Frequently Asked Questions

  • How Does A Piston Air Compressor Work?

    A piston air compressor works using a valve system and two stainless steel valve discs. The piston moves downward and draws air into the cylinder, then the largest disc flexes to fold downward, allowing the air to pass. As the piston moves upward, the large disc flexes again to seal against the valve seat. The compressed air is then forced through the hole in the valve seat and delivered to the end process.

  • What Size Air Compressor Do I Need?
    This will depend on what you want to power, and for how long. Air compressors with lower CFM ratings between 10-20 are ideal for less demanding tools like nail guns, air grinders and sanders. On the other hand, air compressors with CFM ratings of 50 or above are well-suited for more demanding tools like jackhammers, rock drills and impact wrenches. We also have a helpful guide on choosing the right size air compressor.
  • What Are Piston Compressors Used For?
    Piston compressors are commonly used throughout industrial, commercial and trade industries to provide workshop or instrument air to air tools, paint sprayers and abrasive blast equipment.
