Without Mounting Holes—Drill your own holes or weld into place.

Steel—Strong for a long life, these steel flanges can be painted or coated. Unless it’s finished, steel is best for dry environments.

Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.

Lightweight Aluminum—One-third the weight of steel, aluminum ductwork is easier to handle during installation. Like galvanized steel, it resists rust in wet environments but won’t last as long.

Barometric Draft Dampers

These dampers improve furnace performance by automatically opening and closing to maintain a consistent airflow despite changing environmental conditions.

Single-Acting Damper—Single-acting dampers open inward to prevent strong drafts from pulling too much heat into the chimney vent.

Double-Acting Damper—Double-acting dampers open both inward and outward to relieve pressure caused by obstructions and downdrafts.

Spark Traps for Quick-Disconnect Duct

Reduce the risk of fire by snuffing out sparks before they get into your dust collection system. These traps slow down and rotate airflow so sparks are extinguished before exiting. They’re commonly used in systems that collect material from metal grinding and welding.

Powder-Coated Steel—The finish adds a layer of protection against corrosion and wear from moisture, heat, and abrasive dust.

Duct Clamps

Blast Gates for Quick-Disconnect Duct

Slide these gates open and closed to control airflow to sections of quick-disconnect duct. Unlike dampers, which regulate flow, blast gates turn flow on or off. They’re commonly used in dust collecting systems, either to direct suction or collect material in a specific section of duct. Secure gates to a line using quick-disconnect clamps.

304 Stainless Steel—The most corrosion-resistant metal duct we sell outperforms galvanized steel in harsh environments. It won’t rust or degrade in systems that exhaust chemical fumes or vent heat from industrial ovens and dryers.

Easy-Install Blast Gates

Add a blast gate to your system without disassembling the run. To install, cut a thin slot in the duct for the slide blade, and then mount the collar to the outside. Gates open and close to control airflow to sections of duct. They’re commonly used in dust collecting systems, either to direct suction or collect dust in a specific section. Also known as half gates.

Aluminum with 304 Stainless Steel Slide—These blast gates have a 304 stainless steel slide that holds up to moisture and mild chemicals better than galvanized steel. The aluminum body reduces stress on your duct.

Noise Reducers for Quick-Disconnect Duct


	Duct Clamps

Muffle noise from high-velocity airflow and fans, blowers, and dust collectors. These reducers are insulated to cut sound levels in your facility by 25%. Install in quick-disconnect duct systems using clamps.

Galvanized Steel—Strong and corrosion resistant, galvanized steel is the most commonly used ductwork material.
