Could someone please identify the blue part ?

[Bert bassett]

Hello,
I am trying to tidy up the area up in the picture......
I have no clue what the blue part is......
I want to replace it and change its position......
so any help would be appreciated......
I have searched so many different things and I cannot find anything similar

Many thanks if you can help... just hope the picture is attached !:smoking:

it is a de aerator, go careful with moving it

Thank you very much, that was quick..... are they fragile...... or just awkward ?

Airjec sludge buckets

Tear it reet out haha

Fragile and can split if you move the pipework.

Interesting and thanks......To 'tear it reet out'...... would I just add the feed above the loop, and the expansion above that ?

I don't think Myson still do them but use the above if you are re-piping.

Only people with dirty systems complain that that are no good !!!

If you don't what to fit one back go you a standard 'H' frame arraignment.

Get rid. Have vent going up from RH pipe, tee off to connect with horizontal pipe going to pump and tee in cold feed to same horizontal section. Offset vent with 45 degree bends to avoid horizontal sections. This assumes pump is pumping down,which is contra to connections on airjec but the other way would require pump re positioned on RH pipe and vent continued up from present pump position.

I think these MAKE systems dirty?

I think these MAKE systems dirty?

They don't "MAKE systems dirty" what they do is to block up if you have a dirty system.

They are designed to remove the small bubble of air that cause the corrosion in the first place, these are held in solution due to the velocity of the water moving around the system. We have all heard the slugs of air race through the pump long after the system has first been switched on.
The effect of the water entering the larger volume in the air separators causes a large drop in it's velocity which allows the small bubble to escape, join together & rise up the open vent to atmosphere. Unfortunately if you have a dirty system this drop in velocity also allows the dirt to drop out of solution & build up in them, just like it is designed to do inside a Magna clear type filter.

Please don't blame them for a poorly maintained system thereisa..

Double post again is it me Mod's / Dan?

Airjec belongs to the age of Ronan Point and should likewise be confined to history. One lesson from Ronan Point is that any design needing a disproportionate reliance on everything else being correct, is a fragile design.
The OP picture demonstrates what happens when product marketing a supposed fix ignores basic principles. Glaring example is pump should be sucking from lower connection (one opposite cold feed) and vent pipe needs to rise as near vertical as possible. (nothing less than 30 degree to horizontal).
In any system, small air bubbles will migrate to highest point once pump is turned off and pipework designed accordingly will not need Airjecs.
