Air Purification Technologies

With over 30 years’ expertise in innovative dust management solutions for heavy industry, Propulsa Innovations has developed an air pre-filtration system that uses a low-frequency self-cleaning system.

With the aim of adapting its technology to different industries, the company intends to become the must-have solution for heavy equipment users looking for healthy air management.

Epura System

The technology developed by Propulsa Innovations exponentially increases filter replacement intervals, reducing vehicle downtime and increasing fleet availability in original systems, while surpassing their performance in very dusty environments.

Dust-laden air enters through the base of the Epura systems and passes through a high-efficiency filter, equipped with a Spunbond membrane coated with PTFE. When the Epura system’s filter reaches a saturation level, a cleaning cycle using low-frequency sounds becomes necessary. This is done by stopping and restarting the equipment’s engine, which cleans the filter without any real interruption, with the cleaning cycle lasting an average of 10 seconds.

These innovative systems can be installed on operation cabins (Epura Cabin) and on the air intakes of diesel engines and other industrial filtration equipment (Epura Engine).

Epura Engine
