Cartridge retainers are used to pressurize cartridges for production use.
Two main versions are available in various sizes to accommodate all types of cartridges: the traditional version, where the air pressure pushes directly on the plastic piston of the cartridge, and the mechanical version, where the air pushes a mechanical piston that applies the thrust on the plastic piston of the cartridge.
All versions can be equipped with pressure regulators and level sensors to monitor the production process.
