Air Outlet Temperature Compressed Air Cooling Vest - Function and performance: Uses a vortex tube to provide cooling. Outlet temperature is adjustable with a manual knob; a thermometer lets you monitor. In normal operation, outlet temperature is maintained within ±1 degree Fahrenheit (±0.6 degrees Celsius) continuously. - Materials and safety: Made from Nylon and Oxford fabric, sleeveless design. No spark flicker hazard. No electric or chemical refrigerants; only filtered compressed air for industrial use. No cleaning required. - Operation and maintenance: Easy to control; cooling produces no waste; components do not require cleaning. - Comfort and suitability: Sleeveless design suitable for warm climates or summer use; lightweight and practical for long wear. - Compatibility and use: Requires a compressed air supply; no electricity needed beyond air supply. - Use scenarios: 1) Metallurgy, forging and welding environments with high heat. 2) Glass production, painting, sandblasting in hot or humid settings. 3) Boiler rooms or power plants where high temperature and humidity are present. - Key benefits: Precise, maintenance-free cooling without electricity or chemicals; no waste and no spark hazards; straightforward control and reliable performance in demanding industrial conditions.
