Tunze Classic 230?

Roger,

I have a Tunze classic skimmer that I need a silencer for. It looks like the now obsolete ones, 235 I believe except my "body" is longer and the pump number is 233.02. The silencer appears to hook into a venturi hole in the pump output nozzleand then into a pipe with a wing nut regulator of some sort that fits into the silencer.

Looks like mine needs a flexible tube that's a bit longer than what one might have on the most recent 235 series that I see in the catalog.

Will the 230.49 silencer work or will I have to retro the tubing and is it some metric size that I'll have trouble adapting?

Embarrassingly enough, I had the part but it "grew legs" as my dad used to say when I was looking to use it to do a temporary fix on my Comline in-sump skimmer.

Also, there are a variety of holes and openings....one drilled in the clear acrylic riser tube just above the water line, and 2 in the brown ring that the skimmer cup sits on, a small one that would likely be for ozone and a large one that I would suppose should be the air input regulator....but if so, what's the wing nut for on the tube that connects the silencer to the riser tube?

I really don't need to get this skimmer running, but a good old classic like this one would be quite the conversation piece on my reef tank.

Your advise, as usual, is appreciated.

You would have to essentially build a silencer but I have the parts and if you have the wingnut and the stem it is still possible. The large hole in the brown ring is an air intake, the small one is for optional ozone addition. The large one in the clear body is to allow the water to pour out since some water is used to form a gasket for the cup and keep the foam moving upwards. The wingnut is your adjustment for the venturi. The air comes in through the large hole in the brown ring, travels under and around the cup, goes through the tube with the wingnut, through the silencer and into the venturi.
