wyobob Posted November 20, 2009 Share Posted November 20, 2009 (edited) My DA has no air cleaner and as I live in dusty Wyo. and drive it on dirt roads some, I wondered what would you do for a good air cleaner? Thanks Edited November 20, 2009 by wyobob left out a word (see edit history) Link to comment Share on other sites More sharing options...
Bob Zetnick Posted November 20, 2009 Share Posted November 20, 2009 Your DA should have an air filter. It's not a disposable filter like you'd have now. There were just steel blades on the underside of the air filter. From what the previous owner of my 29DA said he would just put vaseline on the blades to catch dust and clean it off every so often. I can't confirm if this was actually recommended when the car was new. Link to comment Share on other sites More sharing options...
keiser31 Posted November 20, 2009 Share Posted November 20, 2009 Here are photos of a 1929 DA and 1930 DD air cleaner. I believe they are the same. Of course, my area is 1931s, but this could be correct. Sorry for the non-clarity and obstructed view. Maybe someone could post a better photo for you. I have seen them on ebay occasionally.

Bob Zetnick Posted November 20, 2009 Share Posted November 20, 2009 Here are a couple of photos of my 29DA carb w/ air filter; air filter to upper left and in the more horizontal shot you can somewhat see the "blades". I have seen a couple of these on Ebay the last 4 months. Link to comment Share on other sites More sharing options...
Bob Zetnick Posted November 20, 2009 Share Posted November 20, 2009 I have a Stomberg U2 which is what came on the car when I bought it in '71; I assume it to be original. Link to comment Share on other sites More sharing options...
Guest 1930 Posted November 20, 2009 Share Posted November 20, 2009 U-2 is original and I dont think it was ever really designed to be an air filter, the steel blades are designed to give the air a turbine affect but as far as I know do little to nothing to keep out dirt, I have read suggestions that the turbine affect and shape/angle of blades will throw any particles outward and out before they enter engine but I dont know that to be true.

Guest oldodgeboys Posted November 21, 2009 Share Posted November 21, 2009 Years ago some military helicopters used particle velocity separators. I think they were developed as part of a sand separation system for Middle East action. The particle would enter the intake at a high velocity, and then the air path would make an abrupt turn...the weight of the particle drove it into an exit port.I dont think it matches exactly what the DB air cleaners are trying to do, but it's the same basic idea. I'm not to sure the concept would work well at lower air velocities. Link to comment Share on other sites More sharing options...
wyobob Posted November 21, 2009 Author Share Posted November 21, 2009 Thanks, I am a little nervous about the ability of the originals to protect the engine, has anyone used a modern filter & if so, what? Link to comment Share on other sites More sharing options...
nearchoclatetown Posted November 21, 2009 Share Posted November 21, 2009 One of the foam socks meant for a dirt bike stuffed inside the original filter should handle any concerns. Link to comment Share on other sites More sharing options...

Guest 31DH Posted December 21, 2009 Share Posted December 21, 2009 WYOBOB,You wanted to know of a good air filter for driving on dusty roads. As far as I'm concerned,the tin can with fins that came originally with this era of cars is for show only!( you notice I didn't even call it a filter.)I have just installed an air filter from "snydersantiqueauto.com" on our 31 DH . ( Picture attached.)The ID is 1 7/8 " where it fastens on to the carb.It fits over a tillitson JR1A or use a short piece of pipe to go to a Tillitson JR2A or a Carter DRT-08.The paper part of the filter is 13.3 " cir. and 5" long. 66.5 sq.in. They are produced for Model A's. I have been using a filter 56.5 sq.in. for the last 20,000 miles and the car seemed to run okay. If not, there is room for even a bigger filter for this configuration.Glen. Link to comment Share on other sites More sharing options...
wyobob Posted December 23, 2009 Author Share Posted December 23, 2009 Thanks Glen, that looks like a great setup! Link to comment Share on other sites More sharing options...
Povertycove Posted December 28, 2009 Share Posted December 28, 2009 Before buying an original aircleaner on Ebay (in great shape, but it cost over $60!) I made a cleaner out of wire mesh, covered by standard black air cleaner material, and attached to the intake by a stainless tension band. It was easy, and effective. Roads were awfully dusty back in '29, but they changed oil every 1500 miles. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted December 28, 2009 Share Posted December 28, 2009 I'd buy a motorcycle filter for everyday and take it off for shows. Link to comment Share on other sites More sharing options...
