Precision Dust Removal: The narrow nozzle directs a focused air stream toward watch movements, dials, phone parts and other small components without requiring direct surface contact. Push-Button Air Control: Press the built-in button only when airflow is needed, giving watchmakers and repair technicians better control during delicate bench work. Adjustable for Delicate Parts: The included flow valve helps reduce or increase airflow for different cleaning tasks, from watch cases to smaller precision components. Flexible Hose Routing: Choose a straight inlet or 90° elbow inlet to better match your bench layout and keep the air tube from interfering with hand movement. Ready for Your Air System: Includes tubing and connection fittings for easier setup with a clean, dry, regulated compressed-air source; air pump or compressor is not included.
