Thread: Clearvue CVmax install and ducting

I need some help please. I have the VFD and my sparkie has asked which of the terminal in the main circuit are active either “R or T” (Image below)

my electrician cannot complete until she knows this, Can anyone who have installed a Clearvue before help me.

I suggest you PM NCarcher as he is a qualified sparky or he may reply here.

In this case it doesn’t matter but if you want to get the official word the hopefully NCA will be along soon.

R & T on the Powtran.

have my sights set on the laguna C-flux maybe when carbatec get them in

I would definitly look at minimum 150mm ducting when you do bite the bullet on the p-flux, the dust that my twin dusty picks up through the 225 & 150 PVC is so much better than the normal 100mm

Sorry, I didn't state that clearly enough. Connect the active and neutral to R & T. It doesn't matter which way around. Technically they are both active terminals.

Woohoo.......fired the Max up today, what a machine.........best investment

after programming the VFD and starting low Hz then bought it up to the full 60Hz, hummed nicely.

While it runs at 83db, i do have to say it’s a lot quieter than I thought it would be. My old DC7 ran at 76db so it’s not that much louder

my Exit air runs through the baffle Box and that’s definitely louder but that’s outside and away from our accommodation business so it’s not a worry, plus I still need to insulate the box.

But the suction is awesome, can see why I need to get some mesh on some pipe to stop me losing bits and bobs.

Remote works a treat as does all the ducting, waste bin nice and airtight, but I found tonight when checking it over that the pressure is sucking in the sides of the hard plastic bin..........I’m now thinking of how to re-enforce the bin on the outside to stop this......any ideas are welcome.......or I may have to make some bins out of formply?

so all I need to do now is sheet the room in the MDF I have and the install the acoustic foam, then take another dB reading.

It’s pretty cool watching the dust spiral it’s way down the cyclone

have to say thanks to a few people

Allan and the team at Auto Blast Gates Australia, those gates are awesome, I need a couple more down the track.

Stephen and Karen at Clearvue, we had a few hurdles, not their fault but they sorted them out real quick. great to deal with

Glider, thanks for the chats and help, really appreciated

Cheers

Well done Tuckers!

Paul, try opening another blast gate and see what happens to the bin. I have always recommended a duct opening above the primary work area that does nothing more than draw air into the system and thus pulls air that might have suspended dust in it out of the work area. That duct inlet would have a blast gate on it so it could be closed if needed. That idea works for a single user when only one machine can be used but a multi user workshop where multiple machines are used at the same time could find the permanent open scenario a problem because ideally it needs to be closed when more than one machine is in use.

It is not something I have thought about and the automatic BG system adds another dimension to my idea. It would be ideal if that scrubbing BG closed automatically but the scenario is not common and isn't something I have given any thought to. Again adding another curve into the above idea is when the DE automatically closes down after use the open gate idea falls over entirely but up to now and without the automation that issue has not arisen but it does need to have some thought thrown at it.

Now I’ve got the 2 room filters up and running.......all together should make for a healthier workshop

Finished the new dust duct on the edge sander, all changed to 150mm

new box made for end and allowing for the extra hose and bell mouth fitting for the end sanding

works a treat

VERY clever! Well done that man!

Your setup most likely works because the CV has so much suck but it's not a very efficient way of extracting from a sander. Box junctions are notorious for generating very significant turbulence and restrict flow especially on systems smaller than a CV.

Improved fine dust efficiency can be achieved by completely removing the usual box/scoop at the end of belt sanders and using a BMH at the usual end of the sander like this. Note how it can be pivoted out of the line of the front of the belt for use with longer work pieces.

A Y junction above the sander can be employed to independently connect a second BMH for the other end of the belt such as you are doing.

A mesh guard over any BMH is recommended especially when working with smaller pieces.

So I sheeted and installed the acoustic foam last night, install a couple of vent grills up top for the motor, looks heaps better and the noise has gone from 85db unsheeted and 76db once it was sheeted, but still doesn’t seem that noisy inside the workshop. My DC7 was louder.

Also install an iVac bin full indicator, works great.

But need to work on the outside as I feel the baffle box isn’t dampening the sound enough so will look at making an insulated muffler down the wall........more to follow on that one .....

haven’t figured out how to rotate the images yet so sorry if you get crook neck😂😂
