Shaping Room Air Extractors

Hey all howsit?

can anybody out there tell me how far down you should filter air while sanding so you dont piss off your neighbors with a nice layer of resin dust on there cars. 40 microns 30?

Any light shed would be greatly appreciated.

Whether you’re shaping or sanding, the most efficient way is to use a vacuum line on the tool. Most planers have a port, and there are several sanders which have a vacuum system (Fein, Festool are a couple). Most of the tool vacuums (or even the better Shop-Vac/Rigid ones) will produce little or no dust in the exhaust if you keep the filters clean.

planing is no prob. most planers have a port.

but what about sanding? it has to be a “whole room” extractor system with a large wall mounted port and a large intake fan right?

cheers

It’s very difficult to use an extractor system due to the length of the board. You could use an extractor with a horizontal row of ports (spaced about 18" apart)on a stand at the board level. It is much more efficient to have the vacuum on the tool. Festool (www.festoolusa) and Fein have dustless sanders. The Festool (Rotex) is so dust-free that you can glosscoat next to where someone else is sanding. This a lot cheaper than a separate room with an extractor/intake setup.

hate to have to buy yet another sander but its worth a look. I tried www.festoolusa.com and could not locate.

I tried just festool.com and got to choose a country.

Oak, Festool uses independent sales people, and they’ll come to your place and let you try it. They let me sand a a hotcoat on a LB just to make sure I’d like it. I’ll warn you, they’re expensive ($700). The price scared the hell out of me (a Harbor Freight regular), but the performance and no dust really does justify the cost. Call 'em and try it; let me know what you think.

For our school surfboard design course , dustfree was an essential. Festool provided the best option .We gained advice from local panel beaters as the most rich source of R& D . The hitachi and dewalt planer outlet adaptors we purchased fit tight to the standard feestool rubber hose connections and the rolling overhead Gantry we designed has removed some of the initial frustrations ie. confusion with leads and hoses. For sanding we have a range of Festool sanders…but the most commonly used is a combination randon orbital/radial …can be switched easily to required mode…RPM is adjustable …for students fine … my own personal choice is outside with the sander polisher due to a lack of speed and torque… however I will experiment further with a range of differing diameter pads. Sorry this doesnt include tech details model no size, rpm etc but its labour day holiday today and thats work. We queried engineers designing facilities and he assured us that to extract by fan efficienty throughout the shaping and sanding process was outside our financial resources and even then questionable with efficiency. Ive seen specialised sanding room …best was a huge phlenum fan drawing to a muslin fallsheet and water to collect and dispose … yes if you are prepared to commit to investiagtion , second hand purchasing and installation… there are options … I will be interested to here and learn more about this issue as it is huge in terms of environmental safety.

well …o.k…I baught a festool ETS150/5EQ.

(about $300 with a couple of boxes of papers).

they let me try it in the store (the “japanese wood worker” in alameda)

on a skim board and it was great! not a spek of dust got away from the pad

and the speed adjustment was great. all I have to do now is figure out what

grits to use and i am sanding “dust free” without having to get a full room

dust extractor.(so happy)

cheers

p.s.

you should still wear a good filter mask “just in case”.

well my shaping room is a shed…and glassing, hotcoating, sanding…i cant afford a whatever extractor…i wear a good mask , and cover the room with all kinds of dust…and have to take a shower once and a while…the neighbors shouldnt be bothered because the dust stays in there,then i sweep up now and then and start over…but i guess if your in the market for an extractor , i guess youve allready been through this.
