Airpot Precision Dashpots

When there is the necessity of reduceing or eliminating the harmful or excessive motion, Airpot dashpots offer highly accurate motion control, including vibration damping, spring damping, solenoid damping, and control of free fall velocity. Airpot’s precision glass cylinder and graphite piston technology produces instrument quality pneumatic devices uniquely designed and optimized for accurate, repeatable force control. As a result, a family of damping devices that operate with superior accuracy and little or no friction. Airpot “Accurate Force ” precision dashpots use ambient air to precisely and accurately control force, velocity and impact and are ideal for designing or improving a product line or building specialized equipment to do research, high level testing or precision assembly. Airpot Air Dashpots are available in 6 bore diameters ranging from .22 inches to 1.75 inches with either push, pull, or two-way damping and strokes from 0.5 inches to 3 inches.

  • Airpot precision dashpots are highly versatile and are used in a variety of applications where accurate motion control is essential. Here are some key applications:
    1. Vibration Damping: They help reduce or eliminate harmful vibrations in sensitive equipment, ensuring smooth operation.
    2. Spring Damping: Used to control the motion of springs, preventing excessive or erratic movements.
    3. Solenoid Damping: Ideal for controlling the motion of solenoids, ensuring precise and repeatable performance.
    4. Free Fall Velocity Control: They regulate the speed of free-falling objects, providing controlled and safe motion.
    5. Impact and Force Control: Airpot dashpots use ambient air to precisely control force, velocity, and impact, making them suitable for high-level testing, precision assembly, and research applications.

12 ways an Airpot differs from other damping devices

  • It has unparalleled low friction, responds to forces as low as only a few grams, and it’s smooth.
  • Starting and running friction are almost identical, which prevents jerky, uncontrolled starts.
  • It has a life-span of multi-millions of cycles. It outlasts most any machine in which it is used.
  • No seals are required, and there are no liquids to leak.
  • There is no limit to its cycle rate. It does not heat up or change viscosity under conditions of rapid and/or continuous cycling.
  • It’s made of self-lubricating materials.
  • It’s precise and accurate, easily adjustable over a 10,000 to one range, and it allows fine adjustments at installation.
  • It’s unaffected by extreme temperature variations and high G-loads.
  • The piston and cylinder will not rust, corrode, or deteriorate over time – even with little or no use over extended intervals.
  • It damps bi-directionally and uni-directionally.
  • It’s lightweight.
  • It’s easily customized to suit space availability and the majority of special performance requirements.

It sounds much simpler than it is.

  • The Airpot Dashpot is a motion damping device that reduces velocity, vibration, and oscillation in dynamic mechanisms.
  • This is accomplished by using a piston to force ambient air through an orifice at a controlled rate to dissipate kinetic energy.

The benefits are worth noting:

  • It prevents damage and violent or inaccurate response caused by shock and vibration in sensitive equipment and components.
  • It reduces impact noise and wear.
  • It provides simple, low cost, adjustable speed control without external power.
  • It provides non-electrical timing capability.

What type of applications benefit most from these special capabilities?

Any kind where these conditions are present:

  • Where smooth, near friction-free motion is critical.
  • Where responsiveness to low forces/low kinetic energy levels is required.
  • Where equipment is sensitive and precise.
  • Where clean operation is important.
  • Where cycle rates are high or life span needs to be long.
  • Where reliability is critical.
  • Where temperatures are extreme or environments are humid. Where high quality is a product feature.
  • Where non-electrical motion control is advantageous.
