FNIRSI SAG-55 smart heat gun

FNIRSI SAG-55 Smart Heat Gun

The FNIRSI SAG-55 is a smart hot-air heat gun designed for precision electronic work, SMD servicing, and demanding home and professional users. With 550 W of power, a wide temperature range of 100–450°C, up to 20 airflow adjustment levels, an intelligent safety system, fast heating and cooling, a color LCD display, and smart automatic functions, this tool sets a new standard for comfort, control, and safety at work.

Precise temperature control thanks to PID technology

The advanced PID system constantly monitors and corrects the temperature in real time. This allows the heat gun to maintain stable operating parameters without spikes or overheating, which translates into greater soldering accuracy, less risk of component damage, and a longer heater life.

Fast heating and instant cooling

The FNIRSI SAG-55 instantly reaches the set temperature, saving you time from the very first second of operation. With a single button, you can activate the cold air mode, which allows you to quickly cool the components after soldering and safely put the device away without the risk of overheating.

20-step airflow adjustment – full control over the air stream

The efficient brushless fan offers 1–20 levels of linear airflow adjustment (up to 80 l/min). This allows you to perfectly adjust the airflow to delicate SMD components or larger components, ensuring precision, smoothness, and low noise (
