Bernardo Flexible Aluminum Duct Ø 100 mm Extendable up to 5 meters
The flexible aluminum duct Ø 100 mm extendable up to 5 meters is designed for ventilation, extraction, and air distribution systems in residential and light industrial applications. Made from multi-layered aluminum foil with a reinforced spiral structure, it guarantees high flexibility, lightness, and mechanical resistance. The corrugated shape allows for linear extension up to 5 m while maintaining stability and flow continuity. Suitable for connecting hoods, extractors, HVAC systems, and air ducts, it allows for quick installation even in confined spaces or irregular paths.

Frequently Asked Questions
How does the aluminum duct differ from PVC or PU ducts?
The crimped aluminum duct can withstand temperatures up to 250°C — essential for hot fumes, sparks, and incandescent metallic dust where PVC would burn and PU would deform. It is conductive (no accumulation of electrostatic charges) and resistant to chemical agents. The disadvantage is its higher weight and lower flexibility compared to PU. For woodworking extractors, circular saws, planers, and light industrial ventilation systems, aluminum is the correct material.
Does the Ø 100 mm duct connect directly to the standard fittings of Bernardo extractors?
Yes — Ø 100 mm is one of the standard diameters for extraction systems. Check that the extractor outlet is the same diameter before purchasing. For coupling with different diameters, use conical reducing 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 duct to be extended from 1.5 m (compressed) to 5 m (extended) without joints — useful for connecting machines that move frequently or for temporary installations. In the compressed position, it is compact for storage; when extended, it reaches significant distances without loss of section.
