Vacuum-powered dispensing: A piston or collapsible bag rises as product is used, preventing air from entering.
No dip tube: Unlike standard pumps, airless systems don’t require a tube, eliminating leftover product.
Outer shell: Typically made of plastic (PP, PET) or glass for durability.
Pump head: Press-down actuator for controlled release.
Internal piston/bag: Creates an airtight seal and pushes product upward.
Base plate: Maintains vacuum pressure and stability.
