The SAG-55 Smart Hot Air Gun, developed by Shenzhen FNIRSI Technology Co., Ltd., is a compact, intelligent heat gun designed for a wide range of applications. It features microcontroller-based PID temperature control for fast heating with minimal thermal shock, protecting the heating element’s lifespan. A brushless fan with 20 adjustable speed levels ensures low noise and long service life, adaptable to various work environments.
The ergonomic handle integrates a magnetic sensor—automatically heating when picked up and entering standby mode when set down—for effortless operation. A built-in controller and display on the handle allow one-handed adjustment of temperature and airflow, along with three customizable presets for quick switching.
The rapid cooling function helps extend the heater’s life, while real-time monitoring sensors automatically shut off the heat in abnormal conditions for added safety. An LCD screen and LED indicator clearly show working status and temperature changes. With its comfortable grip and portable design, the SAG-55 is an ideal choice for both professionals and DIY users.
Key Features:
Quick Presets: Supports three quick temperature and airflow presets for easy switching. Adjustable airflow levels from 1 to 20 and temperature range from 100°C to 450°C.
Magnetic Sensor Cooling: Automatically cools down and enters standby mode when the handle is placed back on the holder. (Only Pro set)
Auto Standby After Cooling: Enters standby mode once the temperature drops to the set value (adjustable between 70°C and 100°C).
Rapid Cooling: When enabled, increases airflow during standby to accelerate cooling. Can be turned on or off as needed.
PID Precision Temperature Control: Utilizes microcontroller-based PID control for fast, stable heating with minimal thermal shock, extending the lifespan of the heating element.
