NORRES officially lists this antistatic vacuum cleaner hose for industrial vacuum cleaners, vacuum cleaners, swimming pool cleaning, scrubbers and floor cleaning machines.

NORRES EVA 373 AS is an EVA hose with a self-supporting profile design and open profile geometry. The hose wall is made from EVA. NORRES specifies this model as lightweight, highly flexible, crush resistant and floatable.

NORRES specifies a surface resistance below 10¹¹ Ω and good resistance to alkalis and acids. The official operating temperature range is from -25°C to +65°C. The standard colour is black.

NORRES states that EVA 373 AS is in accordance with ATEX 2014/34/EU and German TRGS 727 for aspiration of combustible dusts in Zone 22 inside the hose, conveying of non-flammable liquids, use in Zone 1 and Zone 2 for gases, and use in Zone 0 for gases. The complete system design and actual installation requirements must be checked before selection.

The current official technical table lists a recommended vacuum value of 0.5 bar for the available standard variants. The bending radius varies by hose size and must be checked against the official technical table before use.

Our team can assist customers throughout Malaysia with NORRES hose selection based on hose diameter, conveyed material, operating temperature, airflow, vacuum condition, installation length and quantity requirement.
