High Airflow Capacity
Up to 2,750 m³/hr airflow to handle multiple machining operations simultaneously
HEPA Filter Option
Optional HEPA post-filter achieves 99.95% particle removal for cleanroom applications
Self-Cleaning
The built-in spray nozzles allow the collection system to be cleaned without removing the module
Advanced Corona Discharge Technology
Superior separation for fine particles, smoke, sub-micron oil mist, and industrial odors where mechanical filters reach their limits.
Advanced corona discharge technology for fine particle separation. Ideal for smoke, sub-micron oil mist, and industrial odor control. Electrostatic filtration ionizes and captures particles on collector plates with high separation efficiency where conventional filters struggle.
Applications:
Machining with high-speed tools
Smoke from cutting fluids
Industrial soldering & welding
Chemical & pharmaceutical processes
Electrostatic Technology
Ionizes and captures sub-micron particles (including smoke) on collector plates. Achieves high separation efficiency where conventional filters struggle.
Low Maintenance Operation
Robust ionizer design with optional self-cleaning system. Reduces manual cleaning cycles and extends service life.
Industry 4.0 Ready
Premium version includes Siemens Touch-Panel, PROFINET/PROFIBUS connectivity, and real-time parameter monitoring for smart factory integration.
Compact & Flexible
818 × 466 × 566 mm footprint. Easy to retrofit. Optional Service Trolley allows on-site cleaning without module removal.
High-Efficiency Dust Collection for Dry Processes
Reliable cartridge and baghouse solutions for heavy dust loads from woodworking, metal grinding, and bulk material handling.
Our dust filtration systems are engineered for dry dust applications. Using advanced media technology and pulse-jet cleaning, they deliver consistent airflow and long filter life — even in the most demanding industrial settings.
Applications:
Woodworking
Metal Grinding
Minerals Processing
Food & Grain
Pharmaceuticals
Modular Design
Scalable cartridge and baghouse configurations to match your airflow and space requirements.
Pulse-Jet Cleaning
Automatic compressed-air cleaning maintains low pressure drop and extends filter life.
Explosion Protection
Optional ATEX-certified components for safe operation in combustible dust environments.
Multiple Filtration Media
Choose from cellulose, polyester, or PTFE membranes for optimal efficiency with your specific dust type.
Choose the Right Filtration Technology for Your Process
Whether you handle oil mist, emulsions, smoke, or ultra-fine aerosols — our self-cleaning filtration systems deliver cleaner air, lower maintenance, and stable performance.

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.
