UNI 3.2.1 W3: Self-Cleaning Mobile Filter Unit for Welding Fumes

Self-Cleaning Welding Fume Extraction for Intensive Production Applications

The AerService UNI 3.2.1 W3 is a self-cleaning mobile welding fume extraction system engineered for demanding fabrication environments requiring continuous operation, high airflow performance, and minimal maintenance downtime. Designed for intensive daily use, the UNI 3.2.1 W3 combines W3-certified filtration, automatic compressed-air filter cleaning, and professional source-capture extraction in a robust mobile platform built for production welding operations.

Featuring a high-capacity dual-cartridge filtration system, integrated pre-separation chamber, automatic filter cleaning technology, and advanced digital controls, the UNI 3.2.1 W3 delivers reliable extraction performance for facilities where welding fumes, grinding dust, and thermal cutting particulate are generated throughout the workday.

Why Self-Cleaning Filtration Matters

In high-production welding environments, filter loading can reduce airflow performance and increase maintenance requirements. Traditional manual-cleaning systems often require production interruptions to restore filter efficiency.

The UNI 3.2.1 W3 addresses these challenges through an automatic compressed-air cleaning system that continuously maintains filter performance while reducing operator intervention. This helps:

• Maintain consistent airflow performance.
• Extend filter service life.
• Reduce maintenance downtime.
• Improve overall system efficiency.
• Support continuous production operations.
• Lower long-term operating costs.

By automatically cleaning the filter cartridges during operation, the UNI 3.2.1 W3 is designed to keep fabrication environments running efficiently throughout demanding production schedules.

Designed for Intensive Industrial Applications

The UNI 3.2.1 W3 is built for facilities where welding and fabrication activities occur continuously throughout the day.

Ideal applications include:

• Heavy fabrication shops.
• Manufacturing facilities.
• Production welding operations.
• Structural steel fabrication.
• Industrial metalworking.
• Maintenance and repair operations.
• Fabrication cells requiring continuous extraction.
• Facilities generating both welding fumes and grinding dust.

Unlike entry-level mobile extractors, the UNI 3.2.1 W3 is specifically engineered for intensive-duty applications where reliability and uptime are critical.

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.
• Clogged filter alarm.
• Compressed-air monitoring.
• Automatic Start/Stop functionality.

These features help operators maximize performance while reducing maintenance-related interruptions.

Optimized Airflow Design

The UNI 3.2.1 W3 incorporates several airflow management features to maximize extraction performance.

These include:

• Plug-fan extraction technology.
• Integrated airflow equalizer.
• High-capacity extraction system.
• Dual-stage dust collection.
