Design meets experience – The new S

Leister New TRIAC ST
Der neue TRIAC ST
The new hot-air hand tool (heat gun) TRIAC ST from Leister is primarily used for welding and processing plastics. Extra technical features were consciously foregone during its development. Its outstanding features, like its predecessor the TRIAC S, are its ease of use, reliability and versatility. A prominent feature here is the two-component handle, which is not only attractive visually but also gives the user perfect grip. The low weight of less than 1 kg (2.2 lb) ensures a perfect weight balance. The innovative motor and turbine design, combined with the heating element familiar from the TRIAC AT, give it even better value. The two air filters, which can be easily removed and cleaned, are also new. More than 80 nozzles, which are also compatible with the TRIAC AT and TRIAC S, fit the new TRIAC ST. That makes all conceivable applications possible, for interior as well as exterior use.

Leister New MISTRAL System
Two different model groups are available – the MISTRAL 2, 4, and 6 PREMIUM, and the top-of-the-line MISTRAL6 SYSTEM. The MISTRAL6 units have a brushless, maintenance-free motor. This makes it outstandingly well suited for continuous operation in industrial settings. In the MISTRAL PREMIUM line, the blowers and heating can be switched on and off separately. The top model in the MISTRAL6 SYSTEM can either be operated using its integrated controls or via an external system interface. The display shows all relevant user status information and is used for programming all the versatile application possibilities. An integrated temperature alarm delivers the exact temperature information for the internal closed loop operation for this type. The MISTRAL6 SYSTEM also has an automatic cooldown function. The volume of air and the temperature can be perfectly set for every application using the innovative eDrive operator control module. The integrated heating element protection with photo transistor and the temperature protection switch for the unit protection provides additional safety. All units have an integrated connection adapter with an internal 1-inch thread. All models are equipped with mounting tabs accessi-ble from above.
