How much PSI does a sandblaster need?

Compressor Size and Efficiency You should use a tank with a minimum of 100 PSI for optimum efficiency with any abrasive sandblasting project. If you work with a lower PSI, you’ll add a significant amount of time to your project.

How much CFM do I need for sandblasting?

An air compressor which produces between 10CFM – 20 CFM is ideal for smaller sandblasting tasks. While a compressor which produces between 18CFM to 35 CFM is better for larger jobs where a more powerful experience is needed. While an industrial type of sandblasting needs a CFM of 50 – 100.

How many CFM do I need for blast cabinet?

8. As a general rule when cabinet blasting, use a small nozzle setup (4-8 cfm) for 3-5 HP single-stage compressors and then only plan on blasting on an intermittent basis (to allow proper cooling of the compressor).

How much air does a blast cabinet use?

Some companies supply abrasive blasting cabinets said to operate using a 120-volt air compressor, but these are normally using about 6 cfm. This is a very small gun size, but more important each different gun size produces different amounts of frictional heat at the same blasting pressure.

What air tools require the most CFM?

Continuous use tools need more air volume and therefore have a higher CFM requirement. A constantly spinning sander might have a CFM requirement of 8, (8 CFM @ 90 PSI for example), while a nail gun, which requires single bursts of air might have a lower CFM rating of 2.8.

How do you clean up after soda blasting?

A thorough pressure washing is necessary to remove the soda residue before ANY coatings or fillers are applied. This is very important; WATER is the only way to remove the baking soda. Do not try to remove it any other way, it will not work and you may experience a coating failure.

How big does a compressed air nozzle need to be?

(Chart for compressed air, nozzle size, and media consumption) –Using the chart below, if you want at least 90psi to sandblast, and your compressor’s horsepower is 17 or 74cfm, you can see that you can run a nozzle size of 1/4″ or smaller.

How much air is in a garnet blast nozzle?

Air Consumption (CFM) Per Blast Nozzle Using Garnet Abrasive Nozzle Size Nozzle Pressure Nozzle Pressure Nozzle Pressure Nozzle Pressure No. 5 5/16″ 89 103 214 No. 6 3/8″ 129 149 309 No. 7 7/16″ 176 203 422 No. 8 1/2″ 229 265 549

How many carbide nozzles do you need?

Evan says that you can go through up to 3 boxes of ceramic nozzles compared to using just one carbide nozzle; so it’s worth buying the carbide nozzles. How do I use the reference chart? (Chart for compressed air, nozzle size, and media consumption)

How is air consumption determined on a Hodge Clemco blast machine?

The consumption depends on the nozzle; it does not depend on the blast machine being used. The nozzle’s smallest internal bore can be determined using a Hodge Clemco orifice gauge, or by simply inserting a standard drill bit to match the internal bore size.
