Adjustable Bur Speed

You regulate the speed. The Primea Advanced Air high-speed handpiece can be set to a value between 60,000 and 320,000 rpm.

With one handpiece, you can now efficiently cover the entire range of high-speed procedures: effortless opening of cavities, easy cutting of crowns and bridges, quick and safe removal of old filings, and precise finishing of preparation margins.

Constant Removal Rate

With the award-winning Advanced Air technology, loss of speed is a thing of the past.

A sensor in the head of the handpiece constantly measures the actual rotation speed of the bur on the tooth, immediately adjusting the air supply to maintain maximum treatment efficacy at all times.

What is the warranty on a Primea Advanced Air handpiece?
A-dec is pleased to offer a 2-year warranty for Primea Advanced Air handpieces purchased from an authorized A-dec dealer. See Regulatory Information, Specifications, and Warranty for full warranty information.

What are the compressed air requirements for the Advanced Air system?
90 psi input from the facility system (90-125 psi range).  Advanced Air regulator will be set at 83 psi at the factory, target range is 81 - 85 psi.  If the supply of air is poor into the operatory and compressor is undersized optimal performance will not be achieved, but the Advanced Air system will still function.

Do the Primea Advanced Air built-in electronics need to be serviced? 
The built-in electronic components do not need to be serviced separately. However, regular servicing and maintenance for your dental equipment should be completed. This will ensure the proper functioning and safety of the components. 

Can air handpieces from other manufacturers be operated in an Advanced Air System? 
The Advanced Air System primarily supports Primea Advanced Air handpieces. If you attach a standard handpiece or any other air-powered device (from W&H or other manufacturers), the system will prompt you to switch to Basic Mode and run the handpiece at a drive air supply level that might or might not be suitable for the handpiece or the application.

Do the turbines wear out faster than a typical air high-speed handpiece? 
No.  The turbines wear in the same way as a typical air high-speed handpiece. 

Does this system wear out burs faster?  
No.  Depending on use, burs may actually last longer due to the constant rate of speed and the ability to set an optimal speed vs the high rate of variability with a typical air high-speed handpiece.
