HUPLONG INDUSTRIES (M) SDN BHD is the authorized distributor of NORRES industrial hoses in Malaysia.

HUPLONG INDUSTRIES (M) SDN BHD supplies genuine NORRES AIRDUC® PUR 350 AS BLACK (MD) medium-heavy antistatic polyurethane hoses for flexible ducting of abrasive powder, bulk material, granulate and gases.

NORRES AIRDUC® PUR 350 AS BLACK (MD) is an antistatic polyurethane hose in the medium-heavy duty classification. The official NORRES design is an AIRDUC® profile hose with a spring steel wire firmly embedded in the wall. The hose wall is permanently antistatic premium ester-polyurethane Pre-PUR® with an approximate wall thickness of 0.7 mm.

NORRES states that this model is highly abrasion resistant, has good resistance to oil, gasoline and chemicals, and provides very good low-temperature flexibility. NORRES also lists this model according to DIN 26057 Type 2.

The permanently antistatic wall is specified according to ISO 8031 with electrical and surface resistance below 10⁹ Ω. NORRES also states a value below 2.5 × 10⁸ Ω*m according to TRGS 727 and 10⁸ to 10⁹ Ω according to NFPA 652.

NORRES states that AIRDUC® PUR 350 AS BLACK (MD) is in accordance with ATEX 2014/34/EU (1999/92/EC) and German TRGS 727 for the officially listed pneumatic transport of flammable dusts and bulk materials in Zones 20, 21 and 22 inside; aspiration of combustible dusts in Zone 22 inside; conveying of flammable liquids in Zones 0, 1 and 2 inside; conveying of non-flammable liquids; use in Zones 1 and 2 for gases; and use in Zone 0 for gases.

Official NORRES applications include air supply for UV dryers and IR dryers, extraction units, dedusting systems, filter systems, oil mist extraction, textile fibre extraction, clean-room ventilation, semiconductor production machines, heating hose protection applications, and surface-preparation systems including shot blasting and sand blasting recovery.

The official operating temperature range is -40°C to 90°C, with short-time operation up to 125°C. NORRES lists black as the standard delivery variant. Further diameters and lengths, special full-coloured versions and customer-specific branding are available on request according to NORRES.

NORRES states that AIRDUC® PUR 350 AS BLACK (MD) conforms to the RoHS guideline.

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.

The permitted pressure, vacuum and bending-radius values vary by hose size and must be checked against the official technical table before use.
