Fronius Exento HighVac Extraction System

The Fronius Exento HighVac Extraction System is designed for use with the Fronius Exento range of extraction welding torches, which incorporate the high-vacuum hose directly into the torch body for seamless source capture. It supports MIG/MAG, TIG, and MMA (manual metal arc) welding processes, making it a versatile solution for workshops running varied operations. The system is also compatible with the broader Fronius welding machine ecosystem, enabling automatic process-controlled extraction when paired with a compatible Fronius power source. If you are unsure whether the Exento HighVac will integrate with your specific torch or machine setup, our technical team at BWS are happy to advise — simply contact us before ordering.

Yes. The Fronius Exento HighVac is engineered to comply with EN ISO 21904, the international standard governing health and safety requirements for welding fume extraction equipment, as well as TRGS 528 — the German technical rule for welding fume that is widely adopted as a benchmark across European industry. Its H13 HEPA filter (certified to EN 1822) achieves a filtration efficiency of greater than 99.95%, making it suitable for capturing fine and ultra-fine carcinogenic particles including those generated when welding stainless steel, coated metals, and high-alloy materials. In the UK, where the HSE enforces strict occupational exposure limits for welding fume under COSHH regulations, the Exento HighVac provides a robust, auditable means of controlling welder exposure at source.

Filter service intervals on the Fronius Exento HighVac depend on the intensity of use, the welding process being performed, and the types of materials being welded — however, the system removes the guesswork entirely. Integrated differential pressure sensors continuously monitor filter loading, and when the filter approaches saturation, both a visual indicator light and an audible alert notify the operator that a filter change is required. This condition-based maintenance approach means you only replace the filter when necessary, avoiding premature replacement costs while ensuring extraction performance never degrades unnoticed. The filter change process itself is straightforward and tool-free, designed to minimise downtime on the shop floor. Replacement H13 HEPA filters are available through BWS, and our team can advise on stocking recommendations based on your typical workload.

The Fronius Exento HighVac can be operated as a standalone extraction unit and does not require a Fronius welding machine to function in its basic mode. When used independently, the extraction system can be switched on manually and will run continuously to provide fume capture at the source. However, the full benefit of the system's intelligent automatic control — where extraction power is activated and modulated in direct response to the welding arc — is achieved when the unit is connected to a compatible Fronius welding power source via the system interface. For workshops already running Fronius equipment, this integrated operation delivers optimal efficiency and hands-free performance. For those using third-party welding machines, the Exento HighVac still provides highly effective high-vacuum extraction in manual or continuous operating mode.
