco or Armaflex in our workshop and every edge and joint is sealed with Foster sealant before delivery.

Yes, workshop-made ducts are cut to exact dimensions, every seam sealed with Foster sealant and fully insulated, so there is no cold air loss and no moisture condensing on joints, unlike hand-cutting which leaves gaps and unprotected surfaces.

We make the ducts and plenums numbered according to your project drawings, and deliver them in sections that can be carried and hung on site without re-cutting or any air loss.

Full insulation of the ducts greatly reduces moisture condensing on the outer surface, but proper drainage from the collection pan and adequate ventilation control ensure humidity does not build up inside the airflow system.

We deliver the ducts numbered and ready to hang, and our team can handle installation and joining if your project requires it under a separate agreement.
