If there is no dust whatsoever is coming out the blower exhaust does this mean not enough CFM’s for the cyclone?

Reason I’m asking is I think I need to upgrade my blower. I have a super Dust Deputy cyclone with a Jet 1100 1 1/2HP motor/blower. It is collecting a 20” planer, and 8” jointer, 18” BS, 16” Drum sander (not well, though) but they are all clustered within 10 feet of the DC. I’m running 6” pipe with 4” drops to the machines.

This company carries a 3.5HP/1700CFM and a 2.5/1450 unit. He will sell me just the blower/motor. After asking me about my system he recommended just a 2HP 1350 CFM rated blower which in my mind is not enough diff from what I’ve already got. He said the 5HP units Pentz recommends is overkill for a most hobby shops

In the meantime, I’ve found a Blue Tornado 3HP cyclone units on CO asking $275.

So now I’m thinking if I can pick up this unit (what have I got to lose?) and see what it will do?

What you guys think?

Hi there! Bill Pentz really knows his onions, but that said, I’d agree that 5Hp is way too much for a small shop. That said if you’ve got a 20” planer and you’re taking heavy passes, 5Hp could be just what you need! My advice is install more suction than what you actually need due to pressure drops in pipes, leakage etc. If you can afford the 3.5Hp 1700cfm unit then go for it. I’ve just upgraded from 3Hp to 7Hp and I’ve only got a 12” Planer Thicknesser.
A really good cyclone will take pretty much every spec of dust out of the air if it’s working within the right parameters. I’m using a 16” diameter cyclone, and I’m sorry but being British, I’ve no idea what size a Dust Deputy is, so I can’t help you on that I’m afraid!

Just your drum sander will warrant the need for something with a lot more cfm capacity.
I tried a HF 2hp dust collector and didn’t even come close to being able to pick up the dust from that.

As for what you can get for the $275, that doesn’t sound like a bad deal at all.
Whether you get the 5hp or this one, you’ll need to make sure you run 6” ducting to all your tools and hoses.
Modifying your ports to handle the volume flow is very important.

I have a 5hp clearvue cyclone but work got in the way and I’ve only been able to get things set up but not completely.
I’m hoping this will take care of my needs since I live in 110-120 degree weather and would prefer not to have doors open in my shop to blow out the dust.

Have your say...
