Inspired by another YouTuber who made a huge wooden aquarium, he made a huge blast cabinet measuring 106x76cm using plywood and 2×4 lumber.

It’s made of wood, but it’s completely waterproof and can be used as a blast cabinet with no problems.
Compared to iron cabinets, which require sheet metal welding, the hurdle is low. To be honest, I can make it with just the tools I have on hand.

However, if I were to make it as is, the size would be a little large.
Maybe I should shrink it to the commonly used cabinet size of 93×58?
Astro Product’s SB846 is this size. Hmm, I’m having a hard time deciding.

I want to make my own wet blaster, so I did some research to find out what parts I need.

It’s called a Vapor Blaster in the US, I guess.

Necessary discharge volume

According to Vapor Horning Technologies, Inc., a nozzle with a 10mm inner diameter needs to be able to cover 20CFM = 566L/Min to maintain 50-60psi.

For personal use in the garage, a 5 horsepower air compressor is recommended. It can be roughly calculated as about 3-4 CFM per horsepower.

 

Nozzle diameter and required size of air compressor

By reducing the nozzle diameter, a smaller air compressor can be used.

Nozzle diameter Nozzle cross-sectional area Ratio Discharge volume Size
10mm 25π㎟ 100% 20.0CFM / 566LM 5HP
8mm 16π㎟ 64% 12.8CFM / 362LM 3HP
6mm 9π㎟ 36% 7.2CFM / 204LM 2HP

Basic Setup

Minimum required parts

  • Blaster gun
  • Air cock
  • Air compressor 2HP or more
  • Water pump 1.5HP or more
  • Bottom bucket
  • Media (abrasives, alumina, glass beads, etc.)
  • Pressure-resistant hose

For the time being, I’ll use a clothing case or something for the blaster cabinet.
The water pump is about 1.5 horsepower, 1100w.

Bonus

The output of the air compressor required for air tools is

  • Nailer 2CFM
  • Impact wrench 3/8 3CFM
  • Impact wrench 1/2 4cFM

The output of the air compressor required for painting is

  • 12CFM 70PSI

I want an air compressor with about 3HP.
Oil-free is suitable for painting, but it has a small number of bulbs and is quite expensive.

I’ll try 2HP for now
