apparently, they use this principle for axial fans on military submarines....amazing what you can find out on the web...
Right - (handbrake sorted now btw) been doing some further experimentation with silencing the thing. Best so far is using the heat exchanger hoses. One on each side ie heat side and cool air return silences by a whopping 10db (and possibly slightly more). It is a very noticeable difference. Not sure what to do for now as two of these take a lot of room up (although they are designed to be outside and get wet so if you've an external syatem then try em in line with your ducts). Cheap at the mo ie about 15 quid with GSF weekend discount. Bought one last week. Think I may hold off faffing for now as ideally I would have these outside which again means modifying the 90 degree arrangement for the outlets. You wont have that issue on the gas only version!
@Bertie the Bus You got yours installed and finished yet! Looking at modding mine now to fit between chassis rails as per your install.
How long are the bellows things you've got? I was grovelling the other day & noticed the paint is blistering on the mandrel bend that goes from the hot air out hose on the unit into the van. It must get bloody hot coming out of the propex as the flexible duct at this point is about 40 cm long IIRC
mmm that may work as a silencer in line under the van as there is a small 's' in the current duct. will have a measure, cheers
im off home at lunch. can measure but they are the same as you have on your bus from heater control box to body. they can be reduced in length btw as the ends unscrew.
Unfortunately not. Health issues and other non bus related jobs have restricted me but I am hoping to get back to the bus over the next couple of weekends! Sent from my iPad using Tapatalk
Hi Chris Have been reading (most of this) thread. I’ve PM you with a quick question that I have managed to turn into waffle! P.
Show me your brackets!! So this is where I'm at. On holiday and the kids and Mrs are away. So I thought this is perfect for me to fit the old propex underslung. (I'm tee-ing into the underslung lpg tank). And I've done as much as I can on the bench. I just haven't got the vision of how to secure it in place. The only bit of room I have is front to back across 2 top hat sections. I don't want to be drilling and get it wrong. I've looked through this thread at all the photos but just can't see how to secure it. Any help advice much appreciated. I know this project has broken all records for procrastination so no need to go on about that art as it turns out it was with good reason! Cheers P Sent from my SM-G780G using Tapatalk
@ginger ninja Paul, can you straddle the top hats? If so then a couple of bit of flat bar, think I used 4mm coz that's what I had, gives you the option to have 4 or so small bolts and nylocs along each side... Not great shots but this is what I did...
Funny as it happens I just saw it as you sent this. Thanks so much it has given me some hope! Still scrabbling around on your back with a drill, you got to get it right. Quite scary. I will bolt something like this to across the top hats.
