What are the Best Air Compressors for Sandblasting?
Air compressors for sandblasters require a very large amount of air to push the medium. Some blasters use sand while others use glass beads which are blasted at a target.
The volume for air that is put forth is called standard cubic feet per minute (SCFM). This specific amount is a match between the equipment and the air compressor. This number is often found in the user manual of specific equipment. When you find this number you need to multiple it by 1.5 and this will give you the minimum SCFM’s necessary.
Compressors are available in oil and oil free versions. Since sandblasting requires so much power you want to look for a unit that is an oil version because it is better for this specific type of work. The oil is used for lubrication. Oiled machines last longer and suffer less wear and tear. This is because the oil keeps the internal parts cooler. Because of the type of use an oil-free compressor would become damaged quickly.
Remember sandblasting requires lots of power and you should always use an air compressor with at least a 2 horsepower motor. The more horsepower the less stress on the internal workings of an air compressor when it comes to this type of work. So higher horsepower longer life for the unit.
Sandblasting is usually done on site, like sandblasting of walls and even done in residential units at time. Portable compressors are preferable to stationary ones because of this. Portable units usually have wheels. You will also want to have a sturdy handle so it holds up longer.
Sandblasting can also involve blasting indoor work like vehicles prep or outdoor like working on a wall. Indoor work involves electrical power source. If you are working outdoors you can opt for a gas powered unit that could not be used inside because of the risk of fumes.
What to look at when buying an air compressor for sandblasting
When looking at an air compressors for sandblasting you want to take a few things into account. The main three things are air volume, lubrication type and horsepower. You also want to take into consideration if you want to be able to move this around the jobsite so portability will also need to be taken into account. You always need to take into consideration power source. Is this going to be used inside or outside and is there electrical availability?
