This compact cold air device is ideal for rapid cooling in small areas, such as machine tools, cutters, electronic components, and welding spots. It uses compressed air to generate low-temperature airflow for efficient cooling. Features: - Portable and easy to install with a flexible tube for targeted cooling. - Adjustable airflow and temperature via built-in control valve. - Durable construction for stable performance in industrial environments. Specifications: - Color: Silver and Blue - Material: Plastic and Metal - Condition: New - Cold Air Length: -13cm or 5.1in - Tube Length: -21.2cm or 8.3in Package Includes: 1 x Cold Air Device 1 x Flexible Tube Working Principle: Compressed air enters the vortex tube, creating a rotating airflow that separates into hot and cold streams. The cold air output is 25-45��C below ambient temperature, while hot air reaches up to 110��C. Note: Slight color variations may occur due to lighting or display settings. Measurements may have a tolerance of 1-3cm.
