Air rivet tools and the power behind their success


Selecting an air compressor to suit your rivet gun.  

Some of the most popular tools on the market are air powered rivet tools and widely recognised as the go-to choice for high production workshops. Air riveting guns are the compact lightweight option compared to many cordless battery tools and often deliver more torque (in layman's terms, more strength). Air riveting tools or pneumatic riveters are ideal for dynamic workshops where continuous use is required, as they don't overheat like cordless tools can. However, these advantages mean very little if you don’t have the right set-up and capacity of a well-maintained air compressor.

Operating hassle-free air tools starts with having a good air compressor that matches your daily production needs. Air compressors work by forcing air into a container and pressurising it. Think of it like an open balloon: where the compressed air is used as energy upon it’s release. The size and configuration of your setup are crucial, along with key add-on features like an air filter and pressure gauge to ensure smooth, reliable riveting. You may need more than one gauge as the pressure may differ between the compressor and the tool - we have seen this on numerous occasions. And don’t overlook the importance of an air filter. Air rivet guns perform best when powered by clean, dry air free from moisture and contaminants.

Purchasing an air compressor for air rivet gun.

Choosing the right air compressor will require reviewing the your application. Evaluate the rivet tools you'll be using and their CFM and PSI requirements, then select a compressor that exceeds those needs by adding a small buffer for potential leaks or additional tools.   

🔧Air Compressor Essential Features

  1. Tank Size.
    • Measured in litres (e.g. 20L, 50L, 100L).
    • Large tanks (200L) Ideal for multiple tools with a steady airflow.
    • Medium tanks (≥100L - 200L) For tools that need continuous air. 
    • Smaller tanks are suitable for light use and more portable. 
  2. Air Flow Rate (Measured in CFM - Cubic Feet per Minute)
    • Means how much air the compressor can deliver - higher rate is better for heavy-duty riveting. 
    • Match the CFM rating to your tool. A general-purpose compressor has 5–10 CFM at 90 PSI.
  3. Operating Pressure (Measured in PSI - Pounds per Square Inch)
    • Pressure output; most tools need around 90 PSI.
    • A good unit should offer at least 100–125 PSI.
  4. Engine Power
    • Powered by electricity, petrol, or diesel.
    • Energy measured in HP (horse power) or kW (kilo watt).
    • Electric means quiet, clean, and suitable for indoor use.
    • Petrol/Diesel are portable & powerful - ideal for outdoors. 
    • More power = better for heavy-duty or continuous work.
    • 1.5–3 HP (or ~1.1–2.2 kW) is ideal for general workshop use.

🛠️ Convenience & Build Features

  1. Oil-Free vs Oil-Lubricated
    • Oil-Free: Less maintenance, lighter, suitable for light/clean work.
    • Oil-Lubricated: More durable, better for industrial use.
  2. Duty Cycle
    • Indicates how long it can run before resting (e.g. 50% = run half the time).
    • Look for a high-duty cycle (≥50%) for serious work.
  3. Portability
    • Consider wheels, handles, and weight.
    • Vertical tanks save floor space.
  4. Noise Level
    • Measured in dB(A). Below 70 dB is considered quiet.
    • Silent or low-noise models are available for indoor use.

🧰 Safety & Usability Features

Safety should never be overlooked when buying an air compressor.

  1. Thermal Overload Protection
    • Prevents motor from overheating.
  2. Automatic Shutoff Function
    • Stops motor when tank reaches max pressure.
  3. Air Filter and Drain Valve
    • Easy-access drain valve helps prevent moisture buildup in the tank.
    • Clean filters ensure long-term performance.
  4. Dual Output Ports
    • Let’s you run two tools at once.

🔄 Key Features To Seek

  • Regulator with Clear Gauge
  • Quick-Connect Couplers
  • Rubber Feet (to reduce vibration)   

Maintaining an Air Compressor For Hassel-free rivet guns. 

A well maintained air compressor ensures it runs efficiently and has a long lifespan. Different compressors come with different maintenance needs, some require regular oil changes, filter cleaning, and checks for wear and tear. If you prefer minimal maintenance, consider an oil-free compressor. However, for heavy-duty industrial use, oil-lubricated models last longer and perform better. Here are beginner-friendly air compressor maintenance tips:

🧰 Daily Maintenance

  1. Check Oil Level (for oil-lubricated models):
    • Top up if low; use manufacturer-recommended oil.
  2. Drain Moisture from the Tank:
    • Release the water from the tank using the drain valve to prevent rust and corrosion.
  3. Inspect for Leaks or Unusual Noises:
    • Hissing sounds may indicate air leaks; tighten fittings or replace damaged hoses.

🔄 Weekly Maintenance

  1. Clean the Air Filter:
    • A dirty air filter can reduce efficiency and contaminate air tools. Wash or replace as needed.
  2. Check for Vibrations or Loose Bolts:
    • Tighten any loose bolts or nuts.

🗓️ Monthly Maintenance

  1. Inspect Safety Valve:
    • Pull the ring to ensure it opens and closes properly.
  2. Clean Compressor Exterior:
    • Wipe down to remove dust and debris that can cause overheating.

🧪 Quarterly or Every 3 Months

  1. Change Oil (for oil-lubricated models):
    • Refer to the manual for frequency and procedure.
  2. Inspect and Clean Intake Vents:
    • Ensure the compressor has proper airflow.

📅 Annual Maintenance

  1. Check Hoses and Replace If Needed:
    • Look for cracks, brittleness, or wear.
  2. Inspect the Tank for Rust or Damage:
    • Inside and out—consider professional inspection if unsure.

✅ General Tips

  • Follow the User Manual: Always prioritise manufacturer guidelines.
  • Use in a Clean, Dry Area: Helps reduce dirt intake and moisture buildup.
  • Don't Exceed Pressure Limits: Prevents wear and improves safety.

Purchasing an air compressor to suit your rivet guns is not as simple as picking the first one you see online or at your local tool store. It's important to make a selection based on your requirements whilst considering performance, efficiency, and value. Choosing the wrong air compressor type or size can lead to poor performance, wasted energy, or costly repairs. The right air compressor should meet your needs, fit your budget, and work efficiently for your specific riveting application.
