Why this hose?
AIRDUC® PVC 341 (MD) is the classic PVC hose for daily industrial extraction. PVC is a more economical construction than PUR, covering broadly processes where mechanical wear and temperature are moderate.
The UL94-HB flame retardancy makes the hose suitable for processes where fire resistance is desirable — such as wood dust extraction or spray mist handling in non-classified zones. For ATEX zones, an AS or EC variant should be chosen instead.
Where it is used
In practice 341 (MD) is seen as standard extraction hose in industrial systems, and as flame-retardant ventilation hose in wood and surface treatment.
The formal product name is AIRDUC® PVC 341 (MD). In daily use: "the PVC extraction hose" or "341 MD".

Help with material selection
If you are choosing a hose and are uncertain about the right resistance level or zone classification, these two articles are a good place to start:
Industries that use it
The hose is used for daily industrial extraction across industries:
Plastics, wood and automotive industries use the hose as a standard extraction hose where flame retardancy is an advantage and ATEX is not mandatory.
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
Is it ATEX-approved?
No. PVC 341 (MD) is not antistatic and not ATEX-approved. For ATEX zones, choose an AS or EC variant from the AIRDUC® PUR family.
What is the difference between PVC and PUR?
PVC has lower temperature tolerance (+70 °C vs. +90 °C for PUR) and is generally less abrasion-resistant. On the other hand, PVC is more economical and fully suitable for daily extraction systems at standard temperatures.
Can the hose be supplied cut to length with couplings?
Yes. AIRDUC® PVC 341 (MD) 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 does UL94-HB classification mean?
UL94 is an American standard for plastics' fire response. HB ("Horizontal Burn") is the lowest flame retardancy class: the material burns at a limited rate on a horizontal specimen and self-extinguishes when the flame source is removed. This is sufficient for most industrial applications where fire resistance is desirable but not the primary safety layer. For stricter requirements, V0/V1/V2 classes are available (vertical burn test).
