120mm Fan Duct Cooling Shroud(10 Pack, No Clamps))(for Greenhouses, Enclosures, Crypto Mining, and More)(4 inch Vent Hose Adapter)

Excellent, works as intended to.. No complaints Included photos

I put a muffen fan on a plastic Rubbermade cabnet for 3D printing. This addapter fits perfect on 4" drier vent tube and the muffen fan. (Amazon Wathai 120mm x120 x 38mm 12V 2Pin Dual Ball with a small 12V wall addapter) The bolts that came with it fit though the muffen fan and back of cabnet, added washers inside cabnet. This blue addapter is made of good plastic and is not fragile at all, crank the tube clamps tight. The condo its in had no way out except a dyer vent. I teed the exaust into the dryer vent with with rest of parts from HomeDepot including plastic back flow preventers both on dryer and cabnet. Checking flow with tissue paper it worked great even with the dryer running and no disernable leeks.

Works good ordered 4” ducting and it wouldn’t fit over it. Not sure if I ordered the wrong kind or it’s made for something different.

I installed this on an ant miner s9 to vent heat outside my garage. It clamps well onto 4 inch flex dryer piping. I previously used a 3D printed one and the hose would constantly fall off and leak from warping. This is a solid piece of plastic with a lip and spring clamp, much better designed

The best made item for the job! Dont waste your money on the laser printed knock-offs. You will just damage your miners.

Useless without the clamps. Don’t trust the pictures. You will not get clamps or the black plugs. Why pay a premium for this when 1/2 of everything you see in the picture is not included? Build quality is average at best. Do yourself a favor and just buy the cheap plain black ones from somewhere else and save yourself a bunch of cash.

The ducting hardly fit and had to be forced on to the shroud. Also, the clamp hardly fits over the ducting and shroud. In fact, the clamp is not completely on all the way. The screws barely fit back with the shroud attached. In the end, I got it to work, but all components should just simply fit, without hesitation. However, this was not the case. I did not include the following information in determining my 3 star review. The information below is only to assist others that may be considering a 4 inch ducting solution for there Antminer. The temperature on my Antminer increased about 8-10 degrees even though the room is now much cooler since I’m exhausting the hot air out. I suspect the 4 inch ducting is too small and the hot air is backing up into the Antminer, and a bigger diameter ducting, for example 6 inch ducting, may alleviate this issue. I will try 6 inch shroud and ducting next - hopefully this will bring the Antminer temperature back down.

Does the trick, I use it to move the hot computer fan exhaust away from my desk. I also like how it came with hose clamps big plus.
