If you have the room to fit it, an EB Pabst brand German fan stays silent even when the blades get gunked up. Bearings in this fan are huge. I also agree with Landyacht's choice of fan.

Older big rigs used to come with encased in wire fans that vibrate so bad they would snap rivets on a Peterbuilt cab. Squirrel cage fans are not easy to clean. And they are death with small motors and bushings instead of ball bearings.

Anything greater than 150 CFM (more or less) may disturb flame pattern on stove top burners.

I have one. DW loves it. It's much quieter than the old one and has 3 speeds. The LED light is a huge improvement, can now actually see what's on the stove. And it's also got a night life setting. It really does move a lot of air, no more setting off the smoke alarm, plus you can open the vent from inside.
If you're replacing a ventline brand it's pretty easy. Just unscrew the fan box and screw in the new one. If you have a hengs it's a lot more work because the fan box is spot welded in so you have to drill them out which is a tedious.

Here's a post I made several years ago about adding a PWM controller. That's a big help, but only if the fan noise is acceptable at full speed. If not, then you need a different fan plus maybe a PWM controller.

I replaced the vent fan in our Bpunder, used a spare computer fan and some fairly thin mild steel sheeting. DW loved it and I'd do the same with our Winnie except that the exhaust fan it in the MW/convection oven.

I installed the SAM-1 & love it. That said, I've read that the manufacturer is no longer making them so availability is limited. It is still listed here.

I pulled one out of a 1972 Winnie and eventually used it. The motor is really big, the fan aggressive and it is super quiet, and moves a lot of air. If you get lucky to score an old fan like this it should fit into modern hoods.
Back then the vent filters were bigger too.

The noise likely is from your fan blades. Fan blades with rings around it, where the blades are connected on the very ends with a hoop, will be more quiet and more efficient.

I replaced the OEM fan in our hood with a Silverstone 180mm fan (don't recall the model) about 6 years ago, and it runs so quiet I added a small red LED next to the switch to remind us when it's turned on. It moves plenty of air, and I used the same type of fan to replace the noisy OEM fan in the bathroom as well. I didn't see any need for the included speed control in either case.

It moves a fair amount of air but.. The range hood on an RV is an exhaust fan. now this fan sends air outside via a "Flapper Valve" On most RV's the Flapper is OUTSIDE and is locked closed by a pair of twist tab. you have to UNLOCK it for it to open and let the air out.

on some (Mine) the flapper is INSIDE. and the latch is up under the hood on the Right. as I recall Pulled out (it's a piece of spring steel) is OPEN but don't quote me on that. I had to take the hood apart to figure it out believe it or not.


Home is where I park it.

Our vent latches inside as well, and I put a small label by the switch that says "Vent unlatched?" as a reminder. Our previous RV had the vent latches outside, and I used the same label inside.
