Inside a positive input ventilator
🕑 Added 2025-04-07 21:03:57 +0000 UTCThis monster of a device is basically just a quiet low powered fan that pushes air from your attic into your home. It slowly displaces humid and musty air to keep your home fresh.
This isn't a full reverse engineer, due to the very firm connections that risked damaging the PCBs if removed. I was also planning on installing the thing before the weekend live stream, so I took the images and then reassembled and fitted the unit.

I don't think I'd like all the yucky stuff from my ceiling cavity coming into my house. Older houses have bird droppings, rat droppings, heaps of dust and glass insulation dust. No thanks. I'd rather go with a heat exchanger (I built one and installed it and it ran for over a decade when I sold the house) that vents directly outside.

Interesting. In The Netherlands a lot of houses (build somewhere from the seventies till the zeroes - guestimating here) have central or mechanical ventilation. It's similar, but the unit sucks air from (usually) kitchen/living room and bathroom and blows it out through a chimney or outlet. The air is replaced by outside air, coming from natural gaps and cracks.
