7" inch Universal Slim Fan Push Pull Electric Radiator Cooling 12V Mount Kit Black

Nice little fan with a lot of output. Works great as a cooling fan for my Chinese muni excavator. Not too noisy, but its not whisper quiet. You will hear it, if that's your concern. Comes with several mounting options

This generic radiator fan is a great value replacement! It installed easily, fit my application well, and immediately restored proper engine cooling. It moves a surprising amount of air and is just as effective as the original part, but at a fraction of the cost

I use my machine in continuous mode, for hours with only short breaks. The Rato 740 / Predator 670 starts overheating if nothing is done about the heat being dumped into the center compartment by both the hydraulics and the motor. The hot interior air circulates around and is sucked up by the motor and the ignition coils (and who knows what else) starts to overheat. These fans can be mounted in the sides to exhaust that hot air. Wire them in parallel with the hydraulics fan. If that fan is automatically switched, it would probably be a good idea to install a relay so the thermostatic switch isn't handling the 15-20 amps. Even if you are using a manual switch, make sure it is one that can handle that many amps continuously, or better yet, install a relay. I have installed one, and the overheating problem is nearly solved. The regulator output voltage dropped only about 0.1V with the added load, so a second one is being installed. If you have the smaller (420) engine, one may be all you need. For the 740 / 670, two seems necessary on even a mild (mid-70s) day. Also, make sure your hydraulic cooling fan is configured correctly. Mine was spinning in the correct direction but the blades had not been turned around, so it was not moving much air (and consuming too much power). The blades are stamped with direction of rotation; also look at the curvature of the blades. Same holds true for this fan; to set up in push mode, you have to reverse the wiring AND flip the blade so it is spinning in the correct direction. I also replaced the machine's side panels with hardware cloth, to better allow air flow. If you do not run your machine continuously, this all is probably not an issue. But if you are running it more than about an hour at a stretch, compartment ventilation is highly recommended.

Used ot to replace the fan In my BMW K75RT. OEM is hard to find and expensive, took a bit of engineering but it works fine. Not too noisey.

moves a lot of air for such a small fan, it keeps my $9,000 firepunk race trans cool with the stock cooler on my cummins diesel

Like many have apparently done, I bought these to cool the engine compartment in a mini-excavator. I installed two of them in a push/pull configuration; one runs anytime the battery disconnect is on and the other I can kick on as needed with a toggle switch. I think running two continuously will exceed the capacity of the charging circuit, so only one is full time. These installed easily and they seem to move plenty of air for a small (I got the 7") fan. To address what some have said about not being a true push/pull...you must flip the fan blade AND reverse polarity to reverse the direction and get full air flow. Like most fan blades, these are cupped for greater efficiency, and the blade moves far more air off the cupped side than the other. So reversing rotation is not enough, you must flip the blade too. It's easy; one nut and flip it over. That's what I did on my mini-ex; I mounted both fans inside the engine compartment, the right one blowing in and the left one blowing out, so it will remove the engine heat and pull air across the hydraulic pump. This made a big different in the temperature of the engine compartment. Time will tell how they hold up. If I have any issues, I will update my review.

Really noisy I think it has a bad bearing .they is the second one I bought the first one was ok. Lasted about a year and a half

Works well. Quality is good. Size is perfect for what I need it for.

De très bon qualité seulement que article était pas compatibles avec ce que jamais besoin en dimensions dues le retourner

Todo bien

Decent quality for the price
