National Semiconductor, Arlington, Texas

Sheet Metal Contractor: Construction Mechanical Systems Inc., Grapevine, Texas

The system required the fabrication and installation of fiber glass reinforced plastic duct as well as galvanized and stainless steel duct. Structural steel supports were installed at the roof.

The make-up air unit feeds air back into the system.
The installation of two scrubbers and associated duct as well as a make-up air unit and its associated duct was a challenge that required the crew of Construction Mechanical Systems to complete the installation without production interference.

The scrubber fan and stack is one of 13 that services the Arlington facility. The two scrubbers along with the respective fans, stacks and manifold were installed at National Semiconductor without creating an interference in production.
