Fnirsi SAG-55 PLUS smart heat gun

FNIRSI SAG-55 PLUS 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 (<65 dB).


Intelligent safety and real-time monitoring
Built-in sensors constantly monitor the condition of the device. In the event of a malfunction, the system automatically cuts off the heating, protecting both the user and the equipment. This solution provides peace of mind, confidence, and safe operation even during long sessions.


Magnetic stand and automatic sleep mode
Thanks to a magnetic position sensor, the heat gun automatically goes into sleep mode when placed in the stand. The device activates cooling, accelerating heat dissipation and protecting the heating core from wear and tear – without the need to switch it off manually.


Three presets – one click for perfect settings
The FNIRSI SAG-55 allows you to save 3 custom temperature and airflow profiles, allowing you to switch between different tasks in an instant. One press is all it takes to return to your favorite settings and work faster, more comfortably, and without unnecessary adjustments.


Clear, color HD display
The large 1.54-inch LCD screen (240×240 px) displays all key information in a clear, colorful format. Temperature, airflow level, operating modes, and presets are always clearly visible, which significantly facilitates control and increases ease of use.


Well-thought-out design and compatibility with 850 nozzles
An ergonomic handle, heat-resistant metal + silicone housing, quick nozzle replacement, and an 80 mm long, 21.6 mm diameter heater (compatible with 850 series nozzles) make this heat gun versatile, durable, and ready for any service challenge.


Professional equipment in your workshop
AC 220V / 50 Hz power supply, minimal power consumption in standby mode (<0.7 W), 1.2 m long cables, compact dimensions and weight make the FNIRSI SAG-55 the ideal tool for both the workshop and mobile work. It is a smart heat gun that really increases the efficiency and comfort of everyday tasks.
