TBH "Z" models are equipped with large particle filters for capturing excessive amounts of dust in applications with no vapors/gasses. TBH "ZA" models combine large particle filters with large activated carbon filters for maximum filtration and extraction. All LN 265 configurations are equipped with a powerful yet quiet blower motor capable of extracting up to 206 CFM (350 m3/hr) with low static pressure ensuring maximum airflow to remove particles. Ideal for soldering, laser processing, painting, and laboratory use, the GL 265 models can be utilized in a wide variety of applications.

GL DESK
The GL DESK model by TBH offers the most compact and efficient fume extraction and filtration system offered by TBH. The large flat top is sturdy and supports equipment as a base without the need of an additional work table saving space in the workshop. The steel construction easily supports equipment that fits on the large 27.5" square base, ideal for desktop laser systems along with other small-scale equipment. The powerful blower motor equipped on the GL DESK is capable of extracting up to 206 CFM (350 m3/hr) with low static pressure ensuring maximum airflow to remove particles. The quiet operation of the blower ensures that the filtration unit will not distract from the work at hand and is ideal for office or laboratory environments. Reducing environmental impact, the design of the GL DESK saves up to 65% energy compared to equivalent filtration and fume extraction technology. Filter replacement is simple with easy-access doors on the front of the system minimizing maintenance time.
