Efficient Dust Management with Epura Pre-Filtration Systems

In industries where success hinges mainly on the reliability of heavy machinery, effective air filtration is critical. It plays a crucial role not only in ensuring that diesel engines run well, but also in properly protecting employees in the cabins of the machinery. That’s why adding pre-filtration systems is such a strategic solution with so many advantages.

The pre-filtration systems currently on the market are mostly cyclone separators, which slow down airspeed and create a cyclone effect to separate particles. While they are useful for catching larger particles, they still allow finer particles to reach the original filter.

So, what’s the solution for better performance? Innovative, self-cleaning pre-filtration systems that use infrasound for their cleaning cycles.

Epura technology

Epura self-cleaning pre-filtration systems mark a significant step forward in filtration for heavy machinery. Designed to deliver clean air to original filters and significantly extend their service life, Epura systems eliminate the need for frequent filter replacement. That means they also eliminate:

  • the risk of contaminating the air system during filter changes
  • the risk of severe air flow restriction
  • hazardous tasks
  • maintenance-related downtime

Epura Engine and Epura Cabin systems are both designed to integrate seamlessly with original equipment, and they come in a range of sizes and options. Epura Engine systems are sized according to the required airflow, while Epura Cabin systems are available in two models: standard and with activated charcoal, used to filter gases. What’s more, Epura systems require very little electricity to operate, making it easy to add both systems to the same equipment.

Other available pre-filtration systems simply act as particle separators, whereas Epura systems use industrial-grade filters equivalent or superior to the efficiency of the OEM filters. Epura systems also stand out because:

  • they use PTFE-coated filter membranes for efficient cleaning and longer service life
  • they restrict airflow only by around 35% to 50% of the threshold acceptable to manufacturers
  • they incorporate technology (sensors and dashboard) for real-time monitoring of system performance and status
  • they cut down on waste (used filters)

Comparison of existing systems

Conventional pre-filtration systems
Epura pre-filtration systems
Conventional pre-filtration systems often start with a restriction of 25% (12 mbar) as soon as a new filter is installed, immediately reducing their efficiency. This restriction increases rapidly and non-linearly, often peaking at 75–80% of maximum capacity, meaning that the equipment spends most of the time operating with a nearly saturated filter. Epura systems start with a much lower restriction (5 mbar), which increases slowly and can be brought back down after a cleaning cycle, ensuring that the original filter remains clean and functional at all times. This keeps overall restriction low, significantly improving performance and equipment life.

It should be noted that some machinery is sold with pre-filtration systems already installed. However, these systems do not come from the original manufacturer, but are rather aftermarket additions, just like the Epura systems. In these situations, Epura technology stands out by offering a solution specifically designed to optimize the machinery’s performance and durability. In doing so, it helps significantly lower operating costs and improve overall efficiency.

Advantages of the Epura Engine system

By guaranteeing a cleaner air supply, the Epura Engine system allows operators to make full use of engine power, improves fuel consumption, and reduces greenhouse gas (GHG) emissions. It also prevents the air system from being contaminated, which can lead to premature wear, oil contamination, and early failure of engine components.

Advantages of the Epura Cabin system

As for the Epura Cabin system, it significantly extends the service life of the HVAC components in the machinery. It’s a reinforcement that guarantees consistently more efficient temperature control, keeping operators perfectly warm in winter and comfortably cool in summer.

Transferrable system

Last but not least, Epura systems are designed to be transferrable from one machine to another. That means more flexibility and added value for the owner when the time comes to resell or otherwise get rid of their machinery.

In short, Epura self-cleaning pre-filtration systems are a highly effective solution.

With Epura technology, you know you can rely on maintenance-free, self-cleaning pre-filtration systems that reduce the air restriction experienced by original systems.

With an average return on investment of between 6 and 12 months, Epura systems are a sustainable, cost-effective, and environmentally responsible way to truly make the most of your operations.

How does the self-cleaning technology in Epura systems work?

The cleaning is done using a very low sound frequency that lasts around 10 seconds.

How often do Epura systems undergo a cleaning cycle?

The cleaning cycle occurs when the engine is started, e.g., at the start of a shift, after a break, or following any other scheduled equipment shutdown.

Does installing Epura systems affect the equipment warranty?

No, they are pre-filtration systems that ensure a clean air supply without altering the integrity of the equipment.
