Hi there, I just bought a Delta TP305 thickness planer, about a month ago, and I was amazed by how quiet it was
(in my opinion). Anyways, what also amazed me was the amount of chips that came out, WOW. (My first Planer). Well in my shop I like to destroy as much dust as I can , and direct it to the dust collector. So I coughed up the money and bought a dust chute for it. ($ 30.00 with shipping). Anyways the dust chute was amazing it collected everything and all went to my dust collector, and I was impressed. One thing that disturbed me was the the increased loudness of the planer, it’s this very low sound that just gets you. ( I almost had heart attack, planer 5 boards.)
Is this a common problem with dust collection on planers????

Thanks, Michael Frey

As a precusor question how much are you taking off the board per pass? It is possible the chips being pulled back through the back, instead of being ejected out the front are bunching up on their way out of the chute.

So today I planed some boards, and looked at the air flow, it must just be the way the planer is made, but man it’s loud. The Dust chute does a great job.

Thanks for the input.

My DW 733 planner is, without question, the loudest machine in my shop. I always use it with a dust collector and I can never hear the dust collector when the planer is running.

I always use ear protection with my planer.

I also find that the dust chute captures virtually everything. It’s quite amazing.

I can’t say whether it is louder – I always wear hearing protection. Believe me – I used to go by the saying, “if the music is too loud, you are too old.” After years of not wearing hearing protection, I have a constant ringing in my ears. But I still wear hearing protection.

But, back to your question. I had a 12” Delta, then purchased a 18” Woodmaster. In both cases, having the dust collector on is going to increase the overall noise in the shop. Is your DC attached to a wall in some way? The vibration would account for a low-pitch noise.

I have a 6” bench jointer that has a very noticeably different sound when connected to my ship vac. I would guess on the jointer alone the sound increases by 20 or 25 decibels. This is before I start passing wood through it. I’ve never run wood over the jointer without the vacuum on, so I can’t compare that.

The blades “cutting” through the air have a very distinctive sound, that you can usually differentiate from the sound of the motor. I always thought the increase in the sound was due to the increase in the velocity of the air across the blades.

However, I would be concerned if someone with the same model doesn’t experience this.

I work for a jet engine manufacturer, I’ll have to ask one of the aero guys what is actually going on.

mine doesn’t make more noise with the dust collector on, but then my collector is a bit underpowered.
what i did notice is that when i connect my festool vac to my little green bosch palmsander, that it makes quite more noise. doesn’t happen with my profesional bosch tools though, who i guess are designed not to make additional noise with a vac connected.

Could it be that the DC piping is acting like a resonator (like the body of a guitar) amplifying the vibration normally coming off the planer? If you have hard ducted it you may want to put in some flex hose to dampen the noise.

I will say that If I turn my planer on first, and then open the blast gate, the pitch of the sound definitely increases, quite a bit actually. In response to Mark, we have about 3 feet of flex hose in between the planer and the hard steel ducting, although most of your theory can still be correct.

Dust collection or not, I still hate the sound of my planer, but love the work it does.

My 13” Rockwell is definitely louder when I turn on my Dust Collector. I always use hearing protection when planing. It is very loud.
