Are these approved or do they work on high velocity airflow?

I don't know if any vendors have approved them, but the contractor that sold and installed my Trane high-velocity system said they're okay to use. I recommend checking it at least once a month to make sure it's not clogged up, and don't buy ones that are higher than 300 unless you don't mind having to replace them as frequently as every three weeks.

I don't know the max RPM for the stock fans (I didn't even use them; swapped them out with Excaliburs), but I know that they are 3pin (they do not come with a molex adaptor, so you'll need to buy those separately if you don't want to hook them up to your MB or fan controller).

I have found out that they were a direct fit for my 89. the flow matched. I have only about a 100 miles on the car since I did replace them and I cant give you a long term evaluation of them.I did have a lot more power. I would recommend them

If the information states it will work with fans, then it's ok. I have never used them with fans, but I can see how they will work ok.

You're asking two questions Dimitri. They will move more air than your stock H80 fans, but if you run them at full speed all the time, which is recommended, then quiet is not going to happen. They are not loud, but you know they are on all the time. These took 6C off the stock fans on my H60, so they definitely made a difference. I am more concerned about having my 8350 CPU being cool. I can live with the hum of the fans.

You are pretty accurate, I love these fans because they move LOTS of air and I have been running it 24/7 for four months now with no problems. The negatives, they are loud and as you said there is not a significant difference between speeds; there IS a difference, but not from a quiet whisper to full throttle.

Not sure of your question. I have installed only mine per instructions and do get some wind noise at higher speeds. I don't leave them on car unless I'm hauling my ski box.

The filters (2) are proprietary and only available from Trend. They are high quality foam type filters but I don't think they are hepa rated.I use the Airshield for woodturning and find it to be very effective for air filtration and face protection.

I do think they will work, but make sure the air gun has a dovetail on top of the barrel.

Yes they will work. I currently have a Hyper 212 Evo and they fit just fine with plenty of clearance.

No reason you can't just let it hang off in space somewhere. I just put mine in a quite unusual place that is out of the way and works beautifully. Better airflow intake that way. Think outside the box and it's less important. To answer the question, I would guess 90% likely the generic will work.

It all depends on what type it is, these are only vented on the cap. If it's a case where air can move around they'll probably do fine

It works well for mine, in fact I use a Variac to slow the speed down as it's almost too much air flow.

You can make it work but you'd have to jet it and have a full exhaust to make it run right. Youre better off getting a hi flow drop in with a modified airbox lid(remove it)and do the same mods. It'll be more reliable and the performance gain will be the same. Coincidentally, you can't remove the lid without re-jetting your carbs for the extra flow.

These filters fit the home brew models, such as yours. These are the Bunn brand. They fit perfectly in my Velocity Model.

Yes there are many mods and bulk air adapters. hpa, nitrogen and co2 are all compatible. Drozdmax.com is a great site.

I've only used it in grain dust but I think they are the same filters my other friends use when hauling anhydrous ammonia. They should be dot approved.
