FNIRSI SAG-55 Micro Hot Air Gun 550W with Stand – Smart BGA Rework Station with LCD Display

Imagine being able to desolder, repair, and mold delicate components with the same precision as a professional lab, but from your workbench. The FNIRSI SAG-55 is a compact, powerful, and easy-to-use hot air gun, designed for those who want clean and safe results: from motherboard and BGA repairs to DIY projects, heat shrink tubing, or repairing small electronic devices.

Its intelligent PID temperature control, low-noise brushless fan, and ergonomic handle with magnetic sensor make every repair a fluid, fast, and precise experience, even if you are not a professional.

⭐ Key features and benefits

• High-precision PID control (100°C – 450°C): The temperature remains stable, preventing thermal shock and protecting both electronic components and the internal heating element. Ideal for BGA, SMD rework, and delicate soldering.
• Brushless fan with 20 flow levels: up to 80 L/min with noise below 65 dB. You'll feel a firm and even airflow, without annoying vibrations or loud hums.
• 3 customizable quick presets: Save your favorite temperature and flow combinations to switch between tasks with a single touch (e.g., desoldering, heat shrinking, resin drying).
• Ergonomic handle with 1.54” LCD display: The grip is comfortable and lightweight; you clearly see temperature, airflow, and working status without taking your eyes off the soldering area.
• Magnetic sensor and smart sleep mode (Pro only): When the handle is placed in the Smart Sleep Stand, the gun reduces temperature, increases airflow for rapid cooling, and automatically enters standby. This ensures greater safety and extended lifespan.
• Configurable rapid cooling: Activate accelerated cooling mode to protect the heating element and store the tool sooner without waiting long minutes.
• Adjustable automatic shutdown: Choose between never, 5, 10, or 15 minutes to prevent forgotten power-ons and save energy.
• Designed for professionals and hobbyists: Perfect for mobile phone, console, laptop, and electronic board repair, SMD/BGA soldering and desoldering, heat shrink, DIY, and small workshop jobs.
• Clear and bilingual interface: Menu in English / Simplified Chinese, with adjustable screen brightness (levels 1–10) to adapt to any work environment.
• Compact and portable: Small handle and adapter size, 1.2 m cables to move freely on your desk without tangles.

🔧 What can you use it for?

• BGA and SMD rework: removing and soldering chips and small components without damaging the board.
• Repairing mobile phones, tablets, and consoles: loosening adhesives, repairing connectors, replacing components.
• Heat shrink and cables: shrinking sleeves and insulating connections cleanly and uniformly.
• DIY and hobbies: electronic DIY projects, modeling, resins, heat-sensitive adhesives.
• Quick drying: accelerating the curing of paints, inks, or resins on small surfaces.
