Another advancement in our DPF systems.

At HJS Emission Technology SA, we’re continuously looking for ways to improve the durability, reliability and performance of our emission control solutions.

We now incorporate Westfalia GTH metal hoses into our DPF systems, providing a durable and secure connection designed to withstand the demanding conditions of heavy-duty and mining applications.

It’s another detail that contributes to a robust, fit-for-purpose system built for the environments our customers operate in.

Not all Diesel Particulate Filters are built the same.

When it comes to operating in demanding mining and industrial environments, filter design makes all the difference.

HJS SMF® (Sintered Metal Filter) technology offers:
- Up to 3x greater ash storage capacity than conventional cellular filters
- High filtration efficiency for cleaner emissions
- Multi-directional flow distribution for improved performance
- Lower backpressure to support engine efficiency

The result? Longer service intervals, reduced maintenance requirements, and a filtration solution engineered for the harshest operating conditions. These benefits are highlighted throughout the carousel, including the comparison of SMF® and cellular filter structures and their respective performance characteristics.

As the OEM for HJS mining solutions, HJS SA supplies and supports original, certified SMF® systems designed to help fleets operate cleaner, safer, and more efficiently.

Trusted globally. Engineered locally. Delivering cleaner air underground.

As the HJS Group's certified Global Mining OEM, HJS Emission Technology South Africa is proud to design and deliver customised diesel emission solutions that help underground mines meet stringent Occupational Exposure Limit (OEL) requirements while improving operational efficiency.

Our proven DPF technologies are engineered to:
- Achieve measurable DPM compliance
- Minimise capital expenditure and machine downtime
- Provide proven, locally supported OEM solutions
- Support ESG goals through reusable, long-life filtration systems

Backed by global HJS expertise and local engineering, we're helping mines create safer working environments, extend equipment life, and protect the health of underground personnel.

The true cost of a DPF isn't the purchase price - it's the maintenance strategy behind it.👏

For underground mining operations, every hour of downtime and every replacement component adds to the total cost of ownership. That's why HJS SMF® Diesel Particulate Filters are engineered differently.

Instead of replacing filter elements, HJS SMF® technology allows operators to clean the filter with water and return it to service, making routine maintenance both simple and cost-effective.

Key advantages include:
• Cleanable with a standard pressure washer
• No routine filter replacement required
• On-site maintenance capability
• Reduced maintenance costs and downtime
• Long service life in demanding mining environments

Designed for reliability, HJS SMF® systems help mining operations maintain high particulate filtration performance while lowering lifecycle costs and simplifying maintenance.

At HJS SA, we believe emission control solutions should be engineered for long-term performance, not ongoing replacement.
