Nehmo -
I have not done any of the math regarding how large the pressurizing fan
should be or what pressure should be achieved. But a rough estimate is
possible: To simplify the problem, let's say the house has no vents, no
plumbing fixtures, no gas appliances, and the house is of an almost
airtight modern construction. I often use a 6.5 amp (120 Volts) shop
vac and get respectable results. I imagine using an 11 amp fan (I've
one) as the pressuring means would get reasonable results at the
pick-up tube.
The next step in something like this is to experiment a bit.

Airline cabin pressure can go as low as 75% one atmosphere or
equivalant to an altitude of 8,000 feet.

The fact is not relevant. I just found it while looking around and I
thought I would share it:-)
