?

The exception may be the filter cleaning option for the RL units.

Indeed. Definitely the exception. The pulsed air cleaning system on the RL250 seems to take all the air it can get. I have a 17 CFM rotary compressor and a 400L receiver, kept between 100-140psi.

If the receiver happens to be near 140psi when the cleaning cycle kicks in, then the compressor does not have to supplement the receiver. Under 130psi, and enough air is used to require a receiver top up.?

Also, there is a distinct difference in the cleaning "power" of the RL cleaning system at high pressures versus lower pressures. This is anecdotal only, but the cleaning system is much louder (bang bang!) at those higher pressures.?

Without a big receiver, you're going to need a fairly biggish system to keep up with the RL250s air needs. IMHO.?

Warm regards,

David Lucky

They make a nice clean cut.?

I had a foot operated pull saw that was very nice under the table old old.?

Also an over the table pull saw fixed at 45 with air clamps that was great for stoping glass German of course.

Seems like the 4hr 20 gallon California Air?unit is more than enough for me.

Guy's,

I should of mentioned in the original post my extraction is a small Felder AF16.(I have limited power now and in the future my shop will be moved to my olive farm which is off grid, so even less power)?

My main line is approximately 6 meters long

?,and the sander will be on the end of it, so I'm thinking of changing that drop from 125 to 160mm and then going with the 2 x 100mm flex that Mac suggested.?

Mac had mentioned the possible effect that flex had the effect of reducing flow about 10 to 1. Now I believe that is the standard response from ducting designers but in my tests I found very little difference between 6" solid and 6" flex. Now to qualify the flex I'm using isn't deeply ridged.?

well the information one would need to calculate anything: air flow in
CFM and the inches of Mercury that your system will draw are not there,
so you are going seat of the pants all the way.

Anecdotally I can say that I have an RL 160 with 25 feet of 5" Nordfab
duct with two 90 degree ells reduced to 10 feet of 5" duct with two
more ells reduced to 4" with one 90 degree and then out of the 4" blast
gate and then almost 20 feet of 6" spiral flex hose to a shop floor
sweep at the end of another 4 feet of steel 4"

That's a lot of bends and ducting and spiral flex and the floor sweep
still aggressively sucks up everything in its path

Meanwhile I have a 4 foot wide drum sander that is marvelously handled
by a 4" main off the 6" line and at the end of a length of 10" length
of flex hose
The reason for the 10 feet of 4" flex is - - - well - - - default. I
didn't feel like shortening the hose because I was still unsure of
machine placement and now I think I shall just leave it that way.

So I say: don't fear the reaper. Put a nice long hunk of flex on it
and be willing to trim as needed.

I'm about to hook up a drum sander in my shop.
The two top ports on the drum sander are 100mm
The sander needs to be mobile so tubing needs to be flexible (two pieces of flex both approx 2meters long)
My main duct is 160mm with drops at 125mm.
My question is do I go flexy 125 mm or 100mm to the machine.
Or any other suggestions?
Thanks in advance.

The original post was that it was all about noise reduction. ?It was after reading about Quincy and Kaeser and Cal Air Tools (here) that I purchased the Cal Air Tools 4HP 20 gal compressor with drier, and quiet operation was a consideration for me. ?

I am very happy with it so far. ?It is very quiet. ?I was thinking around the time of purchase that if I wanted it to be even more quiet I could build an enclosure that offered some soundproofing while allowing appropriate air flow, but now that I have the unit, I have not found the need.
