Cabinet or siphon? This is rarely talked about before buying a sandblaster!
A sandblaster in a car service can be real support in everyday work. It can also quickly turn out to be a piece of equipment that just stands there and gathers dust.
Before you start thinking about choosing a model, ask yourself a key (even fundamental!) question: “Cabinet or siphon?”
At first glance, they do the same thing. Both clean parts with a stream of abrasive.
The problem is that they are used in completely different ways.
In this article, we compare cabinet and siphon sandblasters in everyday car service work. We show which tasks make one type start to get in the way while the other genuinely makes the job easier, and which REDATS models suit specific applications.
Cabinet and siphon sandblasters – what are the real differences?
Choosing a sandblaster comes down to two things: how large the parts are and whether you need to move around with them. A cabinet sandblaster is your work center for small parts — everything happens inside a sealed chamber, so dust and abrasive stay inside and you keep your car service tidy.
If, however, you plan to refurbish large frames or structures, choose a siphon sandblaster. It works in an open space, giving you full freedom of movement and no limitations on the size of the parts being cleaned.
| Comparison area | Cabinet sandblaster | Siphon sandblaster |
| Work area | Enclosed chamber | Open car service space |
| Work organization | Working at the machine | Working around the part |
| Workstation cleanliness | Abrasive and dust stay inside the cabinet | Requires securing the work area |
| Part size | Limited by chamber size | No size limitations |
| Mobility | Fixed location in the car service | Can be moved and used “where needed” |
| Process control | Work in one controlled environment | Dependent on workstation conditions |
| Type of work | Calm, repetitive | Flexible, task-dependent |
At this point, it’s worth remembering one thing: these are not two versions of the same piece of equipment, but two different tools for different jobs.
Which type works better depends not on the sandblaster itself, but on what parts most often come into your car service and the conditions you work in.
In the next sections, we move on to specific applications.
When does a cabinet sandblaster make the most sense?
A cabinet sandblaster makes sense when sandblasting is done regularly on smaller parts and cleanliness, control, and repeatable results are more important than mobility.
In which situations does it work best?
- Cleaning small parts “in series”
When bolts, clamps, brackets, tools, or other small components regularly end up at the workstation and need to be cleaned quickly one after another.
- Preparing parts before painting or refurbishment
When a part is meant to go straight to painting, refurbishment, or assembly after sandblasting, and a uniform, repeatable finish is essential.
- Working in limited car service space
When workstations are close to each other and dust and abrasive “outside” start to interfere with other tasks.
REDATS expert advises:
“If you sandblast small parts several times a week, set the cabinet sandblaster permanently next to the workstation where you prepare parts for assembly or painting. Storing it away and setting it up each time only slows the work down.”
| Model | Best use case |
| REDATS SB-90 | When you mostly blast small parts and want a fixed, tidy workstation without taking up much space. |
| REDATS SB-220 | When sandblasting comes up more often and includes larger parts that still fit inside the cabinet. |
When is a siphon sandblaster the better choice?
A siphon sandblaster is the best solution when you need mobility and plan to clean large parts. It works wherever the size of the components rules out using a cabinet.
In which situations does a siphon sandblaster make the most sense?
- Large parts and structures
Ideal for cleaning frames, profiles, and components that do not fit inside a cabinet chamber.
- High mobility
Allows you to take the equipment directly to the part, instead of moving heavy components to the machine.
- On-site work
Enables sandblasting in different areas of the car service, depending on current needs.
REDATS expert advises:
“With large parts, don’t struggle with moving them to the machine. Use a siphon sandblaster, go to where the part is, secure the work area, and get the job done on site.”
Recommended REDATS models – when each makes sense
| Model | Best use case |
| REDATS SB-17 | For lighter, quick jobs and where mobility and easy repositioning of the equipment matter. |
| REDATS SB-32 | When you want to work longer without constantly refilling abrasive, but still keep it handy. |
| REDATS SB-63 | For regular sandblasting of larger parts and working with a larger amount of abrasive. |
The most common mistakes when choosing a sandblaster
The biggest mistake when buying a sandblaster is failing to match its type to the actual work being done. Problems with the equipment usually don’t come from breakdowns, but from incorrectly assessing the car service’s needs.
What mistakes should you avoid when choosing a sandblaster?
- Buying a cabinet “just in case” without measuring parts
A cabinet sandblaster limits you by chamber size — if a part doesn’t fit, the machine becomes useless.
- Using a siphon model for small details
Choosing a siphon sandblaster for small parts means harder process control and the need for time-consuming cleanup of the workstation.
- Ignoring compressor capacity
Even the best sandblaster won’t work properly without adequate air supply. Poor air parameters make the equipment seem underpowered.
- Underestimating frequency of use
Equipment for occasional work is different from machines designed for daily, intensive sandblasting.
Summary
Choosing the right sandblaster depends entirely on the specifics of your work and the type of parts you refurbish. There is no single universal solution, so match the equipment to your real car service needs.
Which sandblaster will be better for you?
Choose a cabinet model if you focus on precision, perfect cleanliness, and regularly clean small parts.
Choose a siphon model if you need mobility, work with large parts, and require flexibility at the workstation.

FAQ – most common questions
1. Is one sandblaster enough for all tasks?
Not always, because cabinet and siphon models solve completely different car service problems. The choice depends on whether mobility or working in a clean, enclosed environment is your priority, as well as on the size of the parts you clean.
2. Does a siphon sandblaster create a mess in the car service?
Yes. Siphon sandblasting generates dust and spreads abrasive because the work is done in an open space. Using this type of equipment requires securing the work area beforehand.
3. Can large parts be cleaned in a cabinet sandblaster?
A cabinet sandblaster can only clean parts that fit inside its chamber. For larger components, such as frames or profiles, a cabinet is no longer a practical solution.
4. Does a sandblaster require a powerful compressor?
Yes. Both types of sandblasters require a solid air supply to work effectively. A weak compressor reduces working comfort and makes the cleaning result much worse.
5. Is sandblasting safe for aluminum and delicate parts?
Yes, but cleaning delicate surfaces requires a high level of process control. In such cases, a cabinet sandblaster provides more predictable results than working in the open.
