Need recommendations for an Air Compressor 4 sandblasting

If all the power available is 220/230 Volts, single-phase, the largest compressor you
can run is 10 H.P. That is a poor choice in the USA, as the motors draw a ton of
power and aren't all that reliable. They are also expensive.

A decent 1/4" sandblast nozzle consumes 85-100 CFM @ 90 PSIG, when new. As
it wears air use goes up. A 10 HP compressor makes 35-37 CFM. Unless you are
using a very small nozzle and extreme patience, you'd be better off renting a gas
or diesel compressor for your blasting project.

It is easy to ruin very expensive body panels if you're not well versed in the "art"
of blasting. Most people today use soda, plastic media or chemical stripping in lieu
of sandblasting on collector cars etc.

P.S. - My business is air compressors and sandblasting equipment.

 

What chemical strip do you recommend for removing paint and grime from aluminum?


Finding any other than sand blasking here in Germany is VERY difficult.

 

they may use sandblasting term in a general sense, but if you look deeper you will find that they are using different media ( other than sand ). It' s the same as adjusting the grit
level of sand paper for the task.

if this is a one time do it yourself project, take your car / parts to a facility that specializes
in blasting. There can be a steep learning curve in technique and learning the grit levels. The erosion damage while learning can be severe and is royal pain in the backside to repair. Perferations in the skin are not unusual while learning to control and use the correct media.

 

Rent a diesel powered screw compressor, it'll do the job.

 

Here are already good recommendations for air compressor and I will take them into consideration. I do not have an air compressor because I thought the devices are too expensive and so I simply use the air-compressor rental service which is cheap and convenient. Nevertheless if I find a cheap offer I will definitely buy one. Hopefully I will find the right offer for my requirements but actually I do not doubt that.

 

sandblasting places a severe load on a compressor. We use a 25 hp unit with a 250 gallon tank and its rated at 100 cfm. We can sandblast with a 100lb pot and the compressor will cycle. You must use a 1/2 inch hose from the compressor and the pot must also have 1/2 inch hose and fittings. Smaller hose cannot supply the needed air to replenish the pot.

Also, I was told years ago form the devilbiss repair people here in toronto that 1hp = 4 cfm.
If you use this ratio you can deterimine the actual hp compressor your buying.
