Bernardo Aluminium Suction Hose Ø 80 mm 5 m for Metalworking Workshop
The Ø 80 mm aluminium flexible suction hose, extendable up to 5 meters, is designed for fume and dust extraction systems in the metalworking industry. Made from crimped aluminium strip with a reinforced spring steel wire spiral, it ensures flexibility, structural stability, and high temperature resistance. It is suitable for extracting welding fumes, fine dust, and light chips generated by machine tools such as lathes, milling machines, and grinding stations. The nominal diameter of Ø 80 mm ensures compatibility with standard suction inlets and modular ducting. It can be shaped and cut to size, allowing for quick installations even in confined technical spaces.

Frequently Asked Questions
How does the aluminium hose differ from PVC or PU hoses?
Crimped aluminium hose can withstand temperatures up to 250°C — essential for hot fumes, sparks, and incandescent metal dust where PVC would burn and PU would deform. It is conductive (no static charge build-up) and resistant to chemical agents. The disadvantage is its higher weight and less flexibility compared to PU. For metal extractors, paint booths, and fume capture systems on machine tools, aluminium is the correct material.
Does the Ø 80 mm hose connect directly to standard Bernardo extractor fittings?
Yes — Ø 80 mm is one of the standard diameters for extraction systems. Please check that the extractor outlet is the same diameter before purchasing. For coupling with different diameters, use conical reduction fittings. Customer support in Italian available.
What is the purpose of the extendable length from 1.5 m to 5 m?
The crimped spiral structure allows the hose to be extended from 1.5 m (compressed) to 5 m (extended) without joints — useful for connecting machines that are frequently moved or for temporary installations. When compressed, it is compact for storage; when extended, it reaches significant distances without loss of section.
