Is the Hose for powders, dust PARAFLEXÂ® suitable for positive pressure applications or only for vacuum (up to 0.6 bar)?

Hose for powders, dust PARAFLEXÂ® Format is intended only for vacuum (extraction) applications . it is not designed for positive pressure. The product description explicitly states resistance to vacuum up to 0.6 bar and specifies that it is "Not intended for use with positive pressure," so do not use it under positive-pressure conditions.

Can Hose for powders, dust PARAFLEXÂ® be used in outdoor environments exposed to UV and harsh weather conditions?

Hose for powders, dust PARAFLEXÂ® is suitable for outdoor use: the outer corrugated SBR rubber layer is weather- and abrasion-resistant and the hose operates from -40Â°C to +70Â°C, making it capable of withstanding UV and harsh weather conditions typically encountered outdoors. Note that it is designed only for vacuum (extraction) up to 0.6 bar, includes a copper anti-static wire, and is not intended for positive-pressure applications.

Can Hose for powders, dust PARAFLEXÂ® be used with electrically conductive materials without additional grounding?

Hose for powders, dust PARAFLEXÂ® includes a copper anti-static wire for discharging electric charges, which reduces the risk of electrostatic buildup during conveyance of powders and dusts. However, the presence of an anti-static wire does not automatically eliminate the need for additional grounding in all installations. If the transported material or the process can generate significant electrostatic charges, applicable safety standards or site electrical codes typically require that the anti-static wire be firmly connected to a true earth ground at regular intervals and at both ends of the hose assembly. For safe operation with electrically conductive or potentially charge-generating materials, you should: - Verify that the hoseâs anti-static wire is continuous and electrically connected to any metal fittings. - Ensure the anti-static wire is properly bonded to plant earth ground on installation. - Follow local regulations and industry standards for electrostatic discharge (e.g., ATEX, NFPA) that apply to your facility and materials. - Inspect connections and continuity regularly as part of maintenance. In summary: Hose for powders, dust PARAFLEXÂ® is equipped with a copper anti-static wire to discharge charges, but you must provide proper grounding (bonding to earth) according to standards and site requirements; do not rely solely on the hose without verified grounding.

Very lightweight and extremely flexible rubber hose for dust extraction, powders, and other lightly abrasive materials. The inner layer is smooth, made of wear-resistant rubber with a thickness of 2.4 mm. The outer layer is corrugated, resistant to abrasion and weather conditions. Thanks to the steel spiral reinforcement, it is resistant to kinking and vacuum up to 0.6 bar. Not intended for use with positive pressure, designed only for vacuum (extraction). Due to its lightness and exceptional flexibility for a rubber hose, it performs excellently in vacuum cleaning systems in the industry, such as in quarries or foundries. It features a copper anti-static wire for discharging electric charges. Inner layer: black natural rubber. Reinforcement: synthetic cord, steel spiral. Outer layer: black SBR rubber. Vacuum: up to 0.6 bar. Operating temperature: from -40°C to +70°C.
