That fan array is top notch... I wouldn't change a thing about them... they look awesome and so far they have blown away the competition... lol I'd make the same thing for my own ventilation needs. I really like that controller you have for them.

First That fan assembly is beyond what I thought it could do. I was wrong. Second that has to be the first cage fan I've seen hit that watt with such low performance. I've seen some not worth putting in cars and others not large in size nearly blow a guy over. But all well under 800w. Third I might try this but go the other route. Replace the cage fan on a central unit. Considering it's half the operation cost. You may of just tripped over something and again I was wrong. Last If the cage is the reason for it's low performance. A motor change will not change the pressure draw enough to matter. Just lower the watt cost. This Vid definitely has me scratching my head. Well done.

That furnace blower moves good air when it’s sitting by itself, it just massively drops when it’s restricted. I think I’ll have to measure shaft rpm after the motor swap just to double check, but it doesn’t have me too optimistic. I could try another blower assembly, this one looks good and spins quite smooth, but maybe something is going on.

I was not at all expecting that, I think I dropped a comment about a squirrel cage on your prior video. Okay, I am convinced, thanks for doing the work and documenting it! What are the small fans again?

It performed shockingly poorly, so I think I need to try with an ECM motor. It shouldn't change airflow much, but it should cut power down. The fans are Sanyo 9GV1212P1J091. There's a few options that are similar, these are some of the best 120mm fans for moderate airflow and pressure.

That’s a bummer, I have two of these and had thought about using them in summer for heat control. Guess not. Efficiency is everything here because of the high power costs. Thanks for the great video.

I think the louver right next to the exit on the blower is a big issue for this assembly. The pressure gauge is only showing the depressurization of the building, which is what matters for airflow, but is not the total pressure the fan is exposed to. Still, I would have expected a lot better performance from this blower...

Sorry to disappoint you but, those little fans are designed to move air for short distances like over a computer processor. If you replace the furnace motor with those little fans in the same set up as the furnace fan you will get very little to no air coming out of the vents outlets and into the returns inlets in a house setup. Any HAVC equipment manufacturer will confirm this.

@@jaimeparadise I’m a bit confused then. The data suggests that furnace blower isn’t performing as well as a little fan. Are you suggesting the testing is invalid? The difference between the two is so absurd I find it hard to believe the data is off by that much.

@@SiCPoWMining Your "DATA" is not for the correct application. Yes those computer fans use less watts than the Hvac fan but do not move the air far enough, you are not considering blade design. If you install those fans in regular hvac application you will get no air coming out of the air vents. (the grills you see on the ceiling where air comes out of). That "wheel" has been discovered long time ago. Don't waste your time and others as well.

@@jaimeparadise …What? I never suggested installing axial fans in a furnace. I told people specifically not to make fan arrays like mine. Are you suggesting this video is telling people to replace furnace blowers with 120mm computer fans? The application is exactly what I’m measuring. Airflow through THIS room is the sole intent and function for this fan. It has absolutely nothing whatsoever to do with a furnace.

could maybe affix a filter somehow to the intake of the a/c fan.. man those fans move some crazy amount of air but have to be careful cause if you dont have enough air from intake.. it could starve the motor and overheat.. and then.. fire that why these are usually found either outside in a unit.. or with a filtered direct flow from outside.. and with those fans.. you have to have a duct for it to build pressure.. thats where and how it builds so much airflow cant just put it in the window... take it by itself on the floor.. and cover some of the exhaust of the fan.. youl see the fan ramps up and airflow goes way up too and youll have more airflow.. at lower speeds and lower power
