RV Airflow

[Dick Noble]

Just finished installing the RV Airflow system. Noticeable increase in air flow and decrease in noise.

If you have 2 units, and with the track layout on Solitudes/Momentums, you can probably see and even larger increase with both units. We did all three in our Momentum and HUGE difference.

Agree we have noticed a huge difference, wish we had done it sooner.

Same here. Installed two of the RV Airflow System units and its a whole new environment. Had enough airflow to add an ac vent in the ceiling of the front closet.

I concur - the improvement in air flow and reduction in noise in our Imagine is significant. Even with a very hot and humid summer we have not had to run the A/C on the "High" setting at all - just used the "Lo Cool" setting and perfectly comfortable. And we like it 'chilly' at night too

Pretty expensive for a piece of molded Styrofoam and a couple of plastic gaskets, but at least it works as advertised. I installed it in both A/Cs and the difference in air flow is considerable. In the end, worth the expense.

Agreed with worth the expense. We did all three in our 351M, and we maintained 75 inside with 118 outside, made it all worth it.

GD is now installing these on some of it's newer units. You can order from a GD dealer for around $55 each:

Steve....is that a knock off of the RV airflow?

Don't know, but I think it's the real deal.

It's the real deal. GD and RV Airflow have partnered and GD is buying massive quantities. Though I haven't heard of any dealer willing to sell it at its cost, which is what was posted - our dealer marks everything up two-fold (not an exaggeration). The OE P/N also doesn't include the transitions, but shouldn't need them as they're factory pieces on racetrack systems.

Alternatively, if you attend any Rally RV Airflow is at, the rally price is a big discount.

Thanks for the tip! Looks like it’s for Coleman Mach 3 which is great for all you with newer units. We have Dometic Brisk Air 2 which RV Airflow supports but it does not show up in the GD parts list since it appears they don’t use Dometic any more.

I have one for the second AC I installed that is still sitting in the box. I guess I need to get off my duff and get it installed.

I'm going to make my own with help from youtube. A box knife and a sheet of ridge foam insulation.

I'm thinking about doing the same to both of my AC units. Which YouTube video are you using? Seen a few different variations and I'm not sure which one is best.

The one drawback is the efficiency improvement is increasing airflow out, but not in, so the return is a bit of a choking point. If you look at the RV Aiflow design, the address this issue with increasing more surface area to the return.

I've looked at a few. I'm still in the research mode.

I'll look at that Curtis. I studied HVAC in school many years ago. I understand airflow. The easier it is to get in, the easier it will be to move around. Less sharp corners and flat dead ends.

The ac mod has already been proven to provide increased airflow, however, I do agree that the mod versus rv airflow product, rv airflow will win for exactly the reasons stated, mod has less cubic area for air return and sharp corners versus smooth curves and greater air return capacity. Home made version will still net substantial gains.

Also chiming in! Like many, we're here at the GDRV National Owner's Rally.

I bought two Airflow kits yesterday and installed them. The wife actually asked me to turn the temperature warmer! Our middle A/C never seemed to be that great until now. And FAR quieter.

We have three A/C units, so I went back this afternoon and bought another!

Now I just need to install the two SoftStartRV kits! Shouldn't take more than an hour, but the wife knows me well -- "so it'll take you three hours?" so I can't start on it before the Casino Night now!

Care to share if you got a discount and how much?
