Jochen Zimmer slowly runs the burner over the gold nugget until it is completely liquid. Then the master goldsmith pours the mass into a crucible. He will need many more hours of work before the old gold is turned into a new, individually crafted piece of jewelry.
These hours are spent in his workshop by the man from Hassfurt, who has been creating unique pieces from high-quality materials for his jewelry studio for 20 years and with two female employees. Jochen Zimmer does not have to worry about the harmful vapors, fumes and dusts that are released, for example, when melting, soldering, grinding or polishing gold and other precious metals – at least not since he started using the Filtercase SL from Teka.
Flexible and space saving
The resulting pollutants are discharged via an extraction arm made of aluminum tubes. Jochen Zimmer can conveniently move this into any desired position via three joints, and bring the pipe nozzle close to the discharge point – as recommended by the trade association. The Filtercase SL, which collects and filters the polluted air, is hardly noticeable in the small workshop. It fits on a workshop cabinet due to its small size (280 W x 330 D x 440 H mm) and little weight (15 kg). Another is located under a work table.
The Filtercase SL is equipped with a multi-stage filter system. A pre-filter mat separates the coarse particles. The air is then passed through a fine dust filter, where even the last fine smoke and dust are separated. An activated carbon filter mat binds gases and unpleasant odors. The filter system is equipped with a powerful high-pressure turbine, which can be regulated continuously. After filtration, the cleaned air is returned to the workshop via a rear discharge grille. Automatic filter monitoring shows the user when a filter change is necessary. The changeover is carried out in a maintenance-friendly manner via the cover of the unit, which is secured with tension locks. The device is ready for immediate use.
Jochen Zimmer is satisfied with the devices: “I use them for about three hours a day. They work perfectly, are very space-saving and the volume is also okay.
