The FNIRSI SAG-55 is a compact hot air gun designed for electronics rework, soldering and heat shrink applications.
Precise temperature control and adjustable airflow make it suitable for SMD and BGA component work.
Temperature Control
Adjustable temperature range from 100°C to 450°C.
PID control system maintains stable heat output.
Rapid heating gets you working quickly.
Controlled heating reduces thermal shock to components and extends element life.
Adjustable Airflow
Brushless fan with 20 speed levels.
Maximum airflow of 80L/min.
Quiet operation below 65dB.
Match the airflow to your task. Lower speeds for small components. Higher speeds for larger areas or faster cooling.
Built-in Display and Controls
The 1.54-inch LCD screen shows temperature and airflow settings clearly.
All controls are on the handle for one-handed adjustment.
Three programmable presets let you save your most-used settings.
Switch quickly between tasks without resetting each time.
Adjustable screen brightness for different lighting conditions.
Choose Celsius or Fahrenheit display.
Magnetic Stand with Auto Standby
The handle contains a magnetic sensor.
Lift the gun from the stand and heating activates.
Place it back and the gun enters standby mode automatically.
No fumbling for switches while holding the gun.
This also reduces energy use and extends element life between tasks.
Safety Features
Real-time monitoring shuts off heat if anything abnormal is detected.
Rapid cooling function increases airflow during standby to cool the element faster.
Protects both you and the tool during operation.
