One dust extractor or 2 smaller cyclones?

[Albert Lee]

I have been wanting to upgrade my dust extraction system for awhile now, was looking at the Dantherm S500 (5hp 3 phase) combined with S750 filter (30m2/243 sq ft)

The cost of a S500 with S750 filter is about 2-3 times the price of a smaller cyclones (depending on where you buy)

I have limited shop space, I can fit the Dantherm unit in, but its not small, the footprint of the Dantherm S500 with S750 is about 4 times the size of a 3hp cyclone, cost is about 2-3 times the cost of the cyclone pictured above.

I know a lot of you will say ClearVue but where I live by the time I have a ClearVue CVMax delivered to me it will cost about $3800 USD, I could save $200 by driving to the Airport and collect it myself. And personally the heavy plastic and MDF component of the Clearvue dosent really attracts me.

Most of the time I probably only need one cyclone... its only when I use the wide belt sander I will need the Dantherm. (yet to decide what sander to buy)

So, A Dantherm S500/S750 or 2 smaller cyclones? (I probably answered myself...)

For the same HP, you will get more airflow and better filter life with the Dantherm.

The cyclone you pictured will likely not do very well on dander dust. This means you will have more carry over to the cartridges and have to clean them sooner.

Those two choices are not comparable. The Dantherm is by far the best choice with a sander. You will be impressed with the build quality too. The commercial units are a whole different deal than hobby type collectors. The short cone cyclone is a compromise and the cartridge won't hold up to a WB. Dave

This is just my experience but I will never again buy any kind of dust collector that uses plastic bags to collect the waste. They are expensive and are a pain to swap out. I want a cyclone to seperate a majority of the waste before it ever gets to the filter.

[Albert Lee]

thank you all... I've bought a second hand baghouse extractor similar to the Dantherm for about $900 USD this afternoon, its pure fluke, I have been keeping an eye out on these dust extractors for awhile now and they are seldom available. Included in the package are:
45 feet of 10inch spiral duct
3 x 90 degrees bend
250-150 reduction
1 x Y junction
22 feet of 6inch spiral duct and bits & pieces...

I think the ducting along could cost close to $500USD in NZ...


Its a 5hp, 3 phase unit, inlet is 10 inch, the manufacturer's spec states 5470CFM. but I am assuming thats taken with no static pressure.

The unit is about 10 feet high by 3 feet wide by 8 feet long.

by the way its the one at the front, not the shiny one at the back.... :rolleyes::rolleyes:

[Michael W. Clark]

I think you did good Albert.

Take a look at the material used for the collection bags. May want to upgrade to drums or plastic bags eventually.

[Albert Lee]

after a full days work, the baghouse extractor is finally in the garage. I've put them on wheels temporarily so I can shift them around in the garage.

Albert,

Wide angle lenses are deceiving but will the filter bags fit on top and clear the ceiling?

[Albert Lee]

Hi Jim, not really.. the ceiling height is 9', the unit is 10'2" high, the filter bags hangs off a steel frame and the steel frame is supported by 4 individual steel pipes, I am going to get shorter steel pipes to use temporarily... not ideal but there is not a lot I can do really, unless I place the unit outdoor but that will involve a lot of work including sheet metal canopy, some sort of concrete foundation, ducting... I probably will do this eventually but for the time being, the extractor will stay in door.
