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.

How they work
All Airpot damping devices are dashpots generically, but for ease of discussion, we identify configurations in which the piston rod is attached to the load being damped as dashpots.
We identify configurations in which the piston rod is struck by — but not attached to the load — as shock absorbers or snubbers. Either term is acceptable.
The materials we use
Whether it’s a dashpot or a shock absorber, the materials we use are chosen for inherent lubricity, high strength-to-weight ratio, excellent stability under temperature and humidity extremes, close coefficients of thermal expansion, and non-deteriorating performance due to age or non-use.
The component parts:
• Graphitized carbon piston, precision ground to millionths of an inch TIR
• Annealed, borosilicate glass cylinder. Precision fire-polished bore.
