Angle Rings/Flanges

Angle ring flanges, commonly known as angle rings, join ductwork together. Standard rings come punched with holes. Flange angle rings are available in Carbon Steel (Black), Galvanized Steel, and Stainless Steel.

Automatic Gates (AC Voltage)

Automatic Gates, also known as Blast Gates or Slide Gates, use solenoids (12/24V AC/DC, 120/220V) to control pneumatic cylinders. Operates at 90 PSI, available in 3"-24" diameters.

Automatic Gates (DC Voltage)

Automatic Gates, also known as Blast Gates or Slide Gates, use solenoids (12/24V AC/DC, 120/220V) to control pneumatic cylinders. Requires 90 PSI. Available in 3"-24" diameters.

Automatic Butterfly Valve With Half Moon Stops -AC Voltage

Ductwork Butterfly (Gate) Valves adjust airflow with a solenoid-controlled pneumatic cylinder. Operates at 80 PSI and supports 12/24V AC, or 110/220V signals. Durable 3/16" disk ensures long life.

Automatic Butterfly Valve With Half Moon Stops -DC Voltage

Ductwork Butterfly (Gate) Valves adjust airflow with a solenoid-controlled pneumatic cylinder. Operates at 90 PSI and supports 12/24V DC, or 110/220V signals. Durable 3/16" disk ensures long life.

Cable Hangers

Trapeze-style cable hangers, or Gripple hangers, quickly suspend duct in a hammock-like setup. Ideal for supplemental support. One hanger per 10ft of duct.

Bell Mouths

Bellmouth adapters, or Mini Hoods, are short and straight ductwork that function as mini-hoods. The flared ends improve airflow dynamics, maximizing particulate capture.

Flap Exhaust Valves (Flap Stacks)

Flap Exhaust Valves (butterfly or gate), or Winged Stacks, open with airflow and close when idle, minimizing resistance and protecting ducts from rain. Available in 4"-32" diameters.

Floor Sweeps

Floor Sweeps remove debris from the shop floor where clean-up is needed. Simply open the double-hinged door and sweep away your shop debris. When done, the dust collection system vacuum holds the door tightly closed to prevent system pressure loss.

Hat Style Saddle Duct Hangers

The perfect blend of easy installation and stability, our hat style saddle hangers feature half-round sections of support duct to secure the main duct while a single-threaded rod (not included) offers fast-but-strong support.

Horizontal Oil Mist Accumulator

The Oil Mist Accumulator prevents leaks, extends mist collector filter life, and redirects excess coolant back to the machine.

Jet Caps

Jet Caps combine the best features of an old-style rain cap and the no-loss stack to offer maximum protection from water entering the stack with minimum static pressure.

Manual Air Tight Blast Gate

This airtight frame gate utilizes a fully welded body to stop leaks in your work environment. They are recommended for high-moisture systems, oil mist systems, and laboratories where a standard cut-off may leak.

Automatic Diverter Valve

Automatic Diverter Valves redirect airflow between two paths with solenoid-controlled pneumatic cylinders (12/24V AC/DC or 110/220V, 80 PSI). Heavy-duty, easy-to-clean, ideal for plastic, paper, or woodworking.

Manual Butterfly Valve

The Butterfly Damper, Butterfly Gate, or Butterfly Valve, controls airflow with a pivoting disk for precise adjustment. Locking quadrant ensures position.

Rain Caps

Prevent the intrusion of rain into the exhaust of your ductwork system with a rain cap. Our rain caps will stop the negative effects of water on your system. Water can contribute to the corrosion of components, especially fan and electrical elements. Learn more here!

Saddle Duct Hangers

Saddle hangers, most commonly known as duct supports, are the most secure ductwork hangers availabl

Vibration Dampener

Vibration dampeners reduce vibration transfer in duct systems, protecting machinery and minimizing noise. Features EDPM membrane and gauges for any application.

Vertical Oil Mist Accumulator

The Vertical Oil Mist Accumulator efficiently captures and drains excess coolant, preventing leaks, improving safety, and extending filter life for vertical duct systems.

Thermoplastic Flex Hose

Molecularly bonded high-temperature thermo-plastic rubber. SF-TPR provides outstanding performance and flex fatigue resistance. Smooth interior design allows for superior flow and maximum efficiency. Extremely flexible with excellent shape retention.

Silencers

Air Duct Noise Silencers reduce turbulence noise in ductwork, improving workplace comfort and minimizing disturbances. Also known as duct mufflers or sound attenuators.

Oil Mist Curbs

Oil Mist Curbs prevent leaks at flex hose connections by capturing coolant at the source. Fully welded curbs with weep holes funnel coolant back into the system, ensuring a cleaner, safer workspace.

Rolled Lip Duct Replacement Clamp

Durable stainless steel clamps with integrated seal (available with O-ring) for rolled-lip dust collection duct systems. Compatible with standard duct systems.

No Loss StackHead

No-Loss Stackheads reduce fan resistance, save energy, and protect exhaust fans from rain. Designed for efficient drainage, they ensure optimal airflow and durability.
