The units in the GL Desk-Series were specially designed as base units for compact lasers. They allow space-saving positioning of the laser and extraction and filter system and eliminate the need for an extra work bench. Together with the GL series, they were designed as particularly environmentally friendly extraction and filter systems, reflecting the requirements of TBH GmbH as an environmental technology company. We use special energy-saving and noise-reduced blowers that allow for use even in low-noise environments, such as laboratories and offices. Due to constantly increasing energy costs, device concepts such as the GL Desk-Series are becoming increasingly important.



  • Base unit for compact lasers
  • Extraction and filtration system as work bench

Functional Principle

A flexible hose is used to extract the contaminated air from one of the compact lasers positioned on the system and transport the contaminated air into the filter unit. In the filter unit, the contaminant particles are filtered into different filter levels according to their size. Filter units that are equipped with a molecular sieve (for example activated carbon/BAC Failters) remove the majority of gaseous contaminants. Afterwards the purified air can either be circulated back into the work area or diverted outdoors through an exhaust duct. Recirculating the air in the work area is an easy way to reduce energy costs.
