This Upgraded Digital 858D SMD Rework Station is Anti Electrostatic Hot Air Rework Station Closed loop control sensors with intelligent cooling system digital LED temperature display advantage: SMD tool 858d is used of imported air pump for low vibration, noise free design and maintain a quiet working environment. The air gun would automatically decrease the temperature when placed on the stand, the temperature would rise once picked up. Anti static design prevents leakage due to static electricity and damaged components. Input voltage 220vac ± 10 percent 50hz/110vac ± 10 percent 60hz output power 280w (max) air pump membrane type temperature range 100 degree Celsius 480 degree Celsius air output 23l/min (the max. ) Display digital LED display. The handle housing is made of flame retardant material with high flame resistance and built-in temperature protector which help to automatically cut off power when overheating occurs, when the fans stop running due to the damaged.
