More compressed air for dental laboratories |  |
The increasing use of CAD/CAM systems and their successful integration into dental laboratories has lead to a rise in demand for compressed air. This growth in demand can be efficiently met by a Kaeser Aircenter system which requires minimal space, planning and installation costs, and delivers a reliable and efficient supply of quality compressed air. When installing a CAD/CAM system in a dental laboratory, consideration should be given as to whether the system requires a compressed air connection. If so, as is usually the case, then the compressed air performs a multitude of important tasks: For example, it ensures perfect tool changes, holds the milling cutter securely in place in the chuck, can be used to blow work areas clean and ensures appropriate workpiece cooling. All of these characteristics are essential to achieve perfect results when performing high-quality bridge- or crownwork (Fig. 1). However, the increased compressed air demand from a dental laboratory’s CAD/CAM system cannot be simply met by an additional or larger reciprocating compressor. The main aim of course is to provide the air-intensive milling machine with a continuous supply of compressed air – preferably around the clock, including weekends. Such requirements preclude longer periods of compressor downtime, such as for cooling, or for regeneration of the compressed air dryer. A rotary screw compressor however, generally designed for continuous operation, can meet these stringent requirements without any problems whatsoever. At the heart of the Kaeser Aircenter (Fig. 2) lies an optimised SX or SM series
rotary screw compressor from Kaeser. Delivering even more air than their predecessors, the SX 3 to SM 15 models produce 340 to 1500 l/min of compressed air at 7.5 bar. A refrigeration dryer, which is thermally shielded from the compressor, and a micro- /activated charcoal filter combination ensure a dependable supply of dry, clean and oil-free compressed air. A 200 or 270 l compressed air receiver serves as a reservoir and is integrated into a single compact enclosure with the compressor and dryer to create an all-in-one compressed air system.
The model featuring the SM 12 rotary screw compressor is also available as an “SFC” variable speed drive version. This option enables compressor performance to be flexibly adjusted to suit the widely fluctuating compressed air demand that is so often associated with dental laboratory applications. The larger systems are not only able to supply the CAD/CAM system with treated compressed air of the required quality, but are also able to meet the entire dental laboratory's compressed air needs. This provides peace of mind regarding the presence of humidity in the compressed air, which of course can negatively impact all production processes – especially dental sandblasting – and results in greater expenditure on labour and materials.
Effective sound proofing and low motor speeds ensure super-quiet performance and sound levels can be reduced to as little as 60 to 65 dB(A). As many dental practices are now often located in residential buildings, it is important that the compressors are not only quiet, but also generate as little vibration and structure-bourne sound as possible. This is particularly important for 24-hour applications. Kaeser’s “Aircenter” models fulfil all of these requirements and provide the perfect solution whatever your dental compressed air needs.
