I have a Jet DC-1100 with 1.5 hp blower and use a 6 inch hose that is 5.5 feet long with a 4 inch reducer that hooks to the tool port. I also use it for a single tool at a time.
I am considering upgrading to the Clearvue and would use the same practice. But if I am maintaining at least 800 cfm (per Michael Standish’s observations in FWW article) at the tool with this practice, is there any advantage with 1000 cfm or greater?
Really need some advice in deciding on this purchase,
Brian

It depends on you. I have 1300 CFM and it doesn't keep up with my 20 inch planner unless I am really slow or make extremely light cuts. It's fine for everything else.. (while it can be marginal when using my 3 hp shaper and really hogging off everything with a big cutter in a single pass)..
Now top be fair I really hog off a lot per pass with my planner and have it going as fast as It can go. It fills up a 30 gallon trash barrel in less than 15 minutes.
bmyyou,
If at all possible, enlarge the 4" port on your bigger machines to a 6" port. Even the Clearvue will have a hard time moving 800 CFM through a 4" port. You need the larger port to provide the airflow to keep the chips moving uphill in the 6" line.
4" should be fine for jointer or drill press, but tablesaws, larger bandsaws, chopsaw hoods, radial saw hoods, all want 6" ports.
Planers over 13" wide benefit from larger ports, too. The Chiu Ting 20" that I bought from Grizzly many years ago (same model Frenchy uses) had a 5" port and it collected the chips very well after fine-tuning the chip deflector, etc. I had a 3 hp cyclone sucking only the planer when it was running, however.

Bill,
You are absolutely correct that you can tune up the planner on a grizzly to improve chip flow but 1300 CFM is still too small. Your 3 HP was probably putting out close to twice the CFM mine was..
MY chip production amounts to yards of shavings. Cubic yards at a time..
Frenchy,I totally agree with you. My 3hp cyclone was an industrial model rated at 1800 CFM @ 8" static pressure. Those other collectors are rated at 0" static pressure, a "whole 'nother animal."I know about the shavings volume. I used to plane tons of red oak 13" wide. We had to stop planing every 10 minutes to empty the 55 gallon drum, which took 2 men. I agree that that 20" Grizzly is a workhorse for a bargain price. Unfortunately, I had to sell mine when I moved further west. If I still had it I'd put a Shelix head on it and a Wixey height gauge and be totally satisfied.Bill
Bill Amen to both of theose improvements, the question I keep asking myself is would I have bought it with those as they now sell them? increases the price to what other brands sell for and while I am now totally sold on Grizzly when I purchased mine I was stuck in low cost because I didn't think it would be durable..
