Just to add a bit more to this and something that is not generally known in Oz. Bill Pentz when he was campaigning for better dust control was the first to do so and a lone voice in the wilderness so to speak with not many supporters. As he got more evangelical about the whole thing he met with a lot of opposition from the vast majority of American woodworkers and was basically run out of town being banned from forums and the like and I would hazard a guess that the opposition he encountered has left him with a less that enthusiastic approach to his website but it is only a guess on my part. He was an infrequent poster here years ago but that has ceased though he may read as some do. Before anyone gets all religious about fine dust control there are some in this place that still do not believe and I experienced some strong criticism even in this place from some who are current posters saying that a Clearvue was basically a waste of money when I first started selling them in Oz.

I think it would be safe to say there would be no direct comparative test available. Will it extract dust and chips? yes it will, will it do the job to the same level as a CV, I doubt it but I will venture a guess and say no and it is more expensive than an CV1800 and about the same price as a CV Max. The ducting is or should be the same or near enough for an 1800 but a Max will cost a lot more due to the increased main duct size required. The footprint required for a Max/1800 would most probably be less but once in place the CV is not going anywhere where the CT linked machine is mobile. The problems with the linked machines preventing an equal performance to the CV are several including the length of the cone, impeller size, inlet configuration etc. I am sure BobL can expand more fully.

The shape and angle of entry of the inlet to these cyclones immediately tells me that both of the machines are an old (1960's) design.
This older design doesn't matter so much if a 20HP motor and a 20" impeller are used but results in poor performance with smaller motors and impellers.
The older design means greater back pressure hence lower flow, and poorer fine dust separation, compared to the ClearVue.
The Clearvue uses a rectangular ramped inlet and this makes considerable difference.
The 3HP motor and small impeller used in these also means that they will not sustain air flow under back pressure (resulting from ducting, junctions and the cyclone design itself) compared to the larger impeller and motor on the Clearvue.
