301046 - Miller Low Profile Fume Extraction Hood 6-Inch

Optimized Source Capture for Restricted Spaces

The Miller 301046 Low Profile Extraction Hood (6x6) is a specialized accessory engineered to enhance the versatility and efficiency of industrial fume extraction systems. In the realm of source capture, the geometry of the hood plays a critical role in defining the capture zone—the area in front of the hood where air velocity is sufficient to overcome ambient air currents and thermal buoyancy of the welding plume. Standard bell-mouth hoods, while effective, often present physical obstructions in complex fabrication setups. This low-profile variant addresses those geometric constraints without compromising aerodynamic performance.

Designed specifically for integration with 6-inch diameter extraction arms, such as those found in the Miller Filtair® and SWX series, this hood features a streamlined 6x6 inch inlet profile. This reduction in vertical footprint allows operators to position the extraction point closer to the arc in confined spaces, such as inside vessel compartments, around complex jigs, or under low-hanging obstructions. By enabling closer proximity to the source, the system can achieve higher capture velocities with the same volumetric airflow (CFM), thereby improving the overall capture efficiency of hazardous particulates like hexavalent chromium and manganese.

Constructed from durable, industrial-grade materials, the 301046 hood is built to withstand the rigors of daily welding operations, including exposure to heat, spatter, and UV radiation. Its lightweight design ensures that it does not impose excessive torque on the extraction arm's friction joints, maintaining ease of articulation and stability during use. For facility managers and safety officers, equipping extraction arms with task-specific hoods like the 301046 demonstrates a commitment to both air quality compliance and operational ergonomics.
