How does it work?

"An Airless dispenser is a non-pressurized, tamper-proof system, combining a mechanical pump with an airless filled and sealed container which delivers the product with no air intake. The container is either equipped with a piston or a pouch."

With an ordinary system, the product you pump inside the bottle is replaced by the same amount of exterior air. With an airless system, when you operate your pump, the amount of product dispensed outside is not replaced by air reentering the bottle when you release the pump.

The different types of Airless

Two versions of Airless designs are currently available on the market, with pistons or pouches depending on applications or products.

In the case of a system with a piston, product is supplied on the outside by a pump that sucks up the product causing the rise of a piston located inside the bottle, along with the product, and fills the gap left by the dispensed product.

For a system with a pouch, the pump draws the product contained in a soft pouch located inside a rigid container. The pouch collapses on itself, with no air intake, each time the pump is activated.
