Sandblasting Equipment: Which Blast Cabinet System is Best for You?
Suction and pressure are the two main types of blast cabinet systems. These both systems have many advantages but understanding their differences is important in order to decide what type of sandblasting cabinet will be acquired. The frequency and duration of blasting operations per day, availability of compressed air and the objective of the blasting process are all important factors to take into consideration.
Suction Blast Cabinet
Suction-type blast cabinets suit most applications and are economical; they are ideal for low production operations, light duty cleaning and occasional maintenance jobs.
Benefits
- Lower initial cost: a suction blast cabinet costs less than a pressure blast cabinet
- Lower operating costs: blast media is being supplied by a suction action rather than being fed with pressure; the media will leave the blast nozzle at a lighter pressure and speed.
- Lower air volume requirements: needs less air to function compared to a pressure fed cabinet.
Cons
- Suction blast cabinets are limited in the types of media they can use; metallic media such as steel cannot be carried into the air stream.
- Slower production rates: a suction blast cabinet will supply media at a lower pressure and a reduced speed.
How Does a Suction Blast Cabinet Work?
A suction-blast gun has two hoses, one for air and one for media. When the gun is activated, compressed air is metered into the gun body by an air jet and projected out of the blast nozzle; this is where the vacuum (i.e. suction) is generated and pulls the media into the gun and propelled out to the surface to be blasted.
Pressure Blast Cabinet
Pressure blast cabinets provide faster cleaning rates and are much more powerful- they are used for larger volume applications and aggressive blast cleaning.
Benefits
- High Production: pressure blast cabinets are 3-4 times faster in cleaning a product surface than suction cabinets.
- Higher performance: as pressure blast cabinets provide media at a greater force, products will be cleaned at a greater degree.
- More aggressive operation
- Any type of media can be used.
Cons
- Greater initial expense: a pressure cabinet will cost more initially than a suction blast cabinet.
- Items such as blast nozzles, cabinet linings, and window covers will be more inclined to wear faster because the media will be moving at a higher force and speed compared to a suction blast cabinet.
- A higher volume of air is needed
How Pressure Blast Cabinet Works
In a pressure blast cabinet, a pressure vessel is used to store an amount of blast media at high pressure. When the media and air are released from the pot, it accelerates and picks up speed as it travels through the nozzle.
The pressure of the blast is controlled by a foot pedal and the abrasive metering valve is set to obtain the ideal media mix to maximize impact on the workpiece while keeping its consumption at its minimum.
A Word on Cabinet Quality
There is a wide range of cabinets available at a wide range of prices. Not all are created equally. Having handled so many second-hand blast cabinets over the years the engineers at Rileys can confirm quality has a huge impact on the performance and lifespan of blasting cabinets.
Blasting is an abrasive process, so it has an impact on the machinery as well as the parts you are blasting. Frankly cheap, riveted cabinets with cheap components from eBay don’t compare to welded cabinets with thoughtful design and quality components. Both approaches have their place in the market, but it is important to be honest about the capability you need versus the capability that can be delivered by a cabinet. At Riley Surface World, we have both pressure blast cabinets and suction blast cabinets to suit your desired needs.
