Blower hoses made of EPDM/PP, NBR/PVC, PUR, and PVC belong to the group of blower and ventilation hoses used in laboratories and industrial environments
Blower hoses are primarily used as suction and pressure conduits made from PUR and PVC. Among them are food-grade, dairy and wine hoses, typically designed in spiral form. PUR and PVC blower hoses are widely used in the food industry, where their material properties make them especially suitable for transporting food products. To qualify as food-grade, they must meet the strict requirements of the FDA and European regulations for food-contact materials. These hoses are characterized by their neutral taste and physiological safety.
A special subgroup includes foil hoses, which are also available in FDA-compliant versions and are specifically used in cleanroom technology.
Chemical resistance of blower hoses
- EPDM/PP (Ethylene-Propylene-Diene Rubber/Polypropylene, Santoprene/THOMAPREN/Norprene)
This compound is resistant to alcohols as well as diluted acids and alkalis.
Conditionally resistant to aliphatic hydrocarbons.
- NBR/PVC (NBR/PVC compound)
The inner layer made of NBR is resistant to alcohols, aliphatic hydrocarbons, gasoline and diesel fuels, hydraulic oils, mineral oils and greases, diluted acids, diluted alkalis, and hot water.
- PUR (Polyurethane/Vulkollan)
Offers excellent resistance to lubricants, gasoline, and other aliphatic hydrocarbons, as well as to organic and mineral acids, alkalis, amines, and hot water.
It is only conditionally resistant to benzene, xylene, and other aromatic hydrocarbons, esters and ketones, as well as oxidizing acids like nitric acid.
- PVC (Polyvinyl chloride/THOMAVINYL)
Resistant to lubricants, gasoline, and other aliphatic hydrocarbons, as well as organic and mineral acids, alkalis, amines, and hot water.
PVC is less resistant to benzene, xylene, other aromatic hydrocarbons, esters, ketones, oxidizing acids such as nitric acid, and UV radiation.
Temperature resistance of blower hoses
This category includes elastomers and soft plastics:
- PUR (Polyurethane/Vulkollan):
-20 °C to +80 °C
- PVC (Polyvinyl chloride/THOMAVINYL):
-10 °C to +60 °C
- EPDM/PP (Ethylene-Propylene-Diene Rubber/Polypropylene, Santoprene/THOMAPREN/Norprene):
-40 °C to +120 °C, short-term up to +150 °C
- NBR/PVC (NBR/PVC compound):
-15 °C to +65 °C
Specific properties
- EPDM/PP blower hoses
Suitable for hot air, hot gases, flue gases, and chemical vapors; robust and mechanically strong.
- NBR/PVC blower hoses
Weather- and aging-resistant, robust and impact-resistant; excellent chemical resistance to gasoline, oils, and diluted acids and alkalis.
- PUR blower hoses
Designed as suction and pressure hoses for conveying liquid, powdery, and granular media – including milk powder, sugar, and granulates. These hoses are extremely wear-resistant, robust, and mechanically strong. Special compounds meet FDA and BfR requirements, as well as the European Pharmacopoeia. Their superior flexibility and abrasion resistance make them ideal for dynamic systems.
- PVC blower hoses
Offered as spiral and corrugated hoses with high mechanical strength, flame-retardant properties, and anti-adhesive surfaces.
As corrugated hoses, they are used as suction and pressure hoses – specifically for transporting fatty and non-fatty foodstuffs depending on hose type. Transparent PVC hoses are commonly used in dairy processing, enabling visual flow monitoring and easy cleaning. Their smooth inner surface prevents deposits and bacterial growth – essential in dairy applications.
RCT offers blower hoses in the following specifications:

Cleaning of the hoses
Food hoses are typically cleaned using CIP systems (Cleaning in Place) with specialized detergents at temperatures up to 80 °C. Both PUR and PVC exhibit good resistance to common cleaning agents and retain their mechanical properties even after frequent cleaning cycles. Nevertheless, regular inspections and timely replacements are essential to ensure product safety.
