Why this hose?

AIRDUC® PUR-INOX 350 FOOD-AS has a food-grade, permanently antistatic Pre-PUR® wall and a stainless steel spiral. It is highly abrasion-resistant and suited to conveying food and pharmaceuticals.

The manufacturer states a normal temperature range from −40 to +90°C and short-term up to +125°C.

Important context

The hose is one part of a system. The antistatic property only works when the whole system is correctly grounded.

Where it is used

The manufacturer lists conveying food and pharmaceuticals.

The formal name is AIRDUC® PUR-INOX 350 FOOD-AS.

Overpressure and underpressure values are recommended operating limits; the product can be subjected to higher loads on request. Bend radius is measured along the inside of the hose bend.

Standards and compliance

The manufacturer documents the following:

Food contact. The wall complies with EU 10/2011, EC 1935/2004 and EU 2015/174 as well as FDA 21 CFR 177.2600.
GMP (EC 2023/2006). Good manufacturing practice for materials in contact with food.
Permanently antistatic wall. Electrical and surface resistance below 10⁹ Ω according to ISO 8031 (below 2.5·10⁸ Ω·m according to TRGS 727, 10⁸–10⁹ Ω according to NFPA 652).
DIN 26057 type 2.
REACH (EC 1907/2006) and RoHS 2011/65/EU. The manufacturer holds declarations of compliance.

A hose is not itself ATEX certified. It must always be grounded, and whether it suits a zone is decided in your own zone assessment.

Frequently asked questions

Which food approvals does the hose have?

The manufacturer states that the wall complies with EU 10/2011, EC 1935/2004, EU 2015/174 and FDA 21 CFR 177.2600, and that manufacturing follows GMP, EC 2023/2006.

Can the hose be used in explosion hazard areas?

The manufacturer states a permanently antistatic wall according to ISO 8031 below 10⁹ Ω. A hose is not itself ATEX certified. It must always be grounded, and whether it suits a given zone is decided in your own zone assessment.
