Foodstuff hoses and pharmaceutical hoses

In this section, we would like to assist you with the selection of the appropriate foodstuff hose or pharmaceutical hose. In the following, we have compiled an initial selection of the most suitable hoses from our range for the conveyance of food and the transportation of pharmaceutical products . All listed products marked with the FOOD icon are food safe, taint-free and odourless. For further information about our range of hoses for the food and pharmaceutical industries see below.

Foodstuff hoses and pharmaceutical hoses

Applications and properties
Food hoses are suitable for a variety of uses in the food industry due to their properties. They are used for conveying food such as rice, sugar, coffee, tea or grain in silos, silo vehicles and tank trucks. They are also frequently used in packaging machines, mixers and dryers for big bag filling and emptying. Due to their food-grade walls and other important properties, these hoses are also suitable for use in the pharmaceutical industry. This includes their use in vacuum conveyors, suction conveyors, dosing systems and tablet presses. Our food-grade hoses are odorless and tasteless, resistant to microbes and hydrolysis, as well as resistant to oils and chemicals. Hose types with the designation AS are also antistatic, which is very important for conveying flammable goods and for use in explosion-hazardous areas.
The following hose types are particularly suitable for food conveyance: AIRDUC^® PUR-INOX 355 FOOD-AS (HD), AIRDUC^® PUR-INOX 356 FOOD-AS (XHD) / PUR 356 FOOD (XHD) / PUR 356 FOOD REINFORCED (XXHD), but also BARDUC^® PUR-INOX 382 FOOD-AS (XHD).
The PROTAPE^® PUR-C 335 FOOD-AS FLAT  and the AIRDUC^® PUR-INOX 355 FOOD-AS (HD) are particularly suitable for use on mixers, dryers and packaging machines.
The products CP PUR 455 FOOD, PROTAPE^® PUR 330 FOOD (LD), PROTAPE^® PUR-INOX 330 FOOD-AS (LD), AIRDUC^® PUR 350 FOOD-AS (MD) / PUR 351 FOOD (MD) / PUR-INOX 351 FOOD-AS (MD) / PE 362 FOOD (MD) and CP PTFE-INOX 475 FOOD can be used as alternatively usable hoses.

Frequently asked questions
Which hoses are antistatic and why is this important?
All hoses bearing the abbreviation AS in the product name, such as the AIRDUC^® PUR-INOX 355 FOOD-AS (HD). In the case of hoses which are not antistatic, electro-static charging occurs due to the friction of the material against the wall and the friction within the medium. In the case of flammable raw materials, that can lead to an ignition or even explosion of the raw material. The use of antistatic hoses can prevent this risk.

Can the hoses be safely used to convey food and be used in clean rooms?
All hoses in this section can be used in clean rooms and can be safely used for food such as rice, sugar, milk powder, coffee, tea, cereals and other dry foods. Frozen foods can also be conveyed.
