US dust collector to 120mm euro port?
hi, i’m expecting to install a felder cf741p combination machine in the next few weeks, and i have a dust collection question. my current DC is a 1.5hp delta 50-850 with the dual 4″ inlet Y-fitting, ostensibly over a 6″ inlet (perhaps with a 4″ restrictor plate). i hooked it up to my unisaw and worked happily away for the last several years. but, the felder (which replaces the unisaw) has 120mm (~5″) ports. so, i’m left with a choice. clearly the easy (and poor) solution is to run the 4″ hose up to a 100mm x 120mm reducer hooked to a felder dust port. a better solution might be to pull the Y-adapter off the DC and try to run a 6″ hose up to the machine, and then reduce down to 120mm — assuming there’s enough flange on the underlying 6″ inlet to get a connector onto it. (a third solution is to replace the DC, but although i’ve bought the felder used, there’s not enough budget left over to replace the DC — that’ll have to wait.) has anyone had any experience hooking a portable US dust collector to a european 120mm dust port? many thanks for your help, bert

Oneida might be able to help you out. Give them a call.

I have a Hammer saw/shaper that has a 120mm dust port. I do not have dust collection yet but plan to run 5" duct to the machine. In your case I would go with the 6" hose/duct and use a reducer at the machine. A 6" to 5" Fernco coupling would probably work for you, 5" is about 1/4" larger than 120mm. The Fernco couplings are rubber and available at the big box stores. Most cyclone makers recommend running 5" or 6" duct off the main line and then use a reducer at the machine. I know you do not have a cyclone but the same rules should apply.

hi jerry,
thanks for the response. i'm thinking the 6" hose is a better idea as well. i've read that a number of people have "shimmed" the 120mm port with duct tape until they got a tight fit with a 5" coupler, so that's probably where i'll start. ultimately, i think i'm going to want to upgrade to a cycle like the oneida portable.

if it's worth doing at all, then it's worth doing well.
I assume you use your DC with other machines using 4"? If you want to optimize your flow, a custom box with a 120mm and a 100mm outlet would be best. Any HVAC place could make this, just make sure to be clear the air flow you are dealing with otherwise you could end up with 30g tin. The easiest is the 120/100 adapter they sell. I used this with my hammer j/p for a while without sacrificing cut quality. If your DC is close, it may suffice until you can go to a cyclone or a felder 125/160. Did you get all the transitions you need? To get the shaper/jointer and saw hooked up you will need some 90s and the 120/120/80 box to transition to the 50mm sawblade oulet. You probably have a 120 on the j/p, two 120 on the saw/shaper and a 50 off the blade. I went to a cyclone shortly after starting into the Euro tools, and have left on 100mm port for my bandsaw. Are you a member of the Felder Online Group (FOG yahoo group) yet, if not, many very helpful people there, plus they have negotiated some savings at some stores for members.

hi brad,
yes, my other machines have had 4". i'm replacing the jointer, planer, and unisaw with the felder combo, but that will leave my bandsaw and router table. those should be easy enough to "convert" to 120mm, if need be.i've been thinking of getting the felder divider box (120/120/80) and using it as the junction to the dual port use for shaper and saw. (saw ports: 120 cab, 50 guard; shaper: 120 fence, 80 cab; jointer/planer: 120). i figured i'd get a 6" hose to go to the box outlet via a 6x5 reducer like the fernco, then run 120/80 hoses off the divider box to the ports (with 80/50 reducer on the guard), with a straight quick connect on the 80mm hose, and an elbow quick-connect on the 120mm hose. i like the idea of the felder RL125/160 DC's, but they're probably out of my budget for awhile. ultimately, i think i'll end up with the oneida portable cyclone (with HEPA filter). i'm working in 3/4 of a 2 car garage, and it's already tight...i've been a member of the FOG for a few months, and have gotten lots of excellent advice already -- i don't think i would have bought the combo without the FOG -- and i have david best's survival guide.merry Christmas,

Chops:
I have the same Felder machine as you. As another poster suggested, Oneida carries a 120mm converter. I run a six inch flexible hose to the Felder splitter box and there is a 6" to 120mm reducer supplied by Oneida.
I really enjoy my Felder - make sure you join the Felder Owners Group on Yahoo. And get David Best's survival manual - you'll need it!
Good luck,

I cut the millimeter-sized ports off my European machines, and substitute inch-sized ones. You're always going to using inch-sized ducting, so why mess with the metric port at all?
hi jamie,
thanks for the response. i've thought about "re-plumbing" to US standard, but the size difference between 120mm and 5" is only around 1/4" anyway. most US stuff seems to use 4" as "the standard" (my other tools do). did you go with 4" ports on the euro-tools?since my shop is so small (3/4 of a 2 car garage), i don't have the room to run a duct system, so i'm going to be based off a portable collector. probably eventually upgrade to the oneida portable cyclone... when you substituted inch-sized ports, did you go with plastic or metal?
merry Christmas,

I put 5" ports on my bandsaw and jointer/planer. My connection to them is a piece of 6" hose with a 6"/5" reducer at the tip. The main ducting is 6" metal, running to a 2 hp cyclone. The jointer/planer's port has two different positions, depending on whether it is being a jointer or a planer, so flex hose seems the good solution. Except for the flex hose, everything else is standard HVAC metal duct from the local HD. There are many folks who say that fancy and expensive duct from the cyclone manufacturer is the only way to go, but I've found that the regular HVAC stuff works just fine. It is also readily available; when you need just one more elbow, it is a ten-minute trip, not a two-week wait.
