Dashpot damping is one of the simplest ways of eliminating vibration. The Airpot dashpot excels in providing a high ratio of damping-to-friction force.
In tape and film processors (as shown at right), a two-way damping Airpot significantly reduces idler arm vibration caused by stiction or take-up drive pulsation. The idler can still move freely to accommodate changes in the loop profile. Using an Airpot also improves the response during start-up acceleration.
In high speed fiber optic filament, wire, and textile winders, an Airpot is ideal where oscillation of tension idlers can cause broken filaments.
