What are the structural advantages of the Series 2.1 in terms of long-term durability?
Unlike many standard models, the Series 2.1 is engineered to eliminate critical wear points: it features a non-removable airflow baffle that ensures atomisation stability without the need for adjustments, and a Gasketless Dual-Taper Nozzle that ensures a permanent leak-free fit, reducing both the risk of leaks and maintenance costs.
