PROTAPE® PUR 330 FOOD (LD)

Why this hose?

PROTAPE® PUR 330 FOOD (LD) is a versatile food hose covering broadly from pneumatics to medical technology. The light-duty (LD) construction is the middle weight in the FOOD-PROTAPE family — robust enough for daily pneumatics, flexible enough to move often.

The hose is tested and approved per all relevant categories in EU 10/2011 plus FDA 21 CFR 177.2600 and the German LFGB. The dimension range (Ø 25-450 mm) makes it suitable for smaller filling machines and large extraction systems alike.

Where it is used

In practice 330 FOOD (LD) is used in pneumatic conveyance of food powders, dairy and bakeries, and medical technology as a cable or air-supply hose.

The formal product name is PROTAPE® PUR 330 FOOD (LD). In daily use: "food-PROTAPE" or "330 FOOD".

Industries that use it

The hose is used across industries combining flexibility and food contact:

Food, pharma and medical technology use the hose for both pneumatic conveyance and as a cable/air-supply hose in hygiene environments.

Custom lengths and assemblies

The hose can be cut to length and assembled with couplings, cuffs and threaded fittings through Particulair's custom hose assemblies.

We offer guidance on material choice, coupling system and grounding, so the hose fits correctly into the overall system. If there is any doubt about zone classification or resistance requirements, a short conversation before ordering is well worth the time.

Frequently asked questions

What is the difference between 330 FOOD (LD) and 331 FOOD (XLD)?

330 FOOD (LD) is one class heavier than 331 FOOD (XLD). The wall thickness is higher, so the hose handles more mechanical wear. For daily pneumatics with grain, powder and granulates, 330 (LD) is the robust choice; 331 (XLD) is optimised for handling flexibility.

Is it also for medical technology?

Yes. The hose's food approval and PU construction make it suitable for cable protection and air supply in medical technology — wherever a flexible hose with clean materials is required.

Can the hose be supplied cut to length with couplings?

Yes. PROTAPE® PUR 330 FOOD (LD) can be cut to length and assembled with couplings, cuffs and threaded fittings through Particulair's custom hose assemblies. We provide guidance on coupling system and sealing so the hose fits correctly into the overall installation.

How do I order the hose, and where do you deliver?

The hose is ordered through Particulair (Karlslunde, Denmark). We deliver to Denmark, the EU and selected third countries such as Norway and Switzerland. Standard dimensions can typically be delivered in 1-2 weeks; custom assemblies and larger volumes require slightly longer lead time.

What is the hose's expected service life?

Service life depends on operating conditions: loading, temperature, chemical exposure, UV and mechanical movement. In standard industrial use, expected life is 3-7 years. Aggressive conditions (high temperatures, continuous flexing, chemical vapours) reduce service life. We recommend regular visual inspection for cracks, deformation or discolouration.

How is the hose best stored before use?

Store the hose dry, at room temperature (15-25 °C) and out of direct sunlight. Avoid contact with ozone-generating equipment (welding equipment, engines). If stored on a reel, the bend must be larger than the specified minimum radius to avoid permanent deformation. Proper storage significantly extends shelf life.

What is the minimum bend radius, and what happens if I go below it?

Minimum bend radius is the smallest radius the hose can be bent to without permanent deformation or internal damage. The table above shows specific values for each dimension. Bending the hose below this limit can collapse the wall, kink the spiral or damage the inner coating. The result is reduced flow, increased pressure loss and shorter service life. Always use bend radius as a design constraint in installation.

What do EU 10/2011 and EU 1935/2004 mean?

EU 1935/2004 is the framework regulation for materials and articles in contact with food — the overarching safety baseline. EU 10/2011 specifies plastics materials in food contact, including migration limits and test categories (A=aqueous, B=acidic, C=alcoholic, D=fatty, E=dry). When the hose is tested for relevant categories, it means it is safe for food contact with those media types.
