View Full Version : Some general advice on a Clearvue cyclone installation?

Well I am looking at finally addressing dust collection properly in my workshop and am considering the Clearvue's. I am leaning towards the CVMAX to have that extra power on tap, though not sure if it is really needed in my case (only ever running a single tool at a time).
My workshop is a four car garage (that I share with a car from time to time). I will need to have extraction points to most of the garage area.

Now I have the option to put the cyclone inside the garage in a corner and vent out a side window, or put the whole unit outside. Putting the unit outside has some advantages in that the house backs onto a bush reserve and noise could be directed away from neighbours. Also it would save space in the workshop. The issue with the outside option is that the cyclone would be 1 floor below the garage level (adding to the length of the duct run) and also would require a 90 deg turn at point of entry into workshop (i.e. duct run up outside wall of house then an elbow and entry through an existing wall vent). Looking for any opinions on whether the penalties (to airflow) of doing this would outway the benefits of not having it inside the workshop?

I'm also giving consideration to noise control, especially if I install inside the workshop. I have seen various plans for mufflers. I would like to achieve the quietest installation possible. One idea I have is to use wall space around the cyclone to build a kind of baffle box. The idea is to use a large, shallow depth box with internal walls that present a zigzag path from entry to exit. Cross sectional area of the path would be equivalent to 8"-9" round ducting (or whatever is required for the cyclone exhaust). I would likely make the box out of thick mdf as well as other sound insulating material of some sort. The idea of this approach is that the multiple changes in direction of the exhaust would help cancel a lot of the noise before the exhaust is vented outside. Has anyone tried anything like this? Anyone have experience that would shoot down this theory?

Hi Oddy,

I plan to put mine inside my workshop in an enclosure. I'm building it out of multiple layers of MDF and using a product called "QuietWave" between the layers, and then lining the inside with 50mm sound absorbing material which has a 60kg m3 rating. At this stage I'm looking at a zig zag method for air flow, but I'm still looking for other ideas. I'll make a removable door than can be lifted off for easy access, but then screwed back in with threaded inserts for the best possible noise reduction.

I think you could hang the cyclone on the outside of the wall at the second floor / garage level and have the long pipe from the bottom of the cone to the bin at ground level. The Clearvue people can confirm whether the long drop would be an issue or not. You get to eliminate the 90 deg turn and the extra pipe to the ground. Harder to access to service though.

Another possibility if you have enough attic space above the garage. The cyclone can be situated up there and exhaust out through the roof or out a gable with the collected debris dropping into a bin in or outside the shop. The cyclone will work even if mounted on an angle to match the slope of the roof. Clearvue actually found they will work while horizontal but the big stuff stayed in the cyclone and rattled around. With the unit in the attic you have the space to make any kind of mufflers for the exhaust.

That's some great lateral thinking Pete.
I thought of mounting the cyclone up there but the waste bin emptying was going to be the problem - I didn't think of a long pipe down to a ground level bin! The pipe would need to run at an angle though to put the bin out of the way, so I would be a little worried of stuff getting caught up in there. The other issue in my circumstance though is that it would be a bit of an eye sore up there - the place I have in mind for the cyclone is tucked away beneath a verandah with the pool filter. Unfortunately I have no roof space for storing the cyclone - there is a room above the garage. That's interesting though that they can be mounted at an angle :o
