Bumping this up as I'm looking to pair either an Excel 1 or 5 with the clamping module.  @Kriss - any update on how the smaller and quieter Excel 1 worked out?

My thoughts: the excel 1 was louder than I expected (louder than the Festool pump), but I have no complaints regarding its suction capacity. My setup has the pump inside a closet and I run a hose out to the VAC-SYS - so the noise becomes a non-issue.

I haven't seen an excel 5 to compare. I'm happy with my excel 1 so ultimately I'm pretty sure you can't go wrong with either pump!

Thanks @Kriss!  Just out of curiosity, did you ever take a smartphone SPL meter (or real one) to it to see how it measured up to its advertised 45db?  I wonder if it's the pitch or if it specs higher. 

Haven't seen many vids from you lately.  Life getting in the way?   [tongue]

How would the Festool pump work with vacuum bags?  Is it practical to get away with one pump for both Vac Sys and vacuum bag use?

Which of the three pumps would be best for both uses?

The Festool pump is a continuous duty pump. Works just fine for vacuum bags.

Yes.

The Festool is (I believe) a 2 cfm pump, which would be totally fine for moderate sized vac bagging.  If you wanted to do larger vac bagging, I think the Excel 5 would be better.  If you look at veneersupplies.com, they have a chart comparing their systems, including the two continuous duty ones (Excel 1 and 5).  The Excel 1 is a 1cfm and supposedly can handle 4x4 bags (for flat work) and 2x4 curved.  The Excel 5 with 5cfm can do 4x15 or 6x10 flat and 4x6 curved.  So I would guess the Festool pump would spec somewhere in middle...

Oke, just tuned-in on this topic....

I work for a comany named Becker. we are the inventor of the rotory vane vacuum pump.
I'm the head of service and technical matter within Belgium Netherlands and Luxembourg....
But enough about me!

the deeper the vacuum level, mbar, the stronger the grip. This is correct. But.....
all leakage will drain your vacuum so piping and hose connection are important.

I noticed the remark, that oil lubricated pumps blow out oil... than you are dowing it wrong!!! oil circulation speeds up when vacuum levels is boulding up. oil lubricated pumps need to work on max. vacuum level. when the max vacuum level is NOT reached oil circulation and pump effort increase. the internal oilcircualtion system is not build for draining maxx oilflow and starts blowing exessive oil.  because of the oil, all components get a almost zero clearance so almost absolute vacuum can be reached.-0mbar ab. or 1000mbar rel.  perfect for what you want.

the use of a softstarter or frequencyconverter protects your pump against the kick-in of electicity. this will damage your pump within a year.

oil free pumps, not so deep vacuum level but for your use oke. so much to choose from.
the deeper the vacuum level, the less flow. sow check for this!

for both pumps, make sure a vacuum savety valve is installed in, or externall with your pump.
when the max. vacuum is reached, flow almost stops. this means no more cooling of your pump internal.
vacuum pumps create hot exhaustair, dust in woodindustry, hot running pumps and poor maintenace, do i need to mention..... so a hot running pump because pulluted filtration lack of flow sawdust and so on, check it.

Filtration, put a pre filter between the vacuum connection and this will als save your pump.

maintenacen is crucial, replace your filters on time, keep bearings lubricated and check pump internaly. prefenting damage.....
Any further question, let me know.

money..... what ever you want just be save. invest in what you can affort. Goog luck!!!
