The new generation ‘Aircenter’ series from KAESER KOMPRESSOREN

Compressed air users in the dental sector have always benefited from quiet, vibration-free compressed air production, treatment and storage with KAESER’s compact ‘Aircenter’ systems. Completely redesigned and featuring the very latest technology, this proven product range has been further enhanced to provide unrivalled user advantages and exceptional performance: The new generation ‘Aircenter’ series from KAESER KOMPRESSOREN redefines turnkey compressed air systems.

The proliferation of implantology and increased merging of dental laboratories with practices is leading to the creation of ever-larger group practices with significantly increased compressed air demand. This is where KAESER’s ‘Aircenter’ packages really come into their own, as they require minimal space and ensure a reliable and cost-effective source of application-specific compressed air. In addition, planning and installation costs are also significantly lower compared with conventional systems. However, with Kaeser’s new ‘Aircenter’ models, the advantages don’t stop there …
At the heart of every ‘Aircenter’ package is a compact SM rotary screw compressor, which has also been redesigned and optimised: With free air deliveries of 800, 1200 and 1500 l/min at 8 bar respectively, the SM 9, 12 and 15 each deliver even more compressed air than their predecessors. Furthermore, the SM 12 can be equipped with KAESER’s “SFC” variable speed control, allowing compressor performance to be precisely matched to suit fluctuating compressed air demand. An integrated refrigeration dryer ensures reliable compressed air drying and is thermally shielded to prevent exposure to heat from the compressor package. The use of a micro-/activated-carbon filter combination ensures exceptional compressed air quality and dependability, whilst the addition of a sterile filter installed directly upstream from the air-consuming equipment enhances air quality still further. The compressed air is stored in the 270-litre air receiver installed beneath the compressor.
All three modules – the compressor, dryer and air receiver – in KAESER’s new “Aircenter” packages are enclosed within a single housing, so that the whole system appears as one unit. In keeping with the turnkey design, all “Aircenter” systems are ready for immediate operation once the unit has been connected to the mains supply and compressed air network.
The striking anthracite-coloured housing cover on the front left of each unit is easy to remove and allows excellent component accessibility. Combined with outstanding ease of maintenance, each “Aircenter” model represents the very latest advances in air system performance and design. Every unit uses a flow optimised “SIGMA PROFILE” fluid-cooled airend and a EU EFF1-rated motor to guarantee excellent specific power with high energy-efficiency. The motor and airend are connected via a V-belt drive system equipped with an automatic tensioning device.
In addition, the units’ sound levels of 64 or 65 dB (A) are approximately 5 dB (A) lower than previous models as a result of highly effective sound insulation and low airend speeds. Moreover, a high-efficiency cooling system provides the motor and fluid / compressed air coolers with fresh cooling air drawn in from the ambient surroundings to achieve exceptionally low compressed air discharge temperatures.
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-borne sound as possible. KAESER’s new ‘Aircenter’ models fulfil all of these requirements and are the perfect choice for use in larger dental practices. ‘Aircenter’ versions with free air deliveries ranging from 313 to 540 l/min are also ideal for smaller practices. 
The internal “SIGMA CONTROL BASIC” controller provides automatic system monitoring and precisely adjusts compressor performance to match actual compressed air demand.
