EVA 373 AS
Highly flexible suction hose in ethylene-vinyl acetate (EVA), antistatic and chemical-resistant. Crush-resistant construction means the hose withstands collapse under vacuum better than standard suction hoses. ATEX-approved for Zone 22 dust and Zone 0/1/2 gases. The classic choice on industrial vacuum cleaners, floor cleaning machines and swimming pool cleaning systems where light weight and flexibility are central.
- Static dissipation <10⁹ Ω
- Zone 0/1/2 + 22
- Chemical-resistant EVA
- Crush-resistant suction hose
- Gas, dust
- Cut to length
Why this hose?
EVA 373 AS is the classic suction hose you find on an industrial vacuum cleaner or a floor cleaning machine. The EVA material is chosen for exactly this application: flexible, chemical-resistant to many solvents, and light enough that an operator can pull the hose around for hours without fatigue.
The antistatic wall with surface resistance below 10⁹ Ω meets the TRGS 727 and NFPA 652 thresholds, and the hose is ATEX-approved for Zone 0/1/2 (gases) and Zone 22 (dust, interior). The broad zone coverage is worth highlighting — many standard antistatic hoses cover only Zone 22, but EVA 373 AS also covers the most restrictive Zone 0 gases.
Crush-resistant construction is a tangible advantage in high vacuum. On standard suction hoses, vacuum can pull the walls together and block flow — the classic "suction hose collapse". EVA 373 AS is built specifically to resist this, making it a reliable daily working hose on industrial vacuum cleaners and cleaning machines.
Lower temperature tolerance than PUR. EVA 373 AS is rated for +65 °C, lower than the PUR hoses' +90 °C. If the process involves hot media or hot environments, choose a PUR- or TPE-based hose instead.
Where it is used
EVA 373 AS is built for industrial vacuum cleaners and cleaning machines. It is the hose that typically comes from the manufacturer on a facility-grade industrial vacuum cleaner, and the classic choice when an existing hose needs replacement.
In practice we see it used on floor cleaning machines in industrial and institutional environments, on pool cleaning equipment where light weight and chemical resistance are central, and for spill response where mobile vacuum cleaners need to reach further.
It is also used for cleaning in classified zones (Zone 22) where an antistatic wall is mandatory, and as a light extraction hose in smaller fixed installations.
The formal product name is EVA 373 AS. In daily use, many simply call it "the light AS hose" or "the vacuum cleaner hose" — the classic choice on industrial vacuum cleaners and cleaning machines.

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 hose is certified or documented to the following standards:
- ATEX 2014/34/EU (1999/92/EC). The directive for equipment and protective systems intended for use in potentially explosive atmospheres. The hose is approved for zone 0/1/2 (gases) and zone 22 (dust, interior).
- TRGS 727. The German technical rules framework for combustible dust and static electricity.
- ISO 8031. Measurement of electrical resistance in rubber and plastics hoses.
- REACH (EC 1907/2006) and RoHS 2011/65/EU. The manufacturer holds declarations of compliance.

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 across industries where light-weight vacuum handling combines with an antistatic wall:
Cleaning and cleaning-machine industries use the hose as a standard choice on industrial vacuum cleaners and floor cleaning machines.
Machinery and institutional environments use it for daily cleaning in classified areas where antistatic wall and crush resistance are combined priorities.
Pool, spa and leisure industries use it for pool cleaning equipment where chemical resistance and flexibility are central.
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 EVA material?
EVA stands for Ethylene-Vinyl Acetate, a thermoplastic copolymer. It is flexible, chemical-resistant against many solvents, and crush-resistant — better at withstanding collapse under vacuum than PUR. On the other hand, EVA is less abrasion-resistant than PUR and has lower temperature tolerance (+65 °C vs. +90 °C).
Can the hose be used in Zone 0?
Yes. EVA 373 AS is ATEX-approved for Zone 0 (gases, interior), Zone 1 and 2 (gases), and Zone 22 (dust, interior). That is a broader ATEX approval than many standard antistatic hoses. Proper grounding is a prerequisite.
What temperature range does the hose tolerate?
The normal operating range is −25 °C to +65 °C. That is lower than the PUR hoses (+90 °C), so EVA 373 AS is primarily intended for indoor cleaning applications rather than industrial high-temperature processes.
What does "crush-resistant" mean?
Crush-resistant means the hose is built with combined reinforcement and spiralling that resists collapse under high vacuum. On a normal suction hose, vacuum can pull the walls together and block flow — crush-resistant constructions are specifically designed to avoid this on cleaning machines with high vacuum.
Can the hose be supplied cut to length with couplings?
Yes. EVA 373 AS 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.
