Cleaning of ventilation ducts in ventilation systems

For systems that look like those in the shared photos, something is probably fundamentally wrong(?). In my case, there are several filter layers before air enters the pipes - they still look as if they were just cleaned even after a year. But of course, they are also smooth. It should be clear to anyone who has taken at least 5 minutes to google that the air does not mix in the cross heat exchanger.

So after 9 pages we conclude:

There are already enough providers on the market. The idea of the OP does not offer any added value. Priced too high for the vast majority. And whether a cleaning is even necessary cannot be generalized.

In my opinion, with regular filter changes and exhaust filters, cleaning is not necessarily required.

Future systems increasingly have inspection openings and the user can easily clean themselves if they want to.

So bury the idea and get back to proper work

You are cool... Who would even bother to create two extra accounts just to talk to you!
Could it be that you are suffering from paranoia.


Mycraft writes or works for Codex. This is clearly recognizable by the images. From his poor style of criticism, one can only assume that someone is afraid of competitors.
People who try by all means to portray their own company as good and others as bad should be banned from the forum.

Bookstar is partly right. Everyone should take a look at their pipes and decide for themselves whether they want to clean them. They should also look at the different methods and question them.

My opinion remains that the pulled method with a pigging device is more effective in cleanliness as well as in time than the reel.
I also do not think much of room filters, as they quickly clog up and thus change the air volume flow. This can have various consequences, which you can research yourself on the Internet.

This is what my exhaust pipes look like after 5 years.

Ours do not. We are in the 5th year, and our pipes do not look like that.
Ours are clean.
Sorry.

LOL, really funny what is being attributed to me here. Not only I, but also most users here in the forum can simply handle the tools that are at my fingertips.

The people who want to portray their company well and others badly by any means should be banned from the forum.

Exactly for this reason, I would be careful if I were you. Because as it looks so far, you are here for exactly that reason. Six posts and so far nothing but promotion of the OP.

I also don’t think much of room filters, as they clog up very quickly and thus change the air volume flow.

Yes, of course the filters clog up. That is exactly their job: they catch the dust before it ends up in the pipes. Then you can replace them and the process starts over.

But seriously now: please quickly remove your filters so the pipes can get nicely dusty and the pigging device can come. Everything has been said here, I would close this now.
