Spiral Hose Poly Urethane Antistatic Food Contact Compliant Inox spiral Robust – Bends is a flexible spiral reinforced hose/ducting for transport of explosion hazardous abrasive dust, powder, fibers, air, gasses, and liquids. This hose is tested to be suitable for direct contact with food and pharmaceutical products, such as sugar, milk powder, rice, cereals, coffee, chocolate, grains, tea, flour, frozen foods. This hose is suitable for explosion hazardous environments due to its electrostatic conductive properties. The hose can be used for extraction arms, long distances to connect tubing machinery or components. The 2:1 compressible ratio allows for telescopic features such as big bag handling stations. The Poly Urethane material is suitable for contact with food according to American and European food contact regulations, the spiral reinforcement is made in Stainless Steel. The metal spiral reinforcement allows for great harmonica like telescopic compressible features. Due to the spiral the folds are consistent, and no irregular pleads will form, preventing material fatigue.

Overpressure and under pressure are recommended threshold operating values, products can be subject to higher loads upon request. The bending radius is measured through the inside of the hose arch. The right to make technical modifications is reserved. All values determined at 20°C and are approximate data.
