Spec: Item Type: Cold Air Cooling Gun Material: Aluminum alloy Air Pressure: 6.9Bar Air Intake: 280L/min (10cfm) Maximum Cooling Capacity: 650BTU(164Kcal/Hr) Type: Standard Air Inlet: Female thread G1/4in Cold Air End: Female thread G3/8in How to Use: 1. The temperature difference of the swirl tube test is the limit temperature difference inside the cold air outlet under standard conditions and cannot be used as the operating temperature. The specific operating temperature can be adjusted through the internal adjustment valve at the hot end. Adjustment method: screw down the hot end silencer and rotate the built in adjustment valve to increase the temperature clockwise and decrease it counterclockwise. 2. The factory temperature setting is ‑25℃ for air pressure 0.69MPa, lower temperatures can be adjusted by yourself. Note: A temperature difference of ‑25℃ for cold air does not mean that the cold air temperature is ‑25℃ below 0, it means the temperature drop, For
