Pros and Cons of Pressure Blaster


Sandblasting cabinets perform a variety of operations like rust removal deburring, surface preparation for coating, scaling, and frosting.


Pressure Blasters, as one of the main types of abrasive blasting cabinets that exist on the market, play an important role in abrasive blasting. And there are also different voices for pressure blast cabinets. In this article, let us get to know the Pros and Cons of Pressure Blast Cabinets.


A pressure blast is to use a pressure cabinet or pot to pneumatically push the abrasive to the nozzle. With direct pressure, the abrasive has no delivery weight so it travels faster and faster inside the abrasive hose until it passes out the nozzle office.  


Pros of Pressure Blaster

1.     Increased productivity. The most attractive feature that every best pressure sandblaster provides and is known for is its high speed. Pressure blast pots are faster than siphon blasters because they cause blast media to impact the surface of a product with a lot more force. Generally, you will be able to clean surfaces about 3 to 4 times faster using pressure blasting as opposed to siphoning blasting /suction blasting.

2.     More aggressive force. The abrasive media delivering speed of pressure blast cabinets is twice those of siphon or suction blast cabinets. The increased force that media will impact the surface allows you to remove heavy and caked-on residue easier.

3.     Can be blasted with heavier media. Metallic blast media, like shot or steel grit, is not easily done in a traditional siphon blast cabinet. Pressure cabinets mix the air and blast media in a pressurized pot and expel the abrasive into the cabinet. With a siphon or suction blast cabinet, this is not easily done, as the media must fight gravity, and be drawn up through the blast hose. So, for shot blasting, it is better to use pressure blasters rather than siphon ones.

Cons of Pressure Blaster

1.       Initial setup expense is much higher. Pressure cabinets require more components than suction blast cabinets. And the setup is much more complicated. It requires investing more effort and time to get started with a pressure blast cabinet.

2.       Parts and components wear out faster due to wear and tear.  Universally, the components of pressure blasting machines wear out at a faster rate than suction blast cabinets as they deliver the media with greater force.

3.       Needs more air to operate. When abrasive blasting with more force, the consumption of pressurized air increases. It takes more air to operate a pressure cabinet than a suction blast cabinet.
