At Adendorff we stock various kinds of sandblasting tools & equipment. This short article will explain the different kinds sandblast equipment there is and some examples of the kinds of applications they are used for. We will also recommend the kind of air compressors recomended to be used with the tools mentioned.

The grit is kept inside the container where air pressure is created forcing the grit out through the hose. They come in various sizes and types. We also stock a “dust free” version that shields the spray area and vacuums up most of the excess dust created in the process. Once the grit leaves the container its sprayed onto the surface area of choice, however, the grit then is expelled to the environment and that has to be taken into consideration.

Benefits of Sandblast Pots

  • Covers large area surfaces and is a great time saver
  • Ideal for more commercial applications
  • The higher pressure used than in other smaller cabinet type systems, this means better penetration and rust removal.
  • more grit is moved compared to cabinets.

Cons of Sandblast Pots

  • The high rate of grit wastage due to grit being expelled into the environment
  • Potential health risks to a person in the immediate area (you must wear appropriate masks and safety equipment)
  • More waste means higher cost to blast surface area compared to cabinet systems

Pros and cons aside pots are very simple to use and very popular in the glass & aluminum industry. You will see these kinds of tools used in ship repair or restoration, its one of the best ways of removing rust from metal without losing too much steel in the process.

The cabinet is different to pots in the sense that it keeps the grit inside the cabinet itself. The grit is kept inside the bottom of the cabinet and circulated with the hose and gun. This means the grit is continually “recycled” until it becomes a super fine dust and has to be replaced in time. There is various kind of sizes and models available and most come with an internal light to make it very easy to see what you are doing.

Benefits of Sandblast Cabinets

  • recycles grit until it’s too fine to use, a great cost saver and better for the environment
  • great for finer smaller cleaning jobs such as car parts
  • no mess

Cons of Sandblast Cabinets

  • depending on the size of the cabinet, you usually have a small space to work with, and restricted weight of the object.
  • gloves and glass films get worn out over time and have to be replaced over time.

Cabinets are a mainstay in repair workshops especially when replacing a rusty part is more costly than a good cleaning. With various sizes available we have a type for any application in most workshops.

Sandblast guns that don’t use a container such as a pot or work inside a cabinet are very popular for smaller DIY jobs, especially for decorative applications on glass or aluminum. They work in a similar way sandblast pots do where the grot is simply forced through the hosing and onto the surface. Above there is a very unique “airbrush” sandblaster for superfine decorative applications. Sandblast guns are usually inexpensive and are ideal for the odd small job around the home or garage.

  • inexpensive and easy to use
  • great for small decorative work on glass & aluminum.
  • they have their own container or can extract grit from another container, this makes them very compact.

Sandblasting takes plenty of air flow at a high pressure of air. For the grit to the damage you need the particles need to travel at a high enough speed to cause friction on the surface you are cleaning. So even if you are using a small sandblast gun or a large pot you will need a larger compressor with a good duty cycle.

  • most guns or pots need a minimum of around 8 CFM or more. You can find this info easily from manufacturers we list this info on our entire compressor range
  • you need high pressure 4 – 6 bar or more, the most cost-effective compressors for this has a tank with a max pressure of 8 bar.
  • keep duty cycle in mind, think how long it will take you to clean the surfaces and how frequently you need to, for most applications a belt drive compressor is needed.

R 69,950.00

For compressors, you usually need to overshoot the CFM requirement by around 25% to make sure the air pump has some time to cool down between tasks. Sandblasting requirements allot of air so smaller DIY compressors fall short for this task. Petrol machines are popular for this application due to the excellent air flow the air pump generates with help form the powerful engine attached. They have smaller tanks but provide excellent air flow for the price and size.

    hi I am looking for a Machine to engrave/sandblast words into smalish pebble rock with a stencil – do you have a machine for this type of work

    • Francois Landsberg says:

      Hi, our pots should be able to do this pretty well since the rock probably won’t fit inside a cabinet. There are links above to our whole range of sandblasters.

