Topic tags/keywords: dw735 chip discharge dust control question

Looks like I will building a capture system for this beast and was wondering. Does anyone use 2 1/2 hose instead of 4” with no ill effects.

The 735 has a fan assisted chip discharge, and throws out a BUNCH of chips. 4” will serve ya much better. I even use 4” on my 733.

I used a 2 1/2” hose on my Rigid planer with a reducer for over 10 years, sending the chips into a 15 gallon Rigid vac. Never had a problem save when the vacuum filled up, which happens way quicker than you might imagine. I would think you will generate about the same amount of chips per cut as I did.

Given the amount of chips a planer throws off the 4” will work much better.

thanks I guess I will make the trash can with a 4” input and make the vacuum side 2 1/2 inch. That will give me the best of both worlds. The output line will not be connected for the planer though, I think I will put a filter bag over the output just to capture dust that doesn’t fall to the bottom of the can.

Sometimes,If i forget to hit the remote to turn on the DC; the 735 has enough CFM all by itself to inflate the top bag of my DC through 10’ of 4” hose. You could likely just put a filter onto the output and save the electricity for the shop vac. Hehe, I’m always suprised when I shut down the planer and take off my earmuffs and realize the DC was off…again

For a dust collector use 4” with a drop out bin as close to the planer as possible.
For 2 or 2 1/2” pipe use a shop vacuum.

If using the dust collector the pipe from the paner to the drop out bin must be as short and as smooth as possible.

Many users have commented that a shop vac won’t keep up with the 735. I use a single stage 1 hp DC and it works fine.
Good luck.

I’ve never tried a shop vac and I stopped turning on my DC (4” hose) too. You don’t have to. The blower in the 735 is enough.

I have my shop vac hooked up to the trash can I built a separator for. I don’t turn it on, and the 735’s chip blower motor is enough to still blow the top of the shop vac up enough to shoot chips and stuff out if I forget to lock it down.

If you could go from 4’’ to 2 1/2 ’’ and get the same results the manufacture would have built and 2 1/2’’ outlet on the machine,.

My 735, seems to inflate my clear DC bag pretty well on its on. Many a time have I forgotten to turn the DC on. However, I’d look around on CL for a used DC. I picked up my old Delta for $150.
