When milling and grinding dental materials, dental laboratories produce fine dusts that not only pose a health risk but can also impair technical equipment. Renfert's new SILENT flow sensor brings a breath of fresh air to the discussion about occupational safety - and ensures clear conditions at the workplace.

Why clean air is more than just comfort

Although fine dust in the air is invisible, it is dangerous.  Exposure to milling and grinding dust is particularly high in dental laboratories, where plaster, acrylics, ceramics and metal alloys are used on a daily basis. These particles can:

  • irritate the respiratory tract and cause long-term damage,
  • accumulate on sensitive sensors and equipment,
  • impair the performance of machines.

The solution? An intelligent sensor monitoring the suction power of the suction unit and giving an immediate acoustic and visual warning if the suction power falls below a critical level.

The challenge: Recognizing invisible dangers

Despite powerful workbench extraction units, there may be performance losses - whether due to clogged filters, technical defects or unnoticed impairment of the suction power. Without monitoring, the risk often remains undetected. This is precisely where the SILENT flow sensor comes in.

The solution: Intelligent monitoring with a signal effect

The SILENT flow sensor is easily mounted on existing workbench extraction systems from Renfert and it continuously monitors the volume flow. If the suction power falls below a defined threshold value, the sensor emits a visual and acoustic alarm. Users can react immediately and avoid health risks.

Key benefits at a glance:

  • Easy retrofitting: Compatible with all SILENT workbench extraction units from Renfert.
  • Intuitive warning signals: Immediate acoustic and visual notification in the event of a drop in performance.
  • Maintenance-friendly: Easy to clean and built to last.

Sophisticated technology for greater safety

The SILENT flow sensor is more than just an accessory - it is an active contribution to health protection. By precisely monitoring the suction power, it detects potential hazards at an early stage.

Conclusion: Small investment, big impact

Renfert's SILENT flow sensor demonstrates how modern technology can enhance work safety and comfort in dental laboratories. The most important advantages at a glance:

  • Active support for health protection - thanks to a timely warning of hazardous dusts.
  • Equipment remains operational - as sensitive components are protected from dust deposits.
  • Easy integration - uncomplicated retrofitting and intuitive operation.
