Inflatable Ventilation Control Units (VCU)
Ventstop™
The Ventstop Ventilation Control Unit (VCU) is designed to provide a safe, cost-effective and robust alternative to conventional ventilation control for underground mining and tunneling.
The Ventstop is fully portable and inflates in minutes using compressed air and a venturi system. It facilitates blocking off horizontal and/or vertical openings to control dust, fumes, smoke and heat. A control box maintains the internal pressure of the unit over an extended period of time.
The Ventstop can be manufactured to suit any opening shape and dimension and can be installed in horizontal, vertical or inclined openings. The large contact area of the ventilation control units makes them stable in high ventilation pressures. They are suitable for use in metal/non-metal mines and coal mines.
The fabric is high quality and durable. The Ventstop is MSHA Approved for coal mining applications
(MSHA Approval # 07-BA070011).
Ventstop™ Advantages:
- Low material handling

O.P.U Open Access
- Over head protection for maintenance of smelter
- Center passage for men and supplies
- Can be installed in one shift
- Replaced scaffolding that took 6 days to install
Passline O.P.U. System
- A series of Passline cylinders are raised or lowered into voids, secured and then inflated.
- Provides a continuous covering to the walls for the entire surface area of the void
- Prevents free fall of material and some rock ejection situations
- Continuous air intake system keeps unit inflated even if punctured
Passline OPU System inflates to fill voids and provide added safety
Venturi System
- Used for inflating and deflating ventilation control units
- No moving parts
- High density polyethylene that is lightweight and strong
- Fire retardant and anti-static
- Amplifies air volume by up to 25 times
- Use for fast inflation and deflation of ventilation Control units.
