UNI 3.2.2 W3: Self-Cleaning Mobile Filter Unit for Welding Fumes

Self-Cleaning Welding Fume Extraction for Multi-Station Production Environments

The AerService UNI 3.2.2 W3 is a self-cleaning mobile welding fume extraction system designed for fabrication facilities requiring source-capture extraction at two welding stations simultaneously. Engineered for intensive industrial applications, the UNI 3.2.2 W3 combines W3-certified filtration, automatic compressed-air filter cleaning, and dual-arm extraction capability to deliver reliable fume control in demanding production environments.

Built around the same industrial platform as the UNI 3.2.1 W3, the dual-arm UNI 3.2.2 W3 increases workstation flexibility by allowing extraction from two separate welding positions while maintaining high-efficiency filtration and continuous-duty operation. This makes it an ideal solution for fabrication shops seeking to maximize extraction coverage without adding additional filtration units.

Why Dual-Arm Extraction?

Many fabrication facilities operate multiple welding stations within the same work area. Installing a dedicated extraction system for every station can increase costs, consume valuable floor space, and complicate maintenance requirements.

The UNI 3.2.2 W3 provides a centralized mobile solution capable of supporting two extraction arms from a single filtration unit.

Benefits include:

• Coverage for two welding workstations.
• Improved equipment utilization.
• Reduced floor space requirements.
• Lower maintenance costs compared to multiple units.
• Flexible workstation positioning.
• Increased productivity in multi-operator environments.

The dual-arm design helps facilities maximize extraction coverage while maintaining operational efficiency.

Designed for Intensive Industrial Applications

The UNI 3.2.2 W3 is built for fabrication environments where welding, grinding, and thermal cutting activities occur continuously throughout the day.

Ideal applications include:

• Heavy fabrication facilities.
• Structural steel fabrication.
• Manufacturing plants.
• Production welding operations.
• Multi-station welding cells.
• Industrial maintenance departments.
• Metal fabrication shops.
• Facilities generating welding fumes and grinding dust.

Its dual-arm configuration makes it particularly effective in environments where multiple operators require simultaneous fume extraction.

W3-Certified Filtration Performance

The UNI 3.2.2 W3 is certified to W3 filtration standards with filtration efficiency exceeding 99%, providing high-performance welding fume filtration for industrial applications.

The filtration system includes:

Pre-Separation Chamber

A dedicated pre-separation chamber captures heavier dust and sparks before they reach the primary filtration cartridges, helping extend filter life and maintain airflow performance.

Dual Cartridge Filtration

Two high-capacity cartridge filters utilizing Sintexx Plus nanofiber media provide exceptional particulate capture efficiency while supporting continuous-duty operation.

Automatic Compressed-Air Cleaning

The integrated reverse-pulse cleaning system automatically removes accumulated particulate from the filter surface, reducing maintenance requirements and helping maintain consistent airflow.

Advanced Digital Control System

The UNI 3.2.2 W3 features a digital control panel designed to simplify operation and monitor system performance.

Features include:

• Multi-language interface.
• Hour meter.
• Alarm history log.
• Filter monitoring.
