301046006 - Miller 6x12 Low Profile Fume Extraction Hood

Precision Source Capture for Restricted Spaces

The Miller 301046006 Low Profile Extraction Hood is a specialized accessory engineered to enhance the versatility and effectiveness of Local Exhaust Ventilation (LEV) systems in industrial welding environments. Measuring 6 inches by 12 inches, this rectangular hood is specifically designed to address the challenges of capturing welding fumes in confined or geometrically complex spaces where standard conical hoods may be obstructive or ineffective. By flattening the capture profile, Miller Electric provides a solution that maintains high face velocity and efficient particulate entrainment without compromising the welder's access to the workpiece.

Effective source capture is the most efficient method for controlling worker exposure to hazardous airborne particulates, such as hexavalent chromium, manganese, and nickel. The geometry of the 301046006 hood allows it to be positioned in close proximity to the arc—the generation point of the plume—thereby maximizing the capture efficiency while requiring lower total volumetric airflow compared to general ventilation solutions. This proximity is crucial because capture velocity decreases exponentially with distance; the low-profile design enables the hood to sit closer to the weld joint without interfering with the welding torch or the operator's line of sight.

Constructed from durable materials capable of withstanding the thermal radiation and physical demands of heavy manufacturing, this hood integrates seamlessly with compatible Miller fume extraction arms, such as those found in the Filtair series. Its aerodynamic design minimizes turbulence at the intake, ensuring a smooth laminar flow that effectively draws in the thermal plume. For facility managers and safety officers, equipping extraction arms with the appropriate hood geometry is a key step in ensuring regulatory compliance with OSHA and ACGIH standards. The 301046006 represents a targeted engineering control for difficult-to-reach welds, ensuring that safety protocols are maintained regardless of the workpiece complexity.
