Why Having a Complete Blast Setup Matters

When planning a surface preparation project, it’s tempting to think renting or buying a blast pot is all you need. But blasting is more than just pushing abrasive through a nozzle. The right complete system prevents wasted media, minimizes costly downtime, and ensures your coatings adhere properly—saving you money and headaches long term.


What a Complete Blasting Setup Looks Like

  • Blast Pot: The heart of your system. It holds the abrasive and controls media flow. Whether you’re using a Schmidt pot or other pressure-hold system, it must match your job’s scope.
  • Air Compressor: Every blast setup needs the right CFM and PSI. Undersized compressors are a top cause of poor blasting. Always pair your pot with a compressor that exceeds your nozzle’s requirements. Explore our air compressors here.
  • Blast Hoses & Couplings: Properly sized, quality hoses reduce pressure loss and wear. Don’t overlook quick couplings, gaskets, and safety whip checks.
  • Deadman Control & Whip Checks: Remote shut-off prevents serious accidents. Whip checks keep disconnected hoses from whipping dangerously.
  • Moisture Control: Wet air clogs pots and ruins abrasive. A moisture separator or air dryer is essential—especially in humid climates.
  • Abrasive Media: Match to surface and coating removal needs. We stock garnet, steel grit, crushed glass, coal slag and more.
  • Safety Equipment (PPE): Every operator needs a NIOSH-approved respirator, blast helmet, gloves, suit, and CO monitor. Shop our full PPE line here.


Common Mistakes to Avoid

One of the biggest mistakes contractors make is only renting a blast pot—without considering the air, moisture, or safety requirements that go with it. Without the right compressor, moisture control, and PPE, jobs end up over budget, behind schedule, or unsafe. A complete system avoids these risks and keeps your project moving.

 

FAQs About Blasting Setups

Can I use my shop compressor for blasting?

Typically, no. Most shop compressors lack the continuous CFM needed for blasting. For example, a #6 nozzle at 100 PSI requires around 250-300 CFM—far beyond standard shop compressors. Always size your compressor to your nozzle.

What size compressor do I need for a #6 nozzle?

For a #6 nozzle at around 100 PSI, you'll want a compressor delivering at least 250 CFM to maintain effective blasting without pressure drop. If you’re running longer hoses or multiple tools, you may need even more.

Why does my blast pot keep clogging?
This usually points to moisture problems in your air line. Wet abrasive clumps together, blocking valves and hoses. Use a properly sized air dryer or moisture separator to keep your abrasive dry.

Do I really need a deadman control?
Yes—OSHA requires remote shutoff (deadman) controls for blasting operations. They instantly stop the blast stream if the operator loses grip or falls, preventing serious injury.

Can I run without an air dryer if it’s not humid?
Even in “dry” weather, compressors generate moisture from air compression. That means water still condenses in your lines. An air dryer or at least a moisture separator protects your pot and ensures steady media flow.

What kind of PPE do I need for abrasive blasting?
At a minimum: a NIOSH-approved supplied-air respirator or helmet, blast suit, gloves, steel-toe boots, and hearing protection. If blasting indoors or with hazardous coatings, you may also need additional ventilation or containment.

Can I just rent a pot without other equipment?
Technically yes—but it often leads to job delays. Many contractors underestimate the CFM they’ll need, forget moisture control, or skip critical safety gear. That’s why we build complete packages to avoid surprises on site.
