Our Ductwork Supply Range

Commercial HVAC systems require more than ductwork alone, accessories and safety components help keep systems efficient, serviceable, and code-compliant. Below are examples of commercial HVAC products we supply to support ductwork projects and mechanical installs.

 

Exhaust & Booster Fans

FG Series Inline Fans

FG Series Inline Fans

  • Inline fans circulate air through the ductwork to ensure commercial buildings are well-ventilated. Our FG Series Inline Fans provide ample power to run commercial HVAC systems efficiently.

Duct Sealant

Hardcast Duct Sealer #321 UL 181B-M

Duct-Seal 321

Hardcast Flex Grip #550 UL 181B-M

Flex-Grip 550

Foil-Grip 1042

Foil-Grip 1042

2" Brushes

2" Brushes

  • Duct sealing involves insulating and sealing the metal ducts within walls throughout commercial buildings to create a reliable and efficient HVAC system. Our Duct-Seal 321, Flexi-Grip 550 and Foil-Grip 1042 duct sealants are made with nonhardening, nontoxic materials for secure sealing, ensuring air can't escape. The right sealant helps improve the air quality in commercial structures and extends the HVAC system's longevity, making it a worthwhile investment.

Radiation Fire Dampers

  • Fire dampers help prevent fires from spreading throughout buildings and minimize potential property damage. We supply various fire dampers to meet several commercial application needs. Choose our Curtain Type “A”, square ceiling or round ceiling radiation fire dampers for increased fire protection.

Louvers

Louvers 4" Drainable Blade Extruded Aluminum

Extruded Aluminum

  • Louvers' vertical or horizontal slats aid airflow and block unwanted elements, such as dust and water, from entering the system. They also help conceal the ductwork for a clean, neat appearance. Our 4-inch drainable blade extruded aluminum louvers do the job correctly.

Backdraft Dampers

Backdraft Damper Aluminum Backdraft Damper

Aluminum Backdraft Damper

  • These dampers allow sufficient airflow in a single direction and prevent backflow. They effectively mitigate humidity in commercial building spaces and are vital in operations where the presence of moisture could have a detrimental impact. Our aluminum backdraft damper helps air from becoming stale, removes musty odors and prevents mold from forming.

Air Control Dampers

Control Damper Galvanized Steel, Low Leakage AC10 Parallel Blade AC20 Opposed Blade

Control Damper
Galvanized Steel
Low Leakage

  • These provide more control over the opening and closing of blades that direct airflow within the system and can be used to help heat or cool commercial buildings year-round. They maintain optimal warmth in winter by closing off ductwork openings that let cold air enter and vice versa. Our galvanized steel low-leakage control air damper is ideal for commercial settings due to its material construction and low-leakage feature.

Access Doors

Cam Latch Access Door

Cam Latch Access Door

Hinged Access Door

Hinged Access Door

  • These are for uninterrupted maintenance access to critical areas within the system. We supply cam latch and hinged access doors to provide a quick way to enter ductwork during emergencies and other instances requiring swift ingress.

Smoke Detectors

Duct Smoke Detector

Duct Smoke Detector

  • These devices ensure smoke and signs of combustion in the air ducts can be detected at various sections of the ductwork. They prevent smoke recirculation by stopping fans and dampers when smoke is detected, making them highly effective in preventing fires from flaring in the ductwork. Consider our duct smoke detector for various commercial projects to give your customers peace of mind.
