Thread: Sourcing an impellor (importing a ClearVue unit?)

I started looking without much luck. I haven't been finding time lately though to continue my cyclone project. Soon as I have some free time though I will be back on it.
The simplest and most promising lead I had was to purchase a Jet blower unit. I contacted Jet Australia (via a dealer) for a quote on the 1900 unit. They gave me a quote on the DC-1200 fan & Motor assembly but never got back to me on the 1900 after I chased it a couple of times (the 1900 is a 3HP unit with a 14" impeller). The quote on the 1200 was RRP $553 (incl GST) plus freight.
I haven't contacted ClearVue yet about importing their impeller, but from posts I have seen from them they seem pretty accommodating to this sort of thing and the exchange rate is improving.
At the moment I expect to buy a local motor and import just an impellor when I can find a source (possibly Clearvue).
Another interesting find was that I have seen some relatively cheap digital inverters for sale on ebay (see the kbe2 models on this web page: http://www.kbelectronics.com/catalog_kbe2.htm). I saw one suitable for 3HP motor go for around $300. These inverters can run off my single phase 240V 50Hz supply and drive either a single phase or a 3 phase motor. They also give me soft start, speed control (1Hz-200Hz), overload protection and even braking if you want it. This solves a lot of the design issues when you are building off US plans with impellers etc designed for the faster speed 60Hz US motors. I need to research this a little further but sounds like a worthwhile feature to have on the cyclone and would allow you to ideally tune the motor speed to suit your overall setup.

Thanks Oddy, I will have to keep looking. Seems like the Jet, is probably the easiest option, for us here in Aust.

Apricotripper has the Clearvue, he has shown it on the forum somewhere.

Thanks for that, however I have read the post on the Clearvue, but that was on the whole unit, I am only interested in importing an impellor from Clearvue and making my own blower case with a Aussie sourced motor.

Hi,

Try GRIZZLY in the USA, they sell spare parts for all their machines.

Hi,

Many many years ago when all this info about Bill Pentz's cyclone started on this Forum, I looked into buying an Impeller in Australia. I contacted Aero Tech Fans and they quoted about $600 for the impeller. (Remember thats about 7 years ago.) And I'm guessing they aren't cheaper now.

I think the cheapest way is to buy a good quality 2-3 HP industrial Dust Extractor (1700-1900 CFM), and modify it for the Cyclone. Unless you can roll/fold all the components for the cyclone, then you will have to get a sheet metal fabricator to do the job. All up, if you get any change from $1000, then I reckon you have done ok.

I'm sure some will say "you could do THIS or THAT and save heaps", and I reckon go for it. The cost will depend on what resources and skill you have access too. If you can get access to the Blueprint plans of a high efficiency Material Handling Impeller, then you could have a crack at making one yourself.

GOOD LUCK!!!

Thanks for the replies thus far. Yes, enquiries for Aussie sourced impellors are at least $1000 (just the fan) while you can buy a bare motor/blower complete ( Similar to Jet etc) without bags etc for half that. So, while possibly not as well made and efficient? definitely worth doing the sums.

You could always buy two smaller units and run them in parallel to double the cfm, I'll be doing my new set up this way no cyclone tho, just a common baffled chamber with 2 PFC filters sitting on top.

Hi,

I'm not an aerodynamics engineer, but I don't think that air flow in dust collectors will work this way. I don't think that two 1200 CFM units connected together will result in a 2400 CFM capacity set-up.

I suggest you try to get more info about doing this, before you part with any money.

Worth looking at, good luck.

Glen.

In parallel you will get double the air volume capacity.
Essentially they are not connected together they share an inlet pipe and y duct(must be sized accordingly to flow needs) then output into a common chamber, think of it this way 2 water pumps filling a tank at the same time will take half the time 1 pump will.(providing inlet feed is sufficient)
If you connected the water pumps in series you will not gain much if any flow capacity, but it will increase head pressure at given distances between pumps.

Its the same as twin turbo cars(DE fans are the same as the compressor side)rarely do they put them in series(sequential set up only)they run a identical pair in parallel into a common chamber(manifold or intercooler).

thanks for the info, but one larger unit should work out cheaper and take up less room etc.
Twin motor vacuum units are a good example of what you are saying.
