Not to be confused with vehicle ventilation, but I was looking to get rid of that very noisy bathroom fan in the place I bought, and came across these Panasonic WhisperValue DC ceiling or wall vents.
These are 120v AC powered fans but have a power supply that provides DC to the internal blower motor. Typical bathroom fans are very cheap 120v shaded-pole motors with a cheap, noisy, plastic agitator style fan. This high quality Panasonic fan uses a centrifugal blower, and it is smooth and quiet.
On the two lowest speeds, 50 and 80 CFM, it is barely audible. Set for 100 CFM, yeah, you can hear it but its not loud. It does seem to be very well made, and good quality.
I have no idea what the DC voltages are inside the unit, it might be interesting to tear into one but at about $95...nah...
