Table saw dust collection splitter

[HexusOdy]

Hi guys,

I have a TS with a 4" dust port int he cabinet and a 1 1/2" port on the crown guard. Is there a splitter available that will enable me to connect both to one 4" dust extractor?

I'm not sure it's 100% what you want, but Axminster do a part that allows that kind of connection.
Sorry can't provide a direct link, limitations of my device. It's number is 502568.

Hi - Before you spend time trying to find a suitable connector you will need to ensure you have enough suction i.e a powerful enough extractor. Serving two ports at once will need a minimum of a 1.5 HP extractor. A smal shop vac hooked up to the saw will not pull all the dust away.

If you have a small extractor I would concentrate on the top crown guard port as this is where the dangerous air borne dust will come from. The dust falling to the bottom where the 4 " port is will just collect at the base and can be cleaned out at the end of the day. I have a 2HP extractor and even that will not extract the dust falling to the bottom, unless you have a dust collection shroud around the base of the blade housing much like the US style powermatic saw range.

However you may be able to rig something up from these to suit your needs

I do have a 1.5hp 4" chip extractor that should cope. Regarding the parts I thought there might be some kind of Y splitter available with a 100mm straight section with a 1 1/2" connector coming off the Y.

I suppose I can get a normal 100mm Y splitter and then put a reducer on the Y.

My saw has a connection from its 4" outlet to the blade guard. Fairly low powered dust/chip extractor extracts the chips OK, one of these but different badge - http://www.axminster.co.uk/axminster-ho ... tor-501262 but, if I blow smoke at the blade guard, none is sucked in. I now use Karcher shop vac directly to the guard when cutting mdf.

This is probably what you want. http://www.axminster.co.uk/axminster-du ... 0mm-502568

Forgive any ignorance displayed here, but I didn't think you were supposed to reduce the size of the hose used on a chip extractor(HVLP), as opposed to a shop vac (HPLV) where you could? Or is it the case that because there would be a 1 1/2 inch and a 4 inch being used at the same time it is OK?

At low pressures air doesn't compress well, so indeed, running a HVLP extractor through a reducer will tend to kill airflow quite badly. That said, the 4" -> 2 1/2" + 1" splitter for my Axminster TS200 works OK from a HVLP system. However, I find it's much better to connect the shop vac to the smaller port (on the saw guard).

HexusOdy - don't overlook DIY stores. There's plenty of 4" drain pipe, plus connector rings (sometimes in the bathroom department for extractor fans), and also 1 1/2" pipe. It's not that much work to make a section of 4" with a 1 1/2" going off at 45 degrees (i.e. make your own adapter).

You don't need to make your own adapter if you don't want to ad they are easily available to accept std 40mm plumbing pipe. Most common either glue into or clamp on to a 110mm soil pipe and not difficult to seal ont a 100mm or even 75mm rainwater downpipe.

They're all 90 degree connections to the main pipe though? Not the end of the world, but it's generally more efficient if the branch goes off at a shallower angle (e.g. 45 degrees).
