FNIRSI intelligent hot air gun SMD 550W PID LCD 100-450°C SAG-55

The FNIRSI SAG-55 is an intelligent hot air rework station designed for precision electronics work, SMD soldering and detailed repair jobs. Its 550 W heating power and temperature range of 100 to 450 °C cover everything from fine surface-mount components to larger parts.

A PID control system continuously monitors and corrects the temperature in real time, keeping output stable without spikes or overheating. This helps protect sensitive components and gives more consistent soldering results. The heater reaches its set temperature quickly, and a dedicated cool-air mode lets you cool components down after soldering.

The brushless fan offers 20 adjustable airflow levels, up to 80 l/min, with noise below 65 dB, allowing precise control over delicate and larger parts. A colour LCD display shows temperature, airflow and mode at a glance, and three memory presets let you return to frequently used settings with one press.
