Is the Hose for contaminated air, dust, dust FLEXOCOND safe for use in ATEX zones and what grounding measures are required?

Hose for contaminated air, dust, dust FLEXOCOND Format: Yes . but with conditions. The hose is made of conductive polyethylene (PE) and elastomer with low material resistance and is designed to avoid accumulation of electrostatic charges. Models DN38 and DN50 have a declaration of conformity with ATEX and TRGS 727 and therefore may be used in explosion-hazard (ATEX) zones provided safety measures are met. Required grounding measures and conditions: - Effective grounding is mandatory: hose must be permanently and reliably connected to protective earth to dissipate charges. Use conductive fittings or clamps that ensure low-resistance electrical continuity along the hose to earth. - Use conductive fittings compatible with the hose spiral (left-handed where applicable) or approved conductive connectors; plastic fittings are acceptable only if they provide certified conductive path. - Verify continuity after installation (measure resistance between hose and earth). Maintain resistance below the limit required by site standards/ATEX guidance (consult local rules; typical practice requires â¤10^6 ohm for antistatic hoses, but confirm per employer/authority). - Conduct a site-specific risk analysis by the user/operator before use in ATEX zones, addressing dust type, particle concentration, ignition sources, bonding of connected equipment, and operational procedures. - Ensure proper maintenance: inspect grounding connections, hose integrity, and fittings regularly; avoid insulating contaminations or damage that could break the conductive path. - Respect operating temperature limits (â20Â°C to +60Â°C) and the specified vacuum ratings. Summary: DN38 and DN50 FLEXOCOND can be used in ATEX zones if the hose is effectively grounded with conductive fittings/clamps, electrical continuity is verified, and a user-conducted risk analysis is completed.

Can Hose for contaminated air, dust, dust FLEXOCOND withstand temperatures from -20Â°C to +60Â°C during continuous operation?

Yes. Hose for contaminated air, dust, dust FLEXOCOND can withstand continuous operation temperatures from -20Â°C to +60Â°C. Note that operating vacuum depends on temperature. For safe use where electrostatic charge may occur, the hose must be effectively grounded. DN38 and DN50 sizes also have ATEX/TRGS 727 conformity for explosive atmospheres when grounded and after a user-conducted risk analysis.

How should Hose for contaminated air, dust, dust FLEXOCOND be cleaned and disinfected without damaging conductivity?

Hose for contaminated air, dust, dust FLEXOCOND should be cleaned and disinfected in a way that preserves its electrical conductivity and does not damage the polyethylene/elastomer construction or the embedded conductive spiral. Recommended procedure: 1. Disconnect and ground - Before any cleaning, disconnect the hose from equipment and ensure the hose and cleaning personnel are properly grounded to avoid static buildup. 2. Dry removal of bulk contaminants - Remove loose dust and debris using low-pressure compressed air (max. 2â3 bar) blown from the clean end toward the contaminated end, or by gentle brushing with a soft, non-metallic brush. Avoid metal tools that could scrape the conductive spiral. 3. Vacuum-assisted cleaning - Use an industrial vacuum (with conductive fittings and grounded suction) to extract remaining particles. Ensure the vacuum system is compatible with conductive hoses and explosion-risk protocols where applicable. 4. Wet cleaning and disinfection (if required) - Use lukewarm water (not exceeding +60Â°C) with a mild, non-ionic detergent. Apply with soft cloths or low-abrasion sponges; do not use solvents, strong acids, alkalis, or chlorinated solvents that can degrade polyethylene/elastomer or affect conductivity. - For disinfection, choose aqueous, non-corrosive disinfectants compatible with PE/elastomer (e.g., diluted alcohol-based or quaternary ammonium compounds approved for plastics). Follow manufacturer dilution and contact-time instructions. - Rinse thoroughly with clean water to remove detergent/disinfectant residues. 5. Drying - Dry the hose completely before reuse. Use ambient air drying or warm air (<60Â°C). Avoid high-temperature drying or direct heat sources that exceed the hose operating temperature. 6. Inspection and testing - Visually inspect for cuts, abrasions, or chemical damage, especially near the external spiral. Check that fittings/clamps are intact and that conductive continuity to ground is maintained (measure resistance as required by your safety procedures). - Re-establish grounding and verify conductivity before returning the hose to service, particularly in ATEX/zone applications. Warnings - Do not autoclave or use aggressive solvents or abrasive cleaning that can damage the material or spiral. - Always follow site-specific risk assessments and ATEX/TRGS 727 requirements when used in explosive atmospheres. Following these steps preserves Hose for contaminated air, dust, dust FLEXOCONDâs conductive properties and service life.

Additional information

Material	PE – polyethylene
Maximum operating temperature [°C]	60
Minimum operating temperature [°C]	-20
Vacuum resistance	yes
Standard length [m]	30
Reinforcement	reinforcing spiral shaped in the profile of a hose

Very lightweight, flexible, wrinkle-resistant hose designed for the transport of air, smoke, fiber dust, dirt, and other lightweight substances. Used in industrial vacuum cleaners. Made of conductive polyethylene (PE) and elastomer, with low material resistance, excellent for applications where the accumulation of electric charges must be avoided (the hose must be effectively grounded). The external reinforcing spiral shaped in the hose profile, left-handed, allows for the attachment of appropriate fittings for vacuum cleaners with left-threaded connections, e.g., plastic fittings for EVA hose: DN32, 38, and 50 or suitable conductive fittings. Hose installation is also possible using clamps on appropriate ends, pipe fittings, etc. The hose with diameters DN38 and DN50 has a declaration of conformity with ATEX requirements and TRGS 727 standards and can be used in explosion hazard zones, provided the hose is effectively grounded and a risk analysis is conducted by the user. Hose material: black special polyethylene (PE) and elastomer. Reinforcement: reinforcing spiral shaped in the hose material. Operating temperature: from -20°C to +60°C (operating vacuum depends on temperature).
