Jds cyclone

[Jack]

I just set up a Jds 3hp cyclone if anyone is interested in the first tests connected to my 4" pvc S&D pipining.

Absolutely. I'm looking at one for my home shop.

[Chris Friesen]

Certainly.

My main concern with the JDS unit at this point is the surface area of the filter. It's only about 68 sq ft.

The "standard" set of filters suggested by Bill Pentz is a pair of Wynn Environmental filters, for a total filter area of 600 sq ft.

I've asked JDS for any comments they might have.

The JDS has a different fan design (it looks like welded S/S, 15" dia., top plate over blades and another plate below the blade (welded to blades) that is tapered from intake to exhaust side. The bottom plate has a large entrance hole for the entering air. There is a large chamber at the exhaust of the fan instead of piping. For a test I have

30 ft of 4" pvc (fed from cyclone with 10 ft of 4" plastic flex pipe bent in a 'U' shape, through 10 bends to a cabinet saw, and an 8" jointer ( jointer feeds a trashcan cyclone with another 20 ft of 4" plastic flex hose, can't waste the JDS clear plastic bags). At the tablesaw ripping on edge to make dust , little escapes. The jointer has no chips or dust, and I connect the trashcan cyclone (at the end of all this pipig to my router table fence 2 1/2" port (reduced from 4" ) no chips or dust escapes that I can see (if using a backer board). This machine really sucks. The 4" piping I'm using now will be replaced with at least 6". Motor amps using this 4" piping set-up = 12.8, motor full load amp= 18 . My old dust collector was a g1029z grizzly which with only one blast gate open had 1/2 the suction as thi does with 3 open. Installing 6" -7" should bring the collector to max cfm. Jack

If the blower doesn't move air at higher static pressure more filter area is needed.
