Airflow Airflex or Zehnder Comfotube?

[Jambutty]

I’ve read that there’s a lot of difference between manufacturers but these 2 seem quite well regarded and are coming in at very similar prices. 
It’s purely for extraction so which one would you go for? 
I’m swaying more towards the Airflex but using the Zehnder duct clips, all from the same supplier.

I used ubbink 90mm and all their fittings, no issues

Unbbink, I’ll check them out. Where did you get it from?

Came across this, which is the cheapest I have found - https://naturalgreenheat.co.uk/product/90mm-semi-rigid-duct-50m/

That is a good price but I’m after 75mm, I’ve just ordered the BROOKVENT airstream ace with the 75mm spigots!

I've used Airflow Airflex, with Airflow manifolds, terminals, joints etc and all went together very well.

Best price I could find was via Travis Perkins. They're a distributor for Airflow, but don't seem to know anything about what they're selling, so you need to give them all the part numbers for what you want.

They do 75mm stuff too and it’s almost half the price of the Airflow or Zehnder (ducting)

 

Specs look pretty good too with the plenum being long enough to mount on floorboards upstairs and have enough length to penetrate the ceiling. 
 

I’m going to price it up and see where I get too on it. 
 

Have you used the Aria before?

No, but I need 150m of the stuff, so I'm seriously considering it.

It actually looks like really good kit, I did see it on BPCs website but dismissed it was it was similarly priced to the Zehnder and Airflow stuff which are more recognised. 
 

I spend hours procrastinating over things like only to fit it and never give it a second thought once it’s in.

Quick update, fired a few question over to natural green heat and got a reply almost instantly so ordered the system (duct and plenums) Shortly after ordering got a call from them explaining how the Heatpex system goes together and confirming it’s all ready to be shipped! 
I can’t remember the chaps name who I spoke to but he was extremely knowledgeable on the product, gave me the company backstory and I’m glad jayc89 put me onto them👍

 

For anyone contemplating 75mm or 95mm ducting pick up the phone to them for some good honest advice. Companies like this are rare so we have to keep them going🫡

So I’ve half fitted the system and the Heatpex is brilliant, the tube is flexible and the fittings are great. The 3 ports on the plenum are quite bulky but it’s not been an issue. 
Thank for pointing me in the right direction for a supplier, I’ve got 1 plenum and I should have some ducting left over. If your local to Frodsham your welcome to take whatever’s left👍
