Hi

Can anyone recommend a quality air DA sander (with dust extraction)? I have a 3hp, 90litre 14cfm compressor. I was using a Clarke DA sander and that just doesn't budge when it touches a surface, or runs out of air which suggests it consumes a lot of air (although the book states 6cfm).

 

I plan on dry sanding epoxy primer.

 

Many thanks.

anyone know if this would be suitable and decent for my setup?

Good sanders with reasonable air useage are not cheap. The average cfm is not a good idea of useage as the average useage includes running and down time. I have a sealey one and my clarke industrial 3hp with 100 litre receiver keeps up but runs pretty constant if continually sanding, my sander states 4cfm but in constant use uses at least double that. I have now invested in an electric mirka ceros sander, not cheap but compared to running a compressor all the time and the noise of this and the sander thought it was a wise investment, to use an air da effectively you need a minimum 10mm hose dia and feed from a 1/2 bsp regulator, if you are coming from a 1/4 connection from the compressor then this will strangle it,

I don't think you will get a DA that will run well enough if at all for that set up.

 

Best to consider an electric one as a compressor to run one well will be very expensive.

I had one similar to that one from screwfix, the 125mm is a problem as most good quality automotive paper is 150mm, i used it for one car but burnt it out, ok if just the one job though. I then changed to an air sander and that was brilliant but very noisy which is why now I have bought a mirka ceros, cost almost £300 but very quiet and feels as good as an air da to use, but I do have 2 or 3 cars to do so was worth the investment. Think sealey do a 150mm da for about £70 just it's shaped similar to an angle grinder. I would advise using mirka abranet paper though it's a little more expensive but lasts really well. Try your air da with a direct connection from the tank with larger hose first as it may manage ok and have a good 1/2 regulator and set it at about 80psi.
