Matthew P Posted July 21 Report Posted July 21 So, last weekend I replaces the wire running from the overhead to the outside airs scoop, whomever did it previously only had it to where the air scoop raised about 1/2 an inch and didn't allow for much airflow. Well, it opens up about 1.5 inches now and allows a bit better airflow but with the current interior vents it doesn't disperse the airflow very well...Just wanting to know what options might be out there to improve, not only the amount of air, but the displacement as well...I saw this picture in an older fourm but it didn't address the airflow, was just in with other pics that the OP did to his aircraft....any ideas? V/r Matt

V/r That picture is my plane. I copied @Utah20Gflyer in the post listed below. I built a simple vacuum forming box and used 1/16 ABS to make mine. I bought the wemac vent from ebay. They are a game-changer. It directs airflow directly wherever you want and the aft vents can be directed at the pilot as well. Also, someone just uploaded a 3D print version on thingiverse a few days ago. Search Mooney. 1

Found it: https://www.thingiverse.com/thing:7093747 Very helpful! Though the eyeball vent part is for a beech-style old vent. wonder if anyone might update the file for the standard round ones one can get on spurce?

Bartman Posted July 27 Report Posted July 27 If not already done, consider removing the air plenum and remove the “hog hair” fibers. This acts as a filter and if you were flying in rain with the vent open it would allow it to drop out and drain, but who flies with the overhead vent open in the rain? I found the filtration benefit did not meet my expectations and it acted more of an impediment to flow. When we redid mine a few years ago I also rigged the new wire to open a bit more than previous. It now opens about an inch and I now enjoy much improved air flow, but it does adds drag and decreases airspeed a few knots when open. I have no regrets about those minor changes.
FlyboyKC Posted July 29 Report Posted July 29 I just built these vent deflectors for my Mooney. I 3D printed them using PET-G filament, mainly because of the heat the plane is exposed to in the hot summer sitting in unventilated hanger. You can download the 3D files from this site (still a work in progress) https://www.mypilotflyer.com/3Dproject.html NOTE: if others have 3D parts they would like to share I will add them to my website for download. My goal is to share projects throughout the community.

Old Chub Posted Monday at 02:19 AM Report Posted Monday at 02:19 AM (edited) Hi everyone, Based on the strong interest I’ve seen for a solution like this, I’ve gone ahead and started designing a replacement overhead eyeball air vent for our Mooneys. After some prototyping and refinement, I'm happy to share that the design is moving forward and is close to ready for production. I will make the promise of getting any order shipped by August 29th 2025. To get a better sense of demand and help fund the initial run, I’ve opened preorders on my website. If this is something you've been looking for or needing, you can check it out here: https://www.smcustomproducts.com/shop/p/mooney-m20-overhead-eyeball-air-vent Your feedback and support are really appreciated—whether you're ready to preorder or just want to share your thoughts. I'm always open to suggestions as I fine-tune the final version. If you aren't interested in a Preorder and would just wait until I have the production unit ready you can fill out my contact page here and I'll email once it is ready: https://www.smcustomproducts.com/contact Thanks for looking and fly safe! — Sam Mose, Old Chub Edited Monday at 02:22 AM by Old Chub 2
EricJ Posted Monday at 02:41 PM Report Posted Monday at 02:41 PM I would suggest leaving the end either just a hole or completely unfinished so that any vent could be used, like the following: https://www.amazon.com/EATAKWARD-Universal-Shuttered-Dashboard-Replacement/dp/B0DPYHGMWM

I'm frequently hitting my head on things in the cockpit. Unless there's a functional reason, think I'd like to see it as flush with the headliner as possible while still improving the angle and flow towards the occupants. 2

All the others I’ve seen have been goofy looking when installed bc they are so long.

Thanks for the suggestion - I'll incorporate a more flush design and see how it fits with the headliner, I have a trip planned this week and didn't want to take apart the headliner panel just yet.

It might have something to do with the structure of the plenum in the roof, as well as the ability to mount the vent adapters.
