SAND BLASTING

Sandblasting is process of smoothing and cleaning a hard surface by forcing solid particles across that surface at high speeds using compressed air. There are two kinds of sandblasters: “Suction” / “Siphon”" & “Pressure” Blast Systems. There are two basic kinds of sand blasters: Blast Cabinets & Portable Blasters. Our project used the suction/siphon system in a blast cabinet.

Also known as abrasive blasting, sandblasting is a surface finishing process that uses an industrial spray gun to propel abrasive particles at a very high velocity against a chosen surface. A sandblasting machine is powered by an air compressor, which ejects sand (and other materials with the potential to be abrasive) out through a handheld nozzle.

A sandblasting system includes four basic components: the air source, the sandblasting cabinet, the dust collector, and the blasting media. The air source is usually bottle gas or an air compressor. The sandblasting cabinet holds the object being blasted, while the dust collector removes dust from the cabinet. The materials used in sandblasting, whether sand or not, are referred to as blast media.

Sandblasting can remove paint, rust, and residue from oxidation from materials quickly and efficiently. Sandblasting can also be used to change the condition of a metal's surface, such as through removing scratches or casting marks. Sandblasting as a cleaning method has been widely used for over a hundred years.

CHOOSE YOUR PRESSURE AND FLOW

Depending on the material and purpose, sandblasting can require different pressures or flows. Our compressors can adjust their pressure and flow, making them the right fit for every sandblasting application.

HIGH QUALITY OF AIR FOR MAXIMUM UPTIME

For sandblasting, the moisture of the air can increase the downtime and the oil can contaminate the blasting surface.

TOTAL COST OF OWNER SHIP

The design of our compressors is not only focused on sustainability. Total cost of ownership is impacted by performance, ease of use, service, efficiency, resale value... Our range of compressors ticks all the boxes.

WHAT IS THE SAND BLASTING PROCESS?

Also known as abrasive blasting, sandblasting is a surface finishing process that uses an industrial spray gun to propel abrasive particles at a very high velocity against a chosen surface. A sandblasting machine is powered by an air compressor, which ejects sand (and other materials with the potential to be abrasive) out through a handheld nozzle. The gritty, rough consistency of sand makes it the most popular medium for wearing away decayed, flaky, excess or unwanted material on a surface to change its texture. Its abrasive properties are used to create a smooth surface with fewer imperfections to achieve either a finish in itself, or the basis for further coating. Various other mixed media can be used for abrasive blasting projects, including aluminium oxide, glass beads, copper slag, walnut shells, powdered abrasives, and garnet. Sandblasting can be used to strip off old paint, rust and grease; roughen up or smooth out a surface; remove corrosion; clean tools; and enhance aesthetic value, to name a few. It is often used to either restore a surface to its original condition, or prepare it for refinishing and repair.

HOW TO CHOOSE THE RIGHT SAND BLASTING COMPRESSOR?

It is vital to choose a right compressor to get the job done efficiently. There are 3 parameters are critical: pressure, free air delivery and the quality of the compressed air.

3 PARAMETERS TO TAKE INTO ACCOUNT.
PRESSURE

Based on the material (wood, cement, steel) and the purpose (roughning, cleaning, surface hardening), sandblasting applications need a different pressure. 

Pressure is the power of compressed air. The higher the pressure, the more powerful the output. This also means that the recoilless will be higher, making the operator more easily tired. As for most things in life: balance is key. Also in the construction industry. For hard steel surface, 100 PSI offers the best balanced pressure, varying on the operator’s personal status. 

As the compressed air goes through the sandblasting machine and hoses, it causes a pressure drop and therefore less productivity. Normally, the sandblasting productivity will reduce 1.5% as the pressure reduces 1% based on 100 PSI. Keeping the nozzle pressure at the best balanced pressure, is key to achieve the best productivity. A pressure adjustable compressor in this case, will make this happen. 

2. FREE AIR DELIVERY

In sand blasting, all the compressed air will go through the nozzle. The nozzle’s size and working pressure will define the FAD consumption. Insufficient FAD will cause a lower working pressure of the nozzle and reduce the productivity.  Our PACE and technical technology will increase the FAD of the compressor as the pressure is reduced, which can better fit the FAD requirement of the sandblasting application.

3. AIR QUALITY

The quality of the air is always an important factor: both for the operator as for the application itself. The lesser the oil and moisture in the compressed air, the healthier it is for the operator. With sandblasting, moisture in the compressed air may cause the hose to be clogged, increasing the downtime. Presence of oil on the other hand may also contaminate the blasting surface. Our high performance aftertreatment, aftercooler, filter and reheater will guarantee you the highest quality of compressed air. 

Temperature, exposure to contaminants, such as moisture or oil, and the overall quality of the blast medium are some of the many other variables that are integral to establishing what compressor - and its treatments - are best.
