Based on our product design, the main difference lies in cooling and reliability. Our fanless models use passive heat dissipation with no internal fan, making them noiseless and dust-free. This design removes the risk of fan failure. In contrast, fan-equipped models can accumulate oil and dust in kitchen or retail environments, which may cause unusual noises and overheating. They also have moving parts that are more prone to malfunction, potentially within 1-2 years of heavy use. Fanless systems offer more stable, long-term performance, which is why we prioritize this design for durability in busy commercial settings.
