For Sale VW 60mm Diesel Heater Duct Air Inlet/Outlet

[Argent]

Hi guys,

I was asked by a camper converter company to make some air intake/outlets with the VW logo and thought I would post them here if they could be of any interest to anyone.



They are 3D printed with PETG which has very little thermal expansion and can withstand temperatures up to 80 °C, they have a power coated textured finish on the show face and I designed them to screw together instead of snapping on and off.



I can offer them for £5 + £3 postage a piece but if you want to order a few just PM me and we can sort something out. I am also happy to modify and change things like colors, add text if you wanted something to match your van aesthetic.

BEWARE

NOT to be used for hot air outlets though, temperature rating is far too low for safety.

Hi Argent

They look great, what is the diameter of the end cap and also the cylinder part please?

60mm for the ducting end and 84 for the logo end. However I can make them any dimensions you want. I have also printed them successfully now in ASA so should give a lot more thermal resistance. I would have to charge slightly more for ASA being a more expensive and tricky filament to print but I would suggest PETG for air intake and ASA for output.

 

[oldiebut goodie]

ASA is not suitable either - it is rated for 93 degrees, still far too low for manufacturers temperature resistance requirement. It must be able to withstand 130 degrees permanently as detailed above.
I would suggest that you do not use either for outlets. I have measured 110 degrees at the outlet of several heaters. Even higher on the odd one.

As per @oldiebut goodie these cant be used as an outlet for your diesel heater. The air coming out of your heater will be well in excess of 100+C. This will not only pose a fire risk but may pose a health risk with possible fumes.

Please dont take this as putting down the use of 3d prints but having had PETG approach its glass point (when it becomes soft and malleable) just in the sunshine, its got no chance when coupled with a heater.

As someone that also dabbles with 3d printing, the materials that are easy to print with and available to home grade machines and users are 90% not suitable for use with a heater.

Would be great for a dropout vent though.

Hi Argent,

Perfect will pm you.

I would disagree with PETG approaching glass point in the sunshine, it would need 70°C minimum (filament dependant) and I have had PETG prints in a car in Southern France at 40°C outside temps and still did not become soft. I think you may be talking about PLA which would become soft in the sun.

However being unfamiliar with the heat at the outlet (after the length of ducting) I have printed a batch in ASA which has the following properties:

Vicat Softening Temperature 106 °C
Heat Deflection Temperature 100 °C
Melting Temperature 210 °C

This is actually not too dissimilar to PC which is generally used by companies such as Webasto previously quoted.

 

[oldiebut goodie]

Webasto outlet hoods are PA6.6, same for vents.
PC is only rated to 120 degrees continuous.

As you'll see this Webasto outlet hood it is made of ABS and fits directly on to a diesel heater outlet.

 

[oldiebut goodie]

Don't believe AI descriptions.
Look at the hood and vent - the plastic is marked inside. Clearly PA6.6.

 

[Argent]

All the ones I have purchased and used from Amazon are ABS. https://amzn.to/3YUNI0m for example.
I am sure that there are ones made of Nylon but I believe they are overengineered as I am sure Webasto sell ABS outlets. I would happily use ASA which is superior to ABS.

Also this Eberspacher outlet listed on a reputable website. Eberspacher Heater Outlet Hood | 251729010500

 

[oldiebut goodie]

Webasto do not use ABS - your Amazon link is for copies not original Webasto products. Why risk a £1500 heater for the sake of an OEM £6 vent?
Hopefully the heaters that you are fitting low quality vents to have good overheat protection and shut down before damage occurs when you have a vent collapse shut due to melting/distortion.

 

[Argent]

I listed you a Eberspacher outlet from Butler Technik and here is one from Webasto - Webasto Air Top Air Evo 40 55 Outlet Hood both made in ABS. I also mentioned that I used ASA which has superior heat resistance to ABS.

Please avoid exaggeration and fear mongering. I don't know of a single Diesel Heater that costs £1500, I'm sure there is one but I'm pretty sure that 95% of this forum have heaters under £1000 and I would hazard a guess that a good proportion are using vents from Amazon, Ebay or Aliexpress that are made of ABS. Also stating OEM £6 is a rather big understatement when the average online price is over £10 for the equivalent size. I think it is also very small minded to say "low quality vents" when you have no factual reason to make such statement.

I've had an Amazon ABS outlet fitted to my Eberspacher Airtronic D2 for over a year and it looks the same as the day I bought it.

 

[oldiebut goodie]

I am sorry that you are so blinkered - I have many experience years of selling and repairing Webasto heaters. I am not exaggerating at all.

£1550 - Webasto Air Top Evo 40 Motorhome RV 12v Diesel Air Heater Kit This is what I have fitted to my van. Final cost was £1800 region with extras.

Vent - £6.35 ( they have gone up a little) Webasto Air Top Heater Ducting Outlet 45 Deg 60mm 1320204A I don't know where you are buying from to have to pay over £10.


Go ahead and sell sub-standard vents - I hope that you have good liability insurance. I think that you will find that Webasto know a little more than you.

Show me the hood from Webasto that is marked ABS. I have shown you what Webasto supply above.

 

[Argent]

i don’t know what blinkered means, and it also doesn’t add up why you would have so many years fitting and repairing heaters yet pay someone to fit one for you for £1800. Each to their own.

The vent you just linked is £17 delivered, far from £6.

Carry on insulting peoples intelligence and work, I dont’t believe what I designed is sub-standard. I have shown you the Webasto hood marked ABS Webasto Air Top Air Evo 40 55 Outlet Hood

 

[oldiebut goodie]

I didn't pay anyone to fit mine - I had a choice of around 30 in the workshop to choose from and fitted it myself.
I am sorry but until you show me this hood marked ABS I maintain that you are incorrect. You are just relying on advertizing blurb to state your case. I have shown you several times what Webasto components are made from.
|I am not insulting your intelligence and work - I am merely pointing out that that it is not safe.
