So that work in dental laboratories can continue undisturbed even when furnaces and polishing equipment are in use, Mihm-Vogt offers matching extraction units. These units exhaust extracted air outside the building and have steplessly variable suction to ensure good air quality at workplaces at all times. A range of sizes is available to suit the number of laboratory furnaces or polishing units on the premises. Extras including a programmable 99-hour timer and a grease filter help to ensure comfortable, pleasant working conditions. Only reusable grease filters are used; they can be easily removed for cleaning and refitting.
