Ventilation Systems

The Challenge

  • Inconsistent airflow → gas accumulation & heat stress pockets
  • Energy waste from poorly balanced fans & leakage
  • Non-fire-safe barriers increase risk during incidents
  • Slow manual adjustments; no feedback or alarms
  • Long lead times for spares and custom sizes

Our Approach

Avux designs, manufactures, and integrates ventilation systems end-to-end: LSZH seals, ducts, doors, and sensor-driven control. We instrument your airways, feed PLC/SCADA and automate fan set-points to maintain targets while cutting energy loss. Local manufacture and regional support reduce downtime.

  • Fire-safe barriers
  • Smart airflow control
  • Local manufacture & support
