Inflatable Ventilation Control (IVC)
VENTILATION CONTROL SYSTEMS FOR MINING
Inflatable ventilation control for underground mining
PolyFusion designs and manufactures Inflatable Ventilation Controls (IVCs) for underground mine ventilation control applications where airflow needs to be controlled, redirected or isolated.
Depending on site terminology, flexible controls of this type may also be described as inflatable stoppings, mine ventilation barriers or inflatable ventilation barriers. An IVC provides a rapidly deployed alternative to constructing a conventional rigid stopping where the application suits an inflatable system.
The inflatable body conforms to the surrounding drive profile, helping create an effective seal against irregular underground surfaces. Systems can be manufactured to suit the drive dimensions and application, with options including personnel access and inflation control equipment.
Why use an inflatable ventilation control?
Underground ventilation requirements change as a mine develops. Fixed walls and conventional stoppings can work well where the requirement is permanent, but they can involve considerable labour and time when ventilation arrangements need to change.
An IVC provides a reusable form of mine ventilation control that can be installed, removed and relocated as requirements change. Its flexible construction allows the system to conform to irregular mine profiles while providing a practical restriction or isolation point.
For more background on where this approach fits, see why inflatable systems work in mining.
Common applications
- Temporary and semi-permanent underground ventilation control
- Inflatable stoppings in development and production areas
- Isolation of headings, drives and work zones
- Redirecting airflow as ventilation requirements change
- Reducing unwanted airflow through inactive areas
- Emergency or temporary ventilation isolation
- Applications where a reusable alternative to a constructed stopping is preferred
Built for real site conditions
IVCs are installed in underground environments where access can be limited and profiles are rarely perfect. PolyFusion systems are designed with installation practicality, pressure performance and durability in mind.
Our controlled PVC welding processes support seam integrity and repeatable manufacture, while local production means systems can be configured for site requirements and supported with inspection, modification and repair when required.
Repairability matters when equipment is expected to work in harsh environments. Read more about why repairability should be considered when choosing an industrial inflatable.

Inflatable SystemsFast to deploy and practical underground
An IVC can be transported to the required location in a compact form, positioned within the drive and inflated to conform around the surrounding profile.
Because the unit is flexible, it can accommodate irregularities that would otherwise require additional work when constructing a rigid ventilation barrier. When the ventilation arrangement changes, the IVC can be deflated and removed rather than demolished.
If you are comparing different inflatable approaches, our guide to five questions to ask before choosing an inflatable solution covers some of the practical factors worth considering.
IVC or FlexReg?
Both products control underground airflow, but they do different jobs.
An IVC is primarily used where an opening needs to be substantially sealed or isolated. A FlexReg mine ventilation regulator is designed to leave a controlled opening so airflow can be adjusted by raising or lowering the regulator.
For applications involving pressure-supported plugging or isolation rather than ventilation control, see our Inflatable Plugs & Isolation Systems.
FREQUENTLY ASKED QUESTIONS
Inflatable ventilation control questions
What is an inflatable stopping?
An inflatable stopping is a flexible ventilation control installed across an underground opening to restrict or isolate airflow. PolyFusion refers to its systems as Inflatable Ventilation Controls, or IVCs.
What is a mine ventilation barrier?
A mine ventilation barrier is used to control the movement of air through an underground ventilation network. Depending on the application, this may be a constructed wall, a flexible stopping, an inflatable ventilation barrier or an adjustable regulator.
Can an IVC be reused?
Yes. One of the advantages of an inflatable system is that it can be deflated, removed and relocated where the condition of the unit and the new application allow.
Can personnel access be incorporated?
Yes. Personnel access can be incorporated where regular passage through the IVC is required.
Can an IVC be repaired?
Yes. PolyFusion manufactures and repairs inflatable systems in Western Australia, allowing damaged units to be assessed and repaired where practical.
What information do you need to size an IVC?
The main starting point is the drive width and height, along with the required ventilation function, site conditions and any personnel access requirements.
