A mixing manifold is an interior part installed under the floor in the aft cabin. It's purpose is to mix fresh air from the air conditioning packs with recirculated, filtered air from the cabin. Damage occurs in-service due to moisture around the baffles that causes delamination of the inner skin with the core. Comtek has developed a repair solution for this issue.
To develop the repair, Comtek’s engineering team first needed to identify the material information of the original duct and then produce a design for repair that was both economical and fast. A series of qualification procedures were required, including flammability testing and pressure testing to ensure the airworthiness of the Comtek solution.
To our knowledge, Comtek’s delamination repair is the only known repair available on the market today for this part.
