What are the different types of sandblasters?
Gravity feed sandblasters include a container called a hopper. This hopper carries the blaster media and is attached to the top of the gun. When the blaster is turned on, the air bursts out of the air nozzle, and the pull of gravity releases the blaster media alongside the air steam. These types of blasters usually come in handheld gun forms and are handy if you’re looking for a low- maintenance option.
These types of sandblasters consist of large, pressurized canisters that are filled to the brim with the abrasive materials of your choice. When the trigger is turned on, the abrasive media and air pass through a single hole, out into the open. Not only is this one of the most common mediums for cleaning purposes, but it is also ideal for anyone looking to renew surfaces like glass, stones, and much more. Besides being relatively low-maintenance, pressure sandblasters are also the signature models for high-pressure cleaning and stain removal. Since the abrasive material cannot be reused after a round of operation, it does make this particular version comparatively more expensive. However, these blasters are incredibly foolproof and user-friendly despite the initial investment.
Siphon sandblasters form a vacuum using the compressed air force. This vacuum pulls the abrasive material into the barrel via a hose. Besides being substantially durable and sturdy, these sandblaster models are also one of the most cost-effective ones in the market. However, since the blasters’ system produces relatively slow results, it may take longer to complete a large-scale project.
Factors to consider before purchasing a sandblaster
Size and Construction
Ideally, you should try to get your hands on a sandblaster that is compact and more on the portable side, as opposed to a bulkier model. Considering sandblasters are handheld tools, it’s essential that they be lightweight and easy to hold and carry around. For this reason, it is generally more practical to invest your money into a more small-scale and condensed variety that you won’t get tired of carrying.
The air compressor of your machine ought to have a minimum flow value. You’ll spot sandblasters with differing airflow ratings, ranging from around seven CFM (cubic feet per minute) all the way up to a twelve CFM airflow.
When deducing which sandblaster to buy, consider the pressure rating first. Your future blast compressor should have a particular air pressure level to work efficiently. Some sandblasters offer a range of air pressure ratings, for example, 60-120PSI, while others are less flexible and only provide a single rating of 90PSI.
You may need to limit your options depending on your budget and the purpose for which you require a sandblaster. For example, if you’re looking for a blast machine to execute less substantial and small-scale projects, then these types of models will generally cost you less compared to industrial breeds. The same applies to domestic and household sandblasting machines that are normally used to conduct various DIY projects and other similar ventures.
What are the different types of blasting materials?
Similar to the varying shapes and sizes, the blasting media also comes in a variety of options to choose from. Not only do you need to consider the grit size of your abrasive material, but you should also investigate the diverse individual qualities of different mediums to find one that’s the perfect candidate for your job. Keep reading to get an insight into the various different types of blaster media for an optimal blasting experience.
