Displacement Products

Airpot Corp’s displacement products include Self-Aligning Pneumatic Actuators and basic Piston / Cylinder Sets that are constructed using a graphite piston / borosilicate glass cylinder combination in which each piston is selectively matched to fit the cylinder with extremely close clearances. They have unparalleled low friction, responding to forces as low as only a few grams and pressures less than 0.2 psi. Starting and running friction are almost identical, preventing jerky, uncontrolled starts and providing uniform smoothness throughout the full stroke of the device.

Airpot Actuators operate as low friction air cylinders, but also have uses as pumps and pressure sensors.  The most compact of the Airpot actuator line, they have self-aligning capability and offer very low mass for super responsive motion. They make possible accurate force sensitivity and actuation with uniform motion, allowing amazingly smooth movement and pressure sensing operation even over distances less than 0.1 inch and cycle rates ranging from very slow to very high speeds- up to 10cps or more. They can be used to dispense small volumes of air, sense a flow, generate airflow or air pressure, or accurately provide a visible volume indication with ease. Airpot self-aligning pneumatic actuators are ideal for pumping small volumes of air or generating low pressures with minimal energy use. These lightweight compact actuators are also great for devices requiring portability.

When designing with our accurate force pneumatic displacement products, here are the main functional differences to consider:


  • Self Aligning and ready to mount
  • Compact
  • Single acting (can be pressurized in extension direction only but can be returned with vacuum)
  • Can be used to generate vacuum or pressure for pumping applications

Piston and Cylinder Sets:

  • Basic building blocks ready for your own mounting design
  • Linear and rotary motion capability-even simultaneously
  • Varied configuration and design choices
  • Most easily customized
  • Lowest cost components
  • Totally non-metallic
  • Low mass
  • Transparent cylinder provides visible piston position
