Forum Members,

I recently purchased the Hammer N4400 band saw and the Hammer A3-31 12 inch jointer planer combination machine – they are great!

I was using a 1 hp Grizzly portable dust collector – that was no longer sufficient.

So, I built a box, took off the inlet cover, mounted the motor on the box and mounted a 4 inch inlet on the side of the box.

Here’s my problem: when the grizzly dust bag is off (just to check suction) the power seems very strong. When I attach the bag, which captures only big particles, suction falls in half.

Would buying a cyclone help? What type of filter would be better for cleaning the exhaust and maintaining the highest CFM?

Thanks,

Chris

it’s normal that suction is greater with no filter bag, it takes alot of energy to push the air through.
i think that a cyclone will possibly decrease the suction even more, anything you add to the system makes the flow drop. a bigger filter bag could help.

Hi Greedo,

That’s what I was thinking. I plan to try a larger filter bag – the impact of a cyclone was unclear to me.

Have you seen the new portable Grizzly dust collector with cyclone? Any experience with it?

Thanks,

Chris
