Why this hose?
AIRFLEX® 4500 is a highly flexible and kink-resistant suction hose in soft PVC. The rigid PVC spiral keeps the hose open, and the corrugated outer cover makes it easy to bend.
The hose is highly abrasion-resistant, has good chemical resistance and is microbe-resistant. It comes in 23 sizes from 20 to 305 mm.
Where it is used
The hose is used on extraction units for waste gas, chemical vapours and dust, and in ventilation and air conditioning.
It is also used for air supply, condensate drainage and as cable protection.
In everyday talk we call it a suction hose or ventilation hose.

Help with material selection
Although this hose isn't ATEX-relevant, these two articles provide useful background on electrical resistance and industrial safety — important if you later combine the hose with electrical equipment or work in mixed environments:
The invisible weakest link
Why a conductive or antistatic hose isn't sufficient on its own — and what grounding means for the complete system.
Know your ohm
The difference between antistatic and conductive, which resistance limits apply where, and how to measure them correctly.
Industries that use it
AIRFLEX® 4500 is used in:
The chemical industry, extraction and filtration technology and HVAC, where air, gas, smoke and dust are extracted or ventilated.
Custom lengths and assemblies
The hose comes in 10, 20, 30 or 50 m depending on the diameter. We cut it to length and fit clamp fittings as a finished assembly.
Frequently asked questions
Which media is it intended for?
Air, gas, smoke and dust. It is also used for condensate drainage and as cable protection.
How much vacuum does it withstand?
It depends on the diameter: from 0.6 bar at 20 mm to 0.1 bar at 305 mm. See the dimension table.
Is it ATEX-approved?
No. There is no ATEX documentation for the hose.
How is it assembled?
With clamp fittings. We cut the hose to length and can supply it as a finished assembly.
