On the HL 1820 S, the temperature not only adjusts from 120 to 750 to 1,100 °F in three stages - the airflow does too ( 4, 7 and 13 cfm ). The optimized weight balance virtually rules out fatigue while working. The ergonomically shaped handle with soft inlay ensures optimum handling and the integrated thermal cut-out prevents over heating. The tool can be used with all industry standard nozzles, making all sorts of different applications even easier, for example, de-icing, drying, shaping, heat shrinking and much more.
