A spiral seam gives this duct greater strength and rigidity than standard duct.

Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes.

Weld flanges to equipment to start a run of duct.

Use in dust collection systems. The slide pushes through the top of the gate to clear debris.

More convenient than other blast gates, these automatic gates open and close in sync with dust collectors, fume exhausters, and other machines.

In the event of a fire, these dampers automatically stop airflow through duct.

Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.
