CFT Ventilation Solutions – High-Efficiency Industrial Air Filtration for Mining Environments
Description
The CFT Ventilation Solution range is designed to deliver high-efficiency filtration for mining and industrial ventilation systems where dust control is critical to equipment reliability and operational safety.
These systems are commonly used in room pressurisation and industrial ventilation applications, where clean air must be maintained in extremely dusty environments.
Engineered for Extreme Mining Conditions
The CFT ventilation solution range is manufactured according to specific application requirements, with a choice of three vortex tube configurations to suit different airflow and dust load conditions.
These high-efficiency vortex tubes are typically used as pre-filters ahead of pocket filter systems, reducing the dust burden before fine filtration occurs.
Proven in Real Mining Applications
In a large limestone mining operation in South Africa, dust contamination created a serious operational risk inside an onsite electrical substation.
During normal mining and processing activities:
- Blasting and crushing released large volumes of fine dust.
- Dust was drawn into the substation through natural airflow and unsealed openings.
- Accumulation of dust on electrical components increased the risk of calcified bridging and “spark-over” failures.
- This posed a direct threat to critical infrastructure powering the plant.
The result was a clear operational challenge:
How do you protect sensitive electrical systems in one of the dustiest environments in mining?

The CFT Ventilation Solution
To address this, a two-stage filtration and pressurisation system was implemented using CFT technology.
The system works by:
- Filtering incoming air using a CFT pre-filtration stage.
- Passing air through a high-efficiency pocket filter.
- Supplying clean air to pressurise the substation room.
By maintaining positive pressure inside the substation, dust is prevented from entering through doors, seals, and natural infiltration points.
Why the CFT Ventilation Solution is Critical
While pocket filters are designed to remove fine particles in the 0.1–10 μm range, using them directly on raw mine air would be inefficient and costly.
The CFT pre-filter:
- Removes up to 92% of particles larger than 5 μm.
- Dramatically reduces dust load before fine filtration.
- Extends pocket filter service life significantly.
- Ensures fine filters operate at their intended efficiency.
This combination allows the system to deliver clean, pressurised air in high-dust environments without excessive maintenance costs.
Durable Construction for Harsh Environments
CFT ventilation solutions are manufactured from:
- Mild steel sheet metal.
- Full internal and external powder coating.
This ensures long-term durability in harsh mining and industrial environments while maintaining consistent performance.
Installation and Maintenance Advantages
- No fabrication required during installation.
- No daily maintenance required (if scavenge system is functional).
- Weekly inspections recommended for scavenge system condition.
- Dust handling via blow-through or fan-assisted scavenge system.
Benefits of the CFT Ventilation Solution Range
- Extended filter life across both pre-filter and pocket filter stages.
- Reduced downtime in critical electrical environments.
- Lower maintenance and operational costs.
- Improved reliability of electrical infrastructure.
- No moving parts in the pre-filter system.
- Proven effectiveness in real mining substation applications.
Frequently Asked Questions about the CFT Ventilation Solution Range:
What is the CFT Ventilation Solution used for?
The CFT Ventilation Solution is used to provide clean, pressurised air in mining and industrial environments, particularly in applications such as electrical substations where dust control is critical for safe and reliable operation.
How does the CFT system protect electrical substations?
The system filters incoming air using a two-stage process (CFT pre-filter + pocket filter) and then pressurises the room. This prevents dust from entering through gaps, seals, doors, and windows, reducing the risk of electrical failures such as spark-over events.
Why is a pre-filter important in the ventilation system?
The CFT pre-filter removes a large portion of dust particles before air reaches the fine pocket filter. This reduces filter loading, extends filter life, and ensures the fine filtration stage is used efficiently for smaller particles only.
