Tilghman Rotoblast supplies blast pots (also called sandblasting pots or pressure blast machines) from Benoni, Gauteng. We offer 100 litre and 200 litre pots for normal dry blasting and for dust-reduced wet blasting, plus the hoses, nozzles, helmets and accessories that make up a complete portable blasting setup.
Because we also design blast rooms, wheel blasting machines and dust collectors, we can help you match the pot, nozzle, media and compressor to the job rather than just sell you a pot.

Blast pot sizes
| 100L blast pot | 200L blast pot | |
|---|---|---|
| Typical use | Smaller jobs, workshops, site work where the pot is moved often | Longer blasting runs, larger steel areas, blast rooms fed by one pot |
| Refills | More frequent | Fewer stops to refill |
| Versions | Dry blasting, or dust-reduced wet blasting | Dry blasting, or dust-reduced wet blasting |
Not sure which size suits you? Tell us what you are blasting, the media you use and your compressor size, and we will recommend a pot and nozzle combination.
Dry blasting and dust-reduced wet blasting
- Dry blast pots are the standard choice for steel preparation before painting, rust and mill-scale removal, and general cleaning, in a blast room or outdoors.
- Dust-reduced wet blast pots mix water with the abrasive to cut airborne dust sharply. They suit sites where dust is a problem: near other workers, in towns, or where cleanup must be kept to a minimum.
What makes up a blast pot setup
A blast pot is only one part of a working blasting system. A complete setup usually includes the parts below. Ask us for whichever you need:
- The pressure vessel (pot), 100L or 200L
- Metering valve, to control how much abrasive flows into the air stream
- Blast hose and couplings
- Blast nozzles, in a range of bore sizes to suit your compressor
- Remote control (deadman) handle, so blasting stops the moment the operator lets go
- Blast helmet and breathing air supply for the operator
- Moisture separator to keep compressed air dry so the abrasive flows freely
For replacement parts and blasting spares, Tilghman supplies them. Call 011 865 5770 or send us an enquiry.
Abrasives for your blast pot
We supply steel grit, steel shot and glass beads in 25kg bags, delivered across Gauteng. See blasting media for grades and advice on which media suits your blast pot and finish.
Need more than a portable pot?
If you blast every day, a fixed system usually pays for itself in media savings and operator time:
- Blasting booths and blast rooms with media recovery
- Wheel blasting machines for high-volume steel and castings
- Dust collectors to keep blast rooms clear
Blast pot FAQ
What size blast pot do I need?
A 100L pot suits smaller jobs and site work where the pot is moved often. A 200L pot holds more abrasive, so you stop to refill less often on larger jobs or in a blast room. The right size also depends on your nozzle size and compressor, which we can help you work out.
What is the difference between a blast pot and a sandblaster?
They are usually the same thing. A blast pot is a pressure vessel that feeds abrasive into compressed air and out through a nozzle. “Sandblaster” is the everyday name, although most industrial blasting now uses steel grit, steel shot, glass beads or other abrasives instead of sand.
What is a dustless or wet blast pot?
A wet blast pot adds water to the abrasive stream, which greatly reduces airborne dust. Tilghman offers dust-reduced wet versions of both the 100L and 200L pots.
What abrasive can I use in a blast pot?
Most dry abrasives work, including steel grit, steel shot and glass beads. The right choice depends on the surface and finish you need. We supply steel grit, steel shot and glass beads.
Do you supply blast pot spares?
Yes. Tilghman supplies nozzles, hoses, couplings, helmets and other blast pot and blasting spares.
