UNI 3.2.2 W3: Dual-Arm Self-Cleaning Mobile Filter Unit for Welding Fumes with 10' Flex Arms

Self-Cleaning Dual-Station Welding Fume Extraction with Maximum Flexibility

The AerService UNI 3.2.2 W3 with 10' Flex Arms is a self-cleaning mobile welding fume extraction system engineered for fabrication facilities requiring simultaneous source-capture extraction at two welding stations. Combining W3-certified filtration, automatic compressed-air filter cleaning, and dual 10' Flex Arms, this configuration delivers powerful extraction performance while providing exceptional positioning flexibility for multiple operators working in dynamic fabrication environments.

Designed for intensive daily welding operations, the UNI 3.2.2 W3 allows two operators to capture welding fumes directly at the source while sharing a single high-capacity filtration system. The included 10' Flex Arms (3m) provide outstanding maneuverability and adaptability, making this configuration ideal for fabrication facilities where workpieces, weld locations, and workstation layouts frequently change throughout the day.

Why a Dual-Arm Setup?

Many fabrication facilities operate multiple welding stations within the same work area. Installing a dedicated extraction unit at every workstation can increase equipment costs, consume valuable floor space, and create additional maintenance requirements.

The UNI 3.2.2 W3 addresses these challenges by allowing two operators to share a single high-capacity filtration system while maintaining effective source-capture extraction at each workstation.

Benefits of a dual-arm setup include:

• Simultaneous extraction for two welding stations.
• Reduced equipment investment compared to multiple extraction units.
• Lower maintenance requirements.
• More efficient use of floor space.
• Increased productivity in multi-operator environments.
• Flexible extraction coverage across multiple work areas.
• Centralized filtration with simplified service and maintenance.

For fabrication shops, manufacturing facilities, and welding cells where multiple operators work in close proximity, a dual-arm extraction system provides an efficient solution for maintaining air quality while maximizing equipment utilization.

Why Choose 10' Flex Arms?

The 10' Flex Arm configuration is designed for facilities where versatility and positioning flexibility are critical.

Benefits include:

• Maximum arm maneuverability.
• Easy positioning around complex weldments.
• Quick adjustments during fabrication.
• Excellent reach across multiple work areas.
• Improved access to difficult-to-reach weld locations.
• Ideal for changing workstation layouts and custom fabrication projects.

This configuration is particularly beneficial for fabrication environments where workpieces and welding positions frequently change throughout the day.

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 workday.

Ideal applications include:

• Heavy fabrication facilities.
• Manufacturing plants.
• Production welding operations.
