Frequently Asked Questions

How much media does it use?

Approximately 1 kg of media for every blasting hour. However, this can vary depending upon many factors i.e. angle of slurry impact on the work-piece, air atomisation pressure, media durability, etc…

Do you supply parts / media?

We supply everything you need to keep your machine operating. Dana-Ridge has been supplying equipment for our machines since 1987.

What is the difference between these machines and the hobby machines?

The commercial machines are designed to provide a strong supply of slurry to the gun and a larger volume of air. They also agitate the media/ water more efficiently. The pumps can range anywhere from 1.5kW up to 11.5kW . This all adds up to a more powerful machine that will process parts more efficiently and have a greater range than those with small submersible pumps and smaller air jets. Parts are more robust and some have features to minimise operator error (useful when you have a variety of workers using the machine – some with a lower “care factor” than yourself)

How long does the pump last?

The pumps are extremely reliable and hard-wearing. Based on historical averages, approximately 12,500 to 14,000 operating hours from the urethane lined pump is achieved. **NOTE**Those figures assume the use of a larger aggressive aluminium oxide. Using gentler blast media, such as glass bead abrasive, achieves even longer life.  Glass bead is significantly softer and gentler. They are commercial machines designed to work long hours and we also keep a range of parts on hand. 

Why fibreglass and not stainless steel cabinets?

Fibreglass is quieter, easily repaired and is ideal for wet conditions. The internal fibreglass walls are protected from the blast stream by internal white PVC curtains which also increase visibility by intensifying the overhead cabinet light. If you prefer stainless steel then our Saturn range of machines will fit the bill.

What type of media can I use?

You can use most abrasive media except for steel based abrasive such as steel shot & slag. Steel will severely damage the polymer lining of the pump.

What are the most commonly used media

  • Glass bead
  • Sodium Bicarbonate (Soda)
  • Crushed glass
  • Garnet
  • plastic
  • apricot kernel
  • silicone carbide
  • walnut shell
  • Aluminium oxide

What are the advantages over a dry-blaster?

  • Far superior quality of finish
  • Able to blast a wider range of surfaces without damaging the part
  • Wider range of finishes available
  • No dust
  • No heat distortion
  • No fingerprint marking when touching blasted parts
  • No media impregnation into the metal
  • Longer media life = reduced abrasive costs
  • Able to use much finer media than a dry blast cabinet
  • No need to pre-clean or degrease parts

What do I need to get started?

Our machines come with a starter kit comprised of:

  • 2 x 25 kg bags of media
  • 1 x 20 L drum of “Aqua No-Rust”
  • 1 x Media concentration test jar

It’s a Plug N Play machine. Just connect the water supply to run the window wash, the air from a suitably sized compressor and connect in the power supply (plug supplied on the 240-Volt machines, 3-phase machines usually hardwired by customer). The machines are ready to go

A turntable and gun mounting post are included as standard with our wet blast cabinets.

What is “Aqua No-Rust”?

  • “No rust” is an optional temporary rust inhibitor for use on ferrous materials. It provides up to 2 weeks protection if the part is stored indoors in a dry area. It can be removed with water if desired or painted straight over.

Is there any waste?

Very worn media and extra water from the window wash/ rinse gun will dribble out the overflow for catchment in a container or recirculate via the optional settlement tank.

Is it a closed system?

  • The media and water slurry will continuously cycle in the machine. As stated above extra water introduced to the machine will dribble out the overflow. This can be discarded (contact your local government authority to confirm the regulations regarding treatment of industrial waste water in your local area). Alternatively, you can purchase the optional 240L settlement tank which will create a fully closed system in which you will not require mains water supply as all water will be recirculated.

I have oily parts to blast, will that cause a problem?

Mildly oily parts will not cause problems. If there is excessive oil there is the optional product called “Aqua Kleen” which is a low foam detergent that helps dissipate oil.

How noisy is it?

  • Mars machine pumping slurry with no air is approximately 74dB

    Mars machine pumping slurry and air approximately 79dB

Can I safely blast “case hardened” components?

Yes, blasting will not ruin the hardened characteristics of the steel.

How hard is it to change media?

There are three options. The most basic is to direct the gun flow (air off) into a bucket. The solids will sink to the bottom for reuse later. There is also an optional “portable wet cyclone” that attaches to the machine and spins the media out into a separate pot, all with a simple turn of a butterfly valve. Now available is a mini porta-wet-cyclone for use inside the machine itself.
