Hugely efficient, silently moves more air than another sub-ground fan, suits 300 mm diameter flexible duct. Mount the photo voltaic panel on any nearby sunny roof, or north-facing wall, and wire it immediately back to the fan.
For example, the place the sub-ground area has the lowest clearance from the ground to the floor an Envirofan single-brick sub-ground ventilation system would replace a vent underneath that particular space, whereby the extraction process the humidity is drawn out and replaced with recent air. This then ingresses by way of other present passive vents. This is where passive vents have their rightful place in constructing building, to act as an air consumption because of extraction by way of the Envirofan fan-pressured system. Only then will a passive vent reach its full potential.
More importantly, the followers only swap on when weather circumstances are proper. On damp overcast days, when the humidity is high, the fan doesn't operate, making them rather more environment friendly than previous-style electric fans on timers, which come on in all weather situations. All fans are rated for 50,000 hrs. Exopest can simply install Eco-pleasant, photo voltaic-powered or low-voltage 12v subfloor ventilation systems.
