Industrial Hot Air Devices

Leister hot air tools are used in countless industrial production processes. In fact, there are very few industries that do not benefit from our versatile offerings, regardless if the process only operates with hot air or if it becomes more efficient with hot air. Leister has the right blower for every production line.

Reliable And Safe

The LHS 21L PREMIUM air heater features an integrated, active device and heating element cover. An additional implemented alarm contact ensures high process safety warns of excess temperatures and the resulting failures. The heating power can be continuously adjusted via a rotary potentiometer. The air heater is perfectly suited for continuous operation and delivers continuously high output in industrial production processes with its associated external blower.

The LHS 21L PREMIUM is designed for special assembly in machine systems. Thanks to its quick and easy to change heating element, maintenance downtimes are kept to a minimum, thereby keeping profits up. The innovative hot air technology also provides outstanding results for very specific industrial applications: Continuously heating furnaces and containers, activating and dissolving solvent-free adhesives and hot melt adhesives, as well as removing plastic flash and polishing plastic surfaces.
