Weldclass ALLCLEAR MA350 AUTO 3PH/415V with Twin 3m Arms 91350AMA3

Heavy-duty twin-arm extraction unit ideal for welding, grinding, cutting, and gouging fumes. Operates on 415V 3-phase power for high-performance industrial use. Twin 3-metre arms provide broad reach and minimize the need to reposition the main unit. Automatic filter cleaning system activates on shutdown or when airflow drops, saving downtime. Cleanable dual cartridge filters offer longer lifespan and lower operating costs compared to traditional box filters. Pulse-cleaning system uses compressed air bursts to maintain filter condition and airflow efficiency. Spark deflection plate redirects hot debris to a dust bin, reducing fire risk and extending filter life. 28m² nanofiber filter surface area delivers high filtration efficiency and longer service intervals. Patented dust collection bin enables safe removal of filtered dust while unit is running—preventing work interruption. Exhaust air is directed upwards to reduce dust disruption in the surrounding environment. Arcrobat arm joints and heat-resistant hoses built for durability and long-term use. Lightweight yet tough suction hood with wide inlet for efficient fume capture. Includes hour meter, filter fullness indicator, and malfunction warning system for user safety and efficiency. Low operating noise at 74 dBA with integrated acoustic sponge insulation. Compact and mobile form factor with ergonomic access to controls and filters. Backed by a 7-Year Warranty Offer*.
