2UUL BB Nano DA90 30W Precision Mini Fan

2UUL BB Nano DA90 30W Precision Mini Fan. SKU GN-10195. Model code: DA90. The BB Nano DA90 30W precision mini fan is a compact tool for micro-electronics and mobile repair workshops. It delivers a strong, concentrated airflow suitable for rapid cooling of integrated circuits after soldering and for forced-air cleaning of optical surfaces or housings before reassembly. The high-performance motor produces a precise airflow, while the integrated nozzle helps direct air exactly where needed without easily displacing nearby small components. Unlike traditional compressed air solutions, it is rechargeable via USB-C and does not spray moisture onto sensitive components. Its aluminium and high-density polymer construction, ultra-portable format, and quick-trigger one-handed control make it suitable for use under a microscope or in tight smartphone work areas. Key specifications: Power: 30W Model: DA90 / BB Nano Power supply: built-in lithium battery, USB-C rechargeable Materials: aluminium body and high-density polymer Control: quick-trigger button for one-handed use Format: mini, ultra-portable Key benefits: Quickly removes dust, glass debris, and solder residue without physical contact Helps reduce waiting time between soldering steps by cooling the PCB Can replace disposable compressed air cans as a long-term workshop solution Compact cordless design for easy mobility between workstations Workshop tip: use it before applying a touchscreen or tempered glass to remove the last dust particles. For post-solder cooling, use gentle sweeping motions over the freshly soldered chip to avoid excessive thermal shock.
