Pax 900 backdraught shutter

For retrofitting on Pax 900

In order to avoid air moving in the wrong direction when installing fans in ducts without natural ventilation (e.g. through an external wall), a backdraught shutter can be installed. A requirement for this is that another ventilation system must manage the basic ventilation flow of the building. Note: A backdraught shutter has a negative effect if the fan is installed in a ventilation duct with natural ventilation.
