The core components of our cola machines (compressor, carbonation pump) are industrial-grade, high-quality parts with a service life of up to 8–10 years. The only regular consumable parts are small components such as seals, filter cartridges, and valve nozzles. The replacement cost for a set is only tens of RMB, and replacements are free during the warranty period. Under normal use and regular cleaning, these consumable parts can last 1–2 years, resulting in extremely low long-term maintenance costs.
