NORRES EVA 373 EC
Electrically conductive EVA vacuum hose for ATEX – NORRES EVA 373 EC
The EVA 373 EC from NORRES is a lightweight, electrically conductive vacuum hose made of EVA plastic, developed for industrial and potentially explosive environments.
The hose is suitable for vacuum cleaners, industrial cleaning, pool cleaning and the transport of dust, powders, fibres and gases – where ATEX Zone 22 safety is required.
Lightweight, flexible and robust
The hose is extremely light, highly flexible, floatable and crush-resistant.
It floats on water and offers excellent resistance to acids and alkalis.
Perfect for both mobile and stationary use where flexibility and durability are essential.
Approvals and properties
EVA 373 EC has a surface resistance below 10⁶ Ω, complies with ATEX 2014/34/EU and TRGS 727 for Zone 22 and Zone 1/2 (gases).
The hose is RoHS and REACH compliant and tested for internal aspiration of combustible dusts/gases.
Temperature range: −25 to +65 °C.
