Hi,

I don’t yet have a vacuum system set-up, but was wondering if I took a 4” dust collection hose and ran it from my Dewalt DW735 planer to a large trash can, will the planer be able to push the wood chips into to the trash can without the aid of a vacuum? I know that the DW735 has a powerful blower on it, but don’t want to cause too much strain on it. What’s your thought? Thanks!

It should work if the hose is not too long or too many turns.

The short answer – yes. The long answer – yes but you will wind up with a lot of dust blowing out of the trash can unless you have some way to filter the air coming out of the can. I’m assuming there will be some sort of lid on the can with an inlet and outlet hole? Even a makeshift furnace filter over the outlet will help keep the dust down.

I emailed Dewalt and asked them for the 735 blower air flow:

Here’s their response:

Thank you for contacting us.

The information I received from the Product Manager is without the adaptor the CFM is 225, with the adaptor, 193 CFM. Unfortunately that’s all the information he provided, also stating he didn’t have any information concerning the discharge pressure.

I’m sorry not to be able to provide the information you are wanting.

In case this email does not fully answer your question, or you would like to contact us for any reason, simply reply to this email.

Thank you,
Jack

I have a dust collector attached to mine, so I can’t answer your question from personal experience. However, I do recall seeing a video on changing the knives on the planer and, in the background, the guy had a hose coming from the planer into what looked like a large pillow case, or some sort of large cloth bag.

You obviously can’t run it directly to a sealed can since that will block the air flow, but some sort of filter should work. I’m amazed at the amount of air that thing blows.

Watch the first 5 minutes of this video by Matthias Wandel. Shows your planer and what he found on dust collection.

I ran a board through mine once with no DC attached … once!
I’ve seen pictures of chip collection bins built into the bottom of the planer stand with a furnace filter on the opposite side to filter the outcoming air. You’d probably want a baffle inside to slow down the dust and keep it from blowing right at the filter.

You can run into a filter bag with the 735, but not straight into a trash can.
Trash can separator, then a filter… Yes.
Sealed trash can… No.

It would just pop the lid off, because all that air needs to go somewhere. On the rare occasion that I forget to turn my dust collector on, my 735 is still virtually spotless. It has enough fan power to throw the chips and dust 20 feet and up a vertical climb of 8 feet, through the cyclone.