  3. zano says:

    Please advise – what type of sandblasting equipment will I need for residential windows i.e sliding doors and standard size windows

    • Francois Landsberg says:

      It mobile work on site so a pot and a 200-liter belt driven machine. Cabinets are not an option here due to the large working area involved.

    • Francois Landsberg says:

      Hi, the v-type has a slightly lower running temperature however the single design (where the 2 cylinders are directly next to each other) have a better life time. CFM output is only marginally different. V-types tend to be slightly cheaper though. Honestly, the differences are very small but we usually recommend the singe design.

      The smaller direct drive machines have 1 cylinder and a much shorter duty cycle due to high RPM. These are recommended for DIY and home use.

  4. Joshua Dixon says:

    Good day, Would you recommend the COMPRV-230 200 Liter Belt Drive “VType” or the COMPRE-615
    200 Liter Belt Drive Compressor for a hobby workshop? I see the price difference is ~R200 so I am curious as to which is better/what the difference is. Thanks!

    • Francois Landsberg says:

      This is very hard to answer but the 615 model is arguably better. V-head does have a slightly higher CFM but it marginal. We recommend the 615 model it tends to last longer.

    Hello Francois. I would like to sand blast on drinking glasses and wine bottles to make decorative gifts.

    Would the following equipment suffice?
    COMPRE-001 (to be used for pin/staple gun as well)
    Not sure which gun to get. Thank you. Sherlyn

  7. Andre says:

    Hello Francois , I would like to sand blast pieces of deadwood on Bonsai trees to create a more naturalistic appearance with crevices and indentations , usually the wood is on its own but on some trees , I need to protect the live bark and foliage , so some of the nozzles must be pinpoint.. Trees not bigger than 100 cm and diameter around 25 cm. Once its done , I do not have to repeat the process . Can you recommend what type of equipment I need to do the job at home .? Thanks.

    • Francois Landsberg says:

      The only precision sandblaster we keep is like an airbrush gun but for sandblasting. But depends on how big of a surface. All these other guns you have to block off the parts you don’t want to blast by using tape or stencils.

      • Ryan says:

        Good Day.

        Is the vertical 100l compressor suitable for the bench type sand blast cabinet as well as air sanders etc? Do you possibly have a chart of what air tools are suitable for what compressor’s ?

        Thank you
        Kind Regards

        • Francois Landsberg says:

          Charting them is tricky since it depends on how long you planning on running them for. Essentially you want the tool to be 15% less CFM then what the air compressor supplies. Yes that compressor will be enough for intermittent use yes but it will eventually run out of the air to replenish.

  8. Sihle says:

    Hi would like to start sandblasting cars rather than using paint remover but I don’t know which size sandblasting pot would be sufficient for the job and the necessary tools I will need?

    • Francois Landsberg says:

      Both pots will have the same result. The amount of sand they keep is just different. If you have a small compressor maybe just get the smaller pot.

    • Francois Landsberg says:

      Yes and no. You can sandblast it has the pressure but at times you might have to wait for the machine. If you use the small airbrush type sandblaster that will be no problem. If you want to use a pot we recommend a 150-liter 2.2kw machine.

  9. dries brand says:

    Ek het saam met die “gravity feed sandblaster” n sak met materiaal gekoop waarvan die “grit” grote AGT 60 is. Voor ek die sak oopmaak sal ek wil weet of dit fyn genoeg sal wees vir die sproeipyp (nozzle). Kan jy help met die die “grit” gradering , dws grofste tot fynste.

    • Francois Landsberg says:

      Die materiaal wat ons verskaf is n chrome sand. Hy is van die funste wat mens kan kry en werk puik op al ons sand blast guns.

  10. David Maguire says:

    Hi I’m considering to get the 90l sandblast pot connected with the the 150l petrol belt drive compressor, 8bar, 6.5HP.

