How ECO AIR Works
Mechanical separation + coalescence
Pre-Filtration
Stainless steel mesh captures larger droplets before separation.
Coalescence
Rotating drums enlarge tiny oil particles into larger droplets for efficient separation and oil recovery.
Self-Cleaning & Recycling
Integrated spraying nozzles maintain constant performance and recycle collected oil.
How EARIA Works
Electrostatic filtration
Stainless steel pre-filter
First stage captures larger particles to protect ionizer.
Ionization
High voltage ionizer charges particles for electrostatic capture.
Collector plates
Alternating plates attract and hold charged particles.
Oil particle collection
Self-cleaning drain removes collected oil automatically.
