WDVO roof fans

WDVO roof fans
WDVO fans comply with the EU energy efficiency requirements for fans and ventilation systems. They are high-performance fans with excellent air efficiency as well as enhanced noise level control and air flow adjustability according to current needs.
WDVO fans with horizontal airflow are designed for use in locations where continuous mechanical ventilation is required, e.g. in production halls, warehouses, retail centres, shops, offices, etc.
The concentrations of corrosive vapours and gases or particulates in the exhaust air should not exceed the acceptable limits specified by environmental regulations.
