Metal hoses
Flexible metal suction hoses made of galvanized or stainless steel, in accordance with the requirements of the ATEX directive, with very high mechanical and thermal resistance, intended for extracting gaseous media at high temperatures and for transporting loose materials causing high abrasion.

Tolerance for the parameters contained in this catalog is approx. 5% (despite diameters). All parameters apply for room temperature. To discharge static electricity, ground the spiral. It is possible to make a hose with a non‑standard diameter (not included in the basic offer) on a special request. The standard lengths of the hoses are measured while maximum extension. In case of cutting metal hoses, ends must be secured against unwinding (e.g. by welding). Note! Polygonal construction of the hose doesn’t provide 100% tightness. For exhaust of fumes we recommend using a diameter three times larger than the diameter of the outlet and using the exhaust fan to avoid gas escape.
