Unlike conventional cyclones using high velocity and high pressure, this uniflow deduster has a low velocity and low pressure to separate particles in air streams and to achieve high efficiency in particle separation and low energy consumption.
On-going research include application of the technology to reducing pollutant emission from animal buildings, and cleaning air entering the cooling systems and engines of off-road machinery.
Principles of Aerodynamic Deduster
Vanes create rotational airflow with minimum turbulence Impacting forces separate particles from air stream
Operating features
High air cleaning efficiency, operating without filtration media, Low pressure drop (50-200 Pa).
Off-road machinery air cleaning
Dust removal by mass:75-92%
Ammonia removal: 15-48%
Higher efficiency at higher retention time and water consumption.
For off-road machinery
Dust removal by mass: 70-80%
Below is a Deduster designed for Precleaning Intake Engine Air  for large diesel engines.
