The regular blower moves 1K cubic feet per minute (cfm). Let's calculate. If it runs every minute of the day, that would be: 24h consists of 1,440 min.
The daily volume that a 1K cfm blower moves is 1.44M cfm.
Now to understand the weight of the number we need to know the density of air which as you guessed varies. It changes depending on the location on the planet. height above, or below the sea level, local temperatures and level of humidity.
For the calculation, we took the number of an average density - 0.075 pounds per cubic foot. Daily weight is 0.075*1.44M = 108K pounds per day
Let's convert to tons: 108K/2K = 54 tons per day
1. If a blower runs 24h, you're probably wasting energy and turning a house into a dusty or mouldy factory.
2. If it runs 12h a day, the result is 27 tons of air per day.
3. Even if it runs 6h per day, the blower will still be moving over 13 tons of air.
