NORRES PROTAPE® PUR 330 AS BLACK (LD)
Antistatic black PUR hose for dust, gas and process extraction
NORRES PROTAPE® PUR 330 AS BLACK (LD) is a lightweight, reinforced and antistatic polyurethane hose designed for the transport and extraction of gases, dust, fibres and powders in explosive or industrial environments. The black colour protects against light and provides a robust exterior, ideal for installations and machinery where transparency is not required.
Performance and applications
The hose is used in process and ventilation systems, filter and extraction units, surface treatment equipment, blasting systems and dust collection machines. It is resistant to oil, fuel and chemicals and remains highly flexible at low temperatures (down to −40 °C).
Antistatic according to ISO 8031 and TRGS 727 with electrical resistance < 10⁹ Ω. Suitable for ATEX zone 22 (dust inside) and zones 1/2 (gases and liquids).
Temperature range: −40 °C to +90 °C (short-term +125 °C).
Certifications and construction
PROTAPE® PUR 330 AS BLACK (LD) is a tape hose with built-in spring steel wire (1), antistatic PUR wall (2) and an abrasion-resistant outer layer (3) made of premium ester-based polyurethane (Pre-PUR®).
Complies with ATEX 2014/34/EU, TRGS 727, RoHS, REACH and ISO 8031.
Available in multiple diameters and lengths, also with optional customised colour or logo printing.
