Fnirsi Sag 55 550W Hot Air Rework Station PID LCD Display

Meet the FNIRSI SAG 55 550W Hot Air Rework Station—the compact, intelligent solution for precise soldering, desoldering, and rework tasks. With microcontroller-based PID temperature control, it heats quickly with minimal thermal shock, protecting the heating element and extending tool life. The brushless fan delivers smooth airflow (80 L/min) across 20 adjustable levels, enabling clean, reliable results across SMDs, BGA, and SM component tasks. Its ergonomic handle includes a magnetic sensor that automatically powers up when you lift it and enters standby when set down, letting you work with one hand while keeping the other focused on your project. Built-in display on the handle offers quick temperature and airflow adjustments and three presets for common jobs, making it ideal for both professionals and DIY enthusiasts. Designed for safety and longevity, the SAG-55 features real-time sensors that can shut off heat if abnormal conditions are detected. A rapid cooling function accelerates cooldowns to extend the heater's life, while standby modes and adjustable temperatures (100°C to 450°C / 212°F to 842°F) ensure you’re always at the right setting. The large 1.54-inch LCD (240x240) provides clear feedback, and the device operates quietly at under 65 dB for comfortable use in busy workshops.
