The dental compressor provides compressed air In one aspect, the unit may be operated as follows. The dental compressor provides compressed air to the dental chairs. An accumulator can be incorporated into the unit to store compressed air, if necessary. The compressed air is connected by associated fittings and plumbing to the water reservoir and the delivery system connections to provide compressed air to the dental air compressor, air/water syringe, and other items requiring compressed air. The compressed air and water supply subsystems connect to the existing dental chair delivery system so no change is necessary in the existing design or fabrication of these items. The water reservoir may be an autoclavable container that will be capable of accepting any water, tap, sterilized, buffered, etc. An optional piece of equipment will allow the dentist to use standard sterile water bags. The oilless air compressor output will be sufficient to operate an air driven hand piece in addition to the auxiliary devices mentioned above. For example, the output may be used to supply an air/water syringe, etc. A pressure regulator is incorporated into the unit to control the supply pressure to the dental chair. A pressure sensor monitors the air pressure to the dental chair. A pressure switch turns the compressor ON and OFF to maintain a constant supply pressure. The waste container is connected to the vacuum pump and has connections for the HVE and saliva ejector devices. The controller activates the vacuum pump on demand. The controller can activate the vacuum pump using one of several possible methods, including but not limited to, sensing the line pressure in the vacuum lines, responding to an electrical switch connected to the HVE and saliva ejector control valves, or responding to operation of a foot switch. In summary, the dental compressors provide an exemplary self-contained dental chair constructed of a dental chair and integrated compressor, vacuum pump, controller, accumulator (if needed) and associated connecting fittings, tubing and electrical wiring, water and waste containers, and sensors and controls.
