MW7500 Wall Mounted Welding Fume Extraction Unit with 4 Metre Arm

Why Buy MasterFlex Welding Fume Extraction Arms?

The new MasterFlex series, thanks to the materials used and design innovation, provides the operator with high manoeuvrability and stability, guaranteed by a system of Belleville washers which supports the fume extraction arm.

The internal load bearing structure is manufactured with reinforced steel tubing and 6061 aluminium components CNC machined from single blocks to achieve T6 properties, then anodised to guarantee durability over time, despite continuous exposure to fumes.

The flexible cover hose is a multilayer PVC to guarantee protection from any sparks and resistance to high temperatures (max 140 °C).

The extraction hood, with high uptake for maximum efficiency of extraction, includes a manual damper to regulate airflow, anti-intrusion grille protection and handle.
