For mining operations where explosive atmospheres may be present, ventilation equipment must do more than deliver airflow, it must provide uncompromising safety, regulatory compliance, and reliable performance under demanding operating conditions.

The PreventEx™ range has been developed as a specialised addition to the ToughVent portfolio, specifically engineered for use in underground coal mines and other hazardous mining environments where flammable gases and combustible dusts may be present. Combining proven ToughVent performance with certified flameproof protection, PreventEx™ provides mining operations with a ventilation solution designed to operate safely within potentially explosive atmospheres.

Designed for Hazardous Area Compliance

Safety is the primary consideration in hazardous mining environments. PreventEx™ fans are manufactured to meet stringent industry requirements and are certified to operate in applications where the presence of methane and combustible dusts presents an ongoing operational challenge.

The range is MASC M/26-2037X certified and incorporates several critical safety features designed to minimise ignition risks while maintaining ventilation performance.

At the heart of the design is a certified Group I Flameproof Ex d motor, specifically suited to underground mining applications. This flameproof construction ensures that any internal ignition source remains contained within the motor housing, preventing ignition of the surrounding atmosphere.

Engineered to Eliminate Ignition Risks

PreventEx™ fans incorporate numerous design features focused on reducing the potential for ignition within hazardous environments.

These include:

• Certified Group I Flameproof Ex d motors
• Non-sparking impeller tracks
• Non-sparking construction materials in critical areas
• Precision-engineered tip clearances
• Certified flameproof terminal boxes
• Armoured conduit protection for all electrical wiring
• No exposed electrical connections within hazardous zones

All electrical connections are securely housed and protected through certified flameproof components, ensuring the highest levels of operational safety underground.

Temperature Protection for Explosive Atmospheres

Managing equipment surface temperatures is critical in environments where flammable gases and combustible dusts may be encountered.

PreventEx™ fans are designed to maintain external surface temperatures below the ignition thresholds of common underground hazards.

This temperature management capability provides an additional layer of protection, helping mining operations maintain compliance while reducing risk in hazardous working areas.

Anti-Static Earthing

Full earthing continuity across all rotating and static components, with non-metallic parts meeting the 1GS surface resistance requirement - eliminating static discharge risk in coal dust laden atmospheres as required by SANS/IEC 60079-0

These features work together to minimise the build-up and discharge of static electricity, further enhancing operational safety in potentially explosive atmospheres.

Flexible Installation Options

Recognising that different mining operations have unique infrastructure requirements, PreventEx™ fans are available with multiple electrical connection configurations.

Customers can select from:

• Vector plug connections
• Armoured cable gland connections
• Conduit extension connections

This flexibility allows PreventEx™ fans to be integrated into a wide range of mining methods, electrical systems, and site-specific installation requirements.

Proven ToughVent Performance with Flameproof Protection

While PreventEx™ fans are specifically engineered for hazardous environments, they continue to benefit from the robust design philosophy that defines the ToughVent range.

Mining operations can therefore expect the same focus on:

• Reliable underground performance
• Long service life
• Rugged construction
• Efficient airflow delivery
• Low maintenance requirements
• Comprehensive aftermarket support

The result is a ventilation solution that combines operational performance with the safety standards demanded by hazardous mining applications.

Available Across a Wide Range of Sizes

The PreventEx™ range is available in sizes to suit a variety of auxiliary ventilation requirements, ranging from 572 mm (7.5 kW) through to 1600 mm fan configurations.
