what size air compressor is the best for sandblasting?

The best size air compressor for sandblasting depends on the size of your sandblast nozzle. Determining the size of the nozzle most often helps to understand the perfect size air compressor for sandblasting. Maintaining constant pressure with your sandblaster will enable the most efficient cost of blasting your items. The lower the cfm (cubic foot per minute) the longer it takes to remove paint, rust or general cleaning from the surface. With a smaller size air compressor the pressure at the nozzle will constantly drop until the point where the air compressor can only maintain the maximum amount of pressure that the air compressor puts out.

Screw air compressors are most commonly the better types of air compressors to use when sandblasting as they are able to keep a constant cfm air flow. Screw compressors also are designed to work hard and not create any issues running hot or overloading. Piston compressors are designed to start and stop at least 4 times every hour and have a duty cycle. Piston machines are great for small to medium sandblasting operation whereas a screw machine is better for medium to large operation.

Sandblasting pressure blast pots work best with a dry air supply. Having an air dryer whether it is refrigerated or not allows clean fresh air to your blaster and avoids any types of blockages or condensation problems within your sandblast pot. When condensation (water) enters the sandblast pot it will create a blockage and limit the abrasive supply to a point where no abrasive can be produced to the blast hose & nozzle. If this happens you have to stop blasting, take the pot apart and clear the blockage and fix the condensation problem to start blasting again.

Listed below are the specifications on what size nozzle should be used with the size air compressor;

  • Nozzle 1/8″ 100 psi 21 cfm
  • Nozzle 3/16″ 100 psi 45 cfm
  • Nozzle 1/4″ 100 psi 80 cfm’
  • Nozzle 5/16″ 100 psi 142 cfm
  • Nozzle 3/8″ 100 psi 200 cfm

These specifications are based on sandblasting pressure pots usage and may vary depending on the size blast hose and air hose you are using. It is always the best rule to have more air when sandblasting than less to maintain a constant pressure at the nozzle to maximise your efficiency. Ublast Pty Ltd have all the correct specification available and we can help to make sure you have the right size equipment to sandblast your items.

what size air hose do i use with my air compressor

what size air hose do i use with my air compressor

The answer depends on your tolerance for air hose problems, what type of work you plan on doing with your air compressor and the air hose, and as always, your wallet. Is change in your compressor air hose worth it for you? What type of air hose do you use, pvc, rubber?

If your air compressor is a typical single phase then it will have the most efficient use with a 6mm to 10mm air hose. And also typically the length of the air hose should be no more than 30 metres to avoid any pressure drop.

What Size Air Compressor Do I Need?

what size air compressor do i need?

Depending whether you need an air compressor for commercial or residential needs, the air compressor should have a bigger free air delivery than the air tools you are using. An example could be you need to pump up truck tyres, you want to save money and purchase a small 240 volt compressor but in reality you need a 3 phase compressor. You can buy a single phase 240 volt compressor that pumps up to 140 psi instead of 115 psi.

There are many options when purchasing an air compressor, always ask a professional that sells compressors for the right advice on what type, size and brand of compressor you need.
