Product Description

The Upstroke (Priming for the Next Dose)

  • You release the actuator.

  • The compressed spring pushes the piston back up to its original position.

  • This upward movement creates a vacuum (negative pressure) inside the chamber.

  • The inlet valve opens due to this vacuum.

  • The vacuum simultaneously draws two things into the chamber:

    • Liquid from the bottle (via the dip tube).

    • Air from the outside atmosphere (via a dedicated air inlet channel, often built into the housing or piston).

  • The chamber is now refilled with a precise ratio of liquid and air, ready for the next press.

This cycle repeats with every pump, ensuring a consistent dose of foam each time.
