Extraction arm – DIY welding fume extractor

3D CAD models free download and CAD drawings – download 3D & 2D complete professional CAD projects

    This model of extraction arm has been designed with an external carrier pantograph – similar to Nederman Extraction arm NEX S type. Flexible tube is attached to the skeleton by straps. It is easily removable and can be replaced in any time.  Open support arm system and hood of acid proofed polished stainless steel requires a minimum of maintenance and makes it easy to clean. This free CAD design could be used for DIY welding fume extractor, or fume extractor.

A complete free CAD project can be downloaded by anyone without creating an account. CAD documentation contains 3D CAD assemblies, free 3D CAD models and 2D drawings. We have been developed free CAD drawings for direct download from our site.

Prepared documentation types are separate sets of 3D free CAD models and assemblies, 2D CAD drawings.
