Expel removes 99.999% of liquid water, oil emulsion fluids, and solid particulates to 1 micron. The 3-in-1 solution has eradicated all the site’s air contamination issues. Installing one Expel unit at the point of use in the bitumen area and another before the solenoid control panel ensures these critical areas are always protected.

Aggregate Industries is committed to decarbonising its operations. Plant Manager Dave Owen is exceptionally proactive and keen to reduce the energy usage of sites under his management. Expel is the first compressed air filter that offers the additional benefit of energy-efficient and sustainable compressed air filtration.

Conventional filters generate ongoing part replacement and maintenance to service them. As the internal elements of traditional filters become saturated, they gradually become more energy-draining because a greater volume of compressed air is required to pass through the elements. Expel provides a consistently low-pressure bar drop. Rather than retaining any liquids or solid particulates, it uses physics to separate the contaminants from the air. Expel then discharges the impurities into an AVG Auto Drain. Therefore, Expel’s performance will not reduce over time, and energy usage will remain consistently low.

The Results:

Increased Sustainability: The site stopped using wasteful filters that required disposable and energy-draining replacement filter elements. By switching to Expel, the site eliminated equipment damage caused by inadequate filtration products. The plant drastically reduced the amount of equipment going to landfills.

Reduced Costs: Expel has reduced the site’s energy bills and maintenance costs by eradicating three primary sources of compressed air contamination.

Reduced Downtime: Expel stopped moisture from reaching the solenoid valves and bitumen area, ensuring continual and optimal operation. Removing moisture also eliminated production downtime caused by ice blockages in the pneumatic lines.

Superior Equipment Protection: Expel filters do not contain disposable internal elements, so their performance remains 99.999%. Therefore, Expel guarantees the protection of pneumatic equipment to the highest standard.
