During a product demonstration, Leister showed the advantages of the PENWELD A and PENWELD S hot-air welders at Air Clean, an internationally active company that has been developing and producing comprehensive air treatment systems for more than 30 years.

Tightness as the key to success

Air Clean offers both biological and conventional air treatment solutions for a wide range of applications in the urban and industrial sectors. These solutions are based on an air supply system that usually consists of a fan and a duct network. The air to be purified is collected in these ducts and released after purification. For these ducts, as for the rest of the system, a completely tight seal is essential to ensure that no air escapes before cleaning is complete.

The systems manufactured in the Air Clean workshop (scrubbers, biotrickling systems, bioscrubbers) are either made of metal or plastic, depending on system type and application. Air Clean has relied on hot air solutions for many years to ensure flawless, leak-proof welding of plastic parts. Leister’s products are particularly valued for their reliability and ease of use.

Reliable partner for precise welding seams

The Leister PENWELD A convinced the Air Clean technicians straight away. In particular, they praised the compact design, user-friendly operation, integrated lighting and innovative features like the flexible connection on the handle, which is connected to the hot air hose. The “A” stands for Advanced and differs from the “S” (Standard) in terms of the display and integrated lighting.

In practice, the PENWELD has proven to be the ideal solution for processing polypropylene (PP) parts. Aside from applications for hydraulic lines, the hot-air welders are particularly useful for welding chemical scrubbers, tanks, containers, and pipelines.

Compact, strong and flexible in use

Compared to other welding solutions that Air Clean uses for these applications, the handy hot air welder from Leister impresses with its lighter weight and ergonomic grip. These properties allow you to work comfortably, even in hard-to-reach places that would be difficult to reach with larger devices. The ring-shaped work light, integrated directly into the handle, makes it easier to work in dark or shaded areas. The PENWELD Also offers remarkable performance for a device of this size and guarantees reliable and durable welding seams.

With the successful introduction of the PENWELD A at Air Clean, Leister has once again confirmed the quality of its plastic welding solutions. This cooperation further strengthens the long-term partnership between Leister and Air Clean – and creates a solid basis for future success.
