ABSTRACT:
Dental suction apparatus is a modular construction, made up of a plurality of modules joined fluid-tight side-by side. A main suction duct extends through all of the modules. At least two of the modules have connection for suction hoses each having a suction nozzle, holders being provided on the modules for holding the suction nozzles when not in use. At least one module has a filter chamber connected between a suction tube and the main suction duct. A removable filter unit in the filter chamber has a basket-shaped filter on a stem by means of which the filter can be removed through on opening closed by a hinged cover. A cap on the stem provides a seal for the filter chamber. Flow of air from the suction tube of each suction tube module to the main suction duct is controlled by a valve in the form of a bellows provided with a telescopic guide and with a control valve for controlling the expansion and contraction of the bellows by differential pressure.
