Meet
Mr. Blowerᵀᴹ
He's a rescue, from a junkpile at an area HVAC company. It's a blower or, "air handler" out of a residential central heating and air unit. Quite common actually. This one looks to be only a few years old. This is how these companies make their piles of cash - they get called out for a simple problem then they start hard selling a totally new system instead of just fixing the problem. Ignorant homeowner is out 6 grand for a problem they could have fixed for a service call and a part. The company takes their existing equipment and tosses it into a junkpile, to be scrapped later. Anyway, the motor on this blower is totally good, not any problem at all with it, its bearings, or any problem with the blower wheel itself. It was going to the scrapyard anyway, so I liberated it and re-purposed it.
I used the finger guard from an old fan I had laying around to cat-proof it, then built the little wooden frame to snugly fit one of my smaller windows, screwed it to the sheet metal of the blower then came up with a clever mounting scheme.
This mother fucker is moving 4000 CFM and that is some serious volume. It takes the air from outta my house and blows it out the window. I open a greater or equal size window on the opposite end of the house from it and let 'er rip. My house holds about 12,000 cubic feet of air so with this
I am changing out the air in the house every three minutes.
This keeps me from hardly ever having to run my AC in summer. In late fall or early winter, it keeps the house from getting stuffy and too warm. The weather here is typically mild enough to want that power-ventilation. Plus I always have fresh air breezing through when this badass is running - AND it uses two-thirds LESS power than either my AC or heater!
If it's too cold or hot out of course, Mr. Blower rests on the floor of my little workshop I have in the house.
Anyhow, greet him! Tell him how good he looks! I was gonna name him "Billy Badass" but wanted to give him more respect. He saves me money and keeps the air in my house outdoor-fresh!
Ain't none of you wombat-faced twits got anything like this.
