W3-Certified Filtration Performance
The UNI 3.2.1 W3 is certified to W3 filtration standards with filtration efficiency exceeding 99%, making it suitable for demanding welding fume extraction applications.
The filtration system utilizes:
Pre-Separation Chamber
Incoming air enters a dedicated pre-chamber designed to separate heavier dust and sparks before they reach the primary filtration cartridges. This reduces filter loading and improves overall system performance.
Dual Cartridge Filtration
The system incorporates two high-capacity cartridge filters utilizing Sintexx Plus nanofiber media, providing exceptional filtration efficiency and extended service life.
Automatic Compressed-Air Cleaning
The integrated reverse-pulse cleaning system automatically removes accumulated particulate from the filter surface, maintaining airflow performance without requiring manual cleaning procedures.
Advanced Digital Control System
The UNI 3.2.1 W3 features a digital control panel designed to simplify operation and provide real-time system monitoring.
Features include:
- Multi-language interface.
- Hour meter.
- Alarm history log.
- Filter status monitoring.
