WDH fans comply with the EU energy efficiency requirements for fans and ventilation systems.  These fans are characterised by high performance, optimum airflow rates and more options for adjusting airflow and operating noise levels according to current needs.
WDH fans with horizontal discharge are designed for use in locations where continuous mechanical ventilation is required, e.g. production halls, warehouses, retail centres, shops, offices, etc.
The extracted stale air may contain corrosive vapours, gases and particles within the limits set by environmental regulations.
