EHG duct systems are manufactured to strict published tolerances. EHG's G-3® triple-lipped
self-sealing gasketed connection meets SMACNA Leakage Class 3 performance and is available in diameters up to 60".
EHG systems are offered in both single and double wall construction.

Not all projects are created the same. We understand this and employ an educated staff of trained welders
who can build ductwork to suit your project's special demands. From fully welded and manifolded pieces to
dust collection systems, EHG provides only the finest HVAC duct systems.
