The LHS 21S CLASSIC is a further development of Leister air heaters and offers even more power than the LHS 15 line with a 1000 to 2000 watt capacity. This air heater’s compact size is remarkable at only 67 mm (2.64 in), while still offering immense durability and reliability. Leister quality standards ensure that the LHS 21S CLASSIC is robust and requires very little maintenance. This is reinforced with its alarm system that will detect if the heating element and device is overheating.
Designed for special system integration, the LHS-21S can be used for various applications: Sterilizing, drying, welding, cleaning, shrinking, shaping, deburring and activating are all more efficient and reliable thanks to Leister’s proven hot air technology. With their simple design, Leister’s hot air components – including air heaters, hot air blowers, nozzles, etc. – are fit to perfection with demand-oriented integration for industrial machines and systems.