    How do you think this would work with a 3.6mm nozzle to clean the steel drop sides of a truck and steel frames etc( Large lenghts such as 2-3m 50mm wide) etc

    Practical or would a larger compressor and nozzle be needed?

    • Francois Landsberg says:

      You will get the work done just fine. That’s a good size of the nozzle. That compressor has very good CFM delivery. But you will have to experiment with the abrasive depending on the material you are blasting. It’s hard to recommend a nozzle size since you can use a large variety of sand.

  11. Leslie says:

    Hi Francois. I am a pensioner and would like to colour code my SUV silver sprayed alloys to black. Can I sandbadblast the rims.? I only have a portartable gravityfeed sandblaster and a 50litre compressor .I have plenty of time to do it ,thats for a proper job. Do you suggest a 100litre tank ?
    What grit size do U recommend

    • Francois Landsberg says:

      Any compressor will work if it can give 6 bar problem is if the machine is too small the process will take much longer. A 100l is OK but bear in mind anything below 200l 2.2kw will fall behind and you will have to stop work in between. Also, the machine might overheat, so maybe do small sections at a time.

  12. Rob says:

    Good day, looking at the MAC-AFRIC Sand Blast Gun Gravity Feed / Top Load AGUNSB-118 to remove pain from 2 Fixed Jack Stands, will this work and where do one buy the sand. Have been to a store but they could not answer me properly.

    • Francois Landsberg says:

      It will work. We sell 30kg of a chrome sandblast sand but you can use any sand that is dry and consistent. The chrome type we carry is just very commonly used in many industries and works well for most aplications.

    • Francois Landsberg says:

      Hi here is the composition

      Calcium Oxide 2% Titanium Dioxide 1%
      Magnesium Oxide 20% Iron Oxide 8%
      Aluminum Oxide 26% Chrome 3 oxide 12%
      Silicon Dioxide 32%

  13. Heino says:

    Good day.

    I have quite a large sand blast cabinet that is build at home.I want to use this for sandblasting stationary engine parts that I restore.This parts is normally very old and rusted.The size of the parts is no bigger than 500mm x 500mm.
    I do not want to have a hard time sandblasting these parts so I think a 220v compressor wont be a good choice for me.I am looking at a petrol compressor from you.What will you reccomend.A 6.5hp or 15Hp petrol driven air compressor.

    • Sewes le Roux says:

      Good day Heino.
      Thank you for your valued enquiry.
      Yes you are correct, our biggest 220-230 Volt single phase compressor will be able to sandblast, but only for short periods of time due to the CFM output rating….this can be frustrating.
      We always recommend a larger compressor with higher CFM rating for sandblasting applications so therefore the 15Hp petrol driven model would be our recommendation, offering 614l/min @ 90PSI (6Bar)
      As a rule of thumb, the pressure for abrasive blasting should never exceed 7 bar. Exceeding a 7 bar pressure will tire the blaster out faster, resulting in unnecessary operator’s fatigue.
      This further re-enforces the need to focus on the CFM the compressor can produce rather than the pressure.

      From this you can see that the larger the nozzle size, the more CFM is required. This then leads to another question! What size nozzle will you require?
      Nozzle selection depends on the size of the blast pattern you are looking for. If you are blasting large sheets of metal and require a larger blast pattern, a 9.5 -12.5mm nozzle will suit your application. If you are, however, blasting steel structures and require a smaller blast pattern we would then recommend a 6 .5– 8mm nozzle.
      There are so many factors to take into consideration when it comes to abrasive blasting, but by having the right foundation with the correctly sized compressor, you are already one step ahead of the game and improving your production.

      • Heino says:

        Thank you so much.
        I will by blasting engine parts only as a hobby and parts is quite small.So I do not mind to spend some time with a small nozzel.
        As long as I do not have to blast for 30 sec and have to wait for the compressor.

    will a 200L 8cfm compressor be sufficient enough to strip a car …need to remove the 2k paint from the body ? ..what gun do you have in stock that would work for my application?
