Product Categories
Products That Fit Your Needs
Gustafson’s duct systems and air distribution devices help simplify installation and deliver air where your building needs it.
G-3® Self-Sealing Duct System
G-3 combines spiral duct with gasketed fittings that seal as they are assembled. The self-sealing connection eliminates the need for mastic at gasketed joints, helping simplify installation and adjustments.
G-0® Nongasketed Round Duct & Fittings
G-0 provides nongasketed, single-wall round duct and fittings for HVAC air distribution. A range of elbows and branch connections supports duct routing, with joints sealed during installation according to project specifications.
HV2 High Velocity Ductwork
Developed for residential high velocity systems, HV2 ductwork uses self-sealing gasketed fittings to help limit air leakage. The line supports home renovations where reducing the extent of reconstruction is a priority.
Air Distribution Devices
Gustafson’s air devices include registers that mount directly to spiral duct and rectangular taps for grille connections. Adjustable drum louvers help direct airflow in larger spaces such as theaters and shopping centers.
