Confined Space Ventilation Ducting

Ventilation ducts are designed for use with confined space fans for providing fresh air supply and ventilating hazardous gases & fumes from basements, manholes and chemical processing plants. Raptor Supplies offers a wide array of Allegro, Ecko, Americ, Ramfan and Air Systems International blower exhaust ducts featuring a flexible design for ensuring quick installation in tough-to-reach spaces. Allegro ventilation ducts feature a statically conductive design for discharging the static build-up and preventing accidental sparks in hazardous locations, and a neoprene coating for withstanding temperatures up to 250 degrees F. Ventilation ducts from Air Systems International are made of polyethylene / vinyl for maintaining structural rigidity and also facilitate ease-of-storage & maximum job-site portability. Choose from a wide range of these ducts available in diameters ranging from 8 to 26 inches.

Working Mechanism

  • HVAC ducting is installed in voids above a suspended ceiling.
  • The ducting is responsible for supplying and extracting air from occupied spaces below.
  • Diffuser grilles are used to distribute the air into the room or extract air from the room.
  • Fans or air handling units are used to draw or blow air through the ducts.
  • The airflow is controlled and directed to achieve proper heating, ventilation, and air conditioning in the building.

Frequently Asked Questions

How long are these ducting units?

They are available in sizes ranging from 6 to 825 ft.

When does confined space ventilation matter?

Ventilation in confined spaces is always important. According to OSHA's confined space standard (1910.146 Permit Required Confined Spaces), no workers are permitted to enter a space if a gas detector detects an atmospheric hazard. Employees are also not permitted to enter a space until forced air ventilation has been used to eliminate atmospheric hazards and this ventilation must continue until all employees have left the workspace.

Are these ducts ideal for use in extreme environmental conditions?

Americ ventilation ducts are made of PVC, vinyl coated polyester and can withstand UV radiation, humidity and extreme environmental conditions. They can also be easily connected to ventilator fans or blower lips for negative or positive airflow.

How do I clean maintain confined space ventilation ducting?

  • Perform visual inspections regularly to check for damage, wear, or blockages.
  • Remove any accumulated debris, dust, or obstructions inside the ducting.
  • Mix water with a mild ducting cleaner or detergent for a suitable cleaning solution.
  • Use a soft brush or cloth to apply the cleaning solution to the interior surface of the ducting.
  • Gently scrub the interior surface to remove dirt, grease or residues without causing damage.
  • Thoroughly rinse the ducting with clean water to remove the cleaning solution and debris.
  • Allow the ducting to air dry completely to prevent moisture buildup.
  • Check seals, joints, and connections for wear or damage, and replace them as needed.
  • Store the cleaned and dried ducting in a clean, dry area away from potential damage or contamination.

How to install confined space ventilation ducting?

  • Prepare the work area by clearing obstacles and debris.
  • Measure the length and width of the installation area and plan the ducting route.
  • Gather all the necessary equipment for installation.
  • Connect the sections of ducting using appropriate connectors and clamps.
  • Position the ducting along the planned route and secure it with straps or hangers.
  • Install the inlet and outlet components, such as grilles or diffusers, ensuring proper alignment.
  • Seal the joints and connections using duct tape or other sealing methods.
  • Test the system for proper airflow, functionality, and potential leaks or obstructions.

What are the safety precautions to consider while using confined space ventilation ducts?

It is important to ensure that the ducting is properly secured and does not obstruct pathways or create trip hazards. Regular inspection and maintenance should be conducted to identify any damage or wear and replace any worn-out components.
