How can I make my garage compressor quieter?

Making your garage compressor quieter is as simple as running it inside a soundproof but ventilated enclosure. You can also put a muffler on the intake to try a lower the motor noise. What more, you can try extending the air intake to the outside using a heavy-duty hose. It will help take all the operating noise outdoors. Another way is to install thick rubber on the air compressor motor; it acts as an excellent sound dampener and absorbent.

Can I leave the air in my compressor?

Of course not! You should empty any air remaining in the air tank daily after use. When air is compressed, condensation takes place, forming water inside the tank. The water needs to be drained as soon as possible to prevent corrosion and rusting. That’s why air compressor manufacturers put a relief valve at the bottom of the tank to release the air and the water in the tank.

Can you paint it with a 20-gallon air compressor?

Yes, you can, but not effectively. It might be too small for most painting jobs or result in an uneven flow of paint. The recommended air compressor for painting is at least 50 gallons. If you can afford a bigger one, then get it. An air compressor with a 60-gallon air tank or more can handle most painting tasks. What’s more, you can paint most surfaces even with a single pass.
