Description
Dürr Dental VS 900 S Suction Unit
The Dürr Dental VS 900 S is a wet (VS) suction unit for 3-5 treatment chairs, with 3 operators working simultaneously. “VS” stands for vacuum generation and separation: both functions are combined centrally on one drive shaft, which is cost-effective, saves space and removes the need for separation machines on the dental units. VS units can aspirate large quantities of liquid without interruption and can be installed in a basement, adjoining room or the treatment room itself.
Key Features:
-
Capacity: 3-5 treatment chairs, 3 simultaneous operators
-
Wet System: Vacuum generation and separation combined centrally on one drive shaft, so no separate separation machines are needed on the dental units
-
Two-stage Separation: High foam tolerance; aspiration of secretions and blood foam into the turbine space is reliably prevented
-
Corrosion Protection: Galvanic coatings on housing parts and runners for an exceptionally long service life
-
Quiet Running: Aerodynamic turbine wheels and integrated sound suppressors
-
Auxiliary Air Valve: Integrated auxiliary air valve regulates suction power and ensures internal cooling
-
Flow Accelerator: Optional “tidal wave” flow accelerator flushes the pipe system to prevent deposits and odours
-
Care: Use Orotol® plus with MD 555 cleaner to prevent deposits and blockages; DürrConnect installation system available
