ASPRA technology is a powerful, effective and sustainable electrostatic air filtration technique. The ASPRA air purifiers remove dangerous and contaminating substances from the air. Chronical illnesses and infection outbreaks can be prevented or reduced with air purification. Besides that, odour nuisance can also be prevented or reduced.

The ASPRA air purifier removes:

  • Coarse dust
  • Particulate Matter (PM10 en PM2.5)
  • Ultrafine Particulate Matter (PM1, PM0.1, submicron- and nanoparticles)
  • Microbiological contamination (viruses, bacteria, fungi, spores and pollen)
  • VOC’s (volatile organic compounds) and smells
    (Optional with the Activated Carbon Filter)

The ASPRA is a revolutionary application for air purification. The system applies a very high air purification efficiency (up to E10-11/HEPA classification according to NEN-EN 1822 standard), without using a HEPA filter. As a result, the ASPRA has 80% less pressure drop compared to conventional filters, hereby realizing substantial energy savings compared to conventional filters. The ASPRA only charges particles inside the application, and captures them directly on the own open structure filter (a collector). No harmful radicals are produced. 

The ASPRA is a modular system with diverse models and application possibilities. It is available in various standard versions, but can easily be customised to the specific requirements of the customer. Providing custom made solutions to ensure an optimal solution.

Indoor air purification (recirculation)

The ASPRA air purifiers recirculate and purify the air in the room. The air purifiers remove coarse dust, particulate matter and ultrafine particulate matter. Besides that asbestos, pollen, fungi, bacteria and viruses are removed from the air. It is possible to also remove VOC’s, gasses and odours

Viruses, bacteria and fungi are biological particles. The air purifier blows the particles through an electric field. Biological particles are eliminated in this electric field and dust gets charged. The loaded particles are attracted on the outside of the purifier. This removes the charged particles from the air stream. The last contaminations are removed from the air stream in the collector. This reduces the risk of spreading. Our air purifiers are suitable for people who need clean air, but do not want high energy usage and high maintenance costs.

ASPRA benefits:

  • High efficiency purification.
  • Low energy consumption.
  • User-friendly.
  • Safe maintenance.
  • Low maintenance costs.
  • 99% purifying capacity, without HEPA filters.
