How often does the TWIN Care Set need to be replaced?

The consumption volumes for each instrument are 0.07 ml of oil and 0.07 ml of cleaning solution. This gives a maximum capacity of 2857 cycles. In reality, the value is around 2800 to 2850 cycles, as initial filling is also required and the fill quantity of the cartridges is subject to certain tolerances that are regulated by the applicable standards.

What instrument adaptors are available for the Assistina TWIN?

All adaptors that are suitable for the Assistina 3x2/3x3 can also be used in the Assistina TWIN. There is only one exception: the RM/ISO adaptor for the Assistina 3x2/3x3 is not compatible with the Assistina TWIN. Quick Connect adaptors ISO and RM can be used for the Assistina TWIN instead. An overview of all adaptors is available on the product website.

Why does the Assistina TWIN have a HEPA filter?

During the maintenance process in the Assistina TWIN, the rotating parts are lubricated with oil and the spray channels rinsed with cleaning solution. These liquids are introduced to the handpieces using compressed air, which produces aerosols that may contain potentially contaminated body fluids (e.g. blood and saliva). In order to ensure that the apparatus poses no risk to the user, the patient or third parties, the law stipulates that aerosols must be prevented from leaking out of the apparatus. We make sure of this by using active suction and the HEPA filter. This HEPA filter must of course be changed regularly, which is why the lifespan of the filter is matched exactly to the capacity of the two cartridges. The HEPA filter therefore reaches the end of its service life once one set of cartridges has been used.

How does the user know when the TWIN Care Set needs to be replaced?

The intelligent process monitoring system documents the number of maintenance cycles that have been performed, thereby automatically calculating the number of instruments that can be serviced with the remaining quantity of fluid. The user receives an alert 300 cycles before the cartridge needs replacing (the oil and cleaner LEDs on the top of the unit turn yellow in colour).

How do you replace the TWIN Care Set?

The two cartridges and the filter can be changed easily without any tools. As with the Assistina 3x2/3x3, the fluid is supplied via tapping needles in the bottom of the cartridge spaces that penetrate the cartridge membrane, thereby drawing the fluid out of the cartridge. The two cartridges have different shapes to ensure that the two fluid types cannot be mixed up. In addition, it is only possible to install the HEPA filter incorrectly by using force, which is not necessary.

Why is there no rotational lubrication option in the Assistina TWIN?

The oil is atomized in the Assistina TWIN before it is enters the instrument. This ensures full coverage of the gear parts, eliminating the need for technically complex and time-consuming rotational lubrication. However, there is no negative impact on the maintenance quality: the results of a maintenance operation correspond to those achieved with the Assistina 301 Plus.

What does HEPA mean, and what is filtered out of the air?

HEPA is short for 'High Efficiency Particular Air', and the filter is classified as HEPA class E11. This means that the filter retains all particles larger than 1 µm, which includes, among other things, a wide range of bacteria and viruses, suspended particles such as dust and respirable aerosols.

Oil service without waiting time

Green light for better sustainability: with the Assistina Twin, waiting times during lubrication are a thing of the past. It is the first processing device equipped with two alternately usable process chambers, thus enabling non-stop loading. Prepare your transmission instruments easily and more efficient than ever!

Runs like a charm

1 Assemble the instrument in chamber 1.
2 Close chamber 1 and start the process.
3 Assemble the second instrument and close chamber 2 as soon as the process in chamber 1 is complete.
4 Remove the instrument from chamber 1 and repeat steps 1 and 2.

Oil service in record time

With the Assistina Twin, you can maintain your instruments more quickly than ever before. Thanks to the innovative oil nebulization technology, W&H has succeeded in decreasing the maintenance process to a record time of just 10 seconds – for a speedy and incomparably thorough maintenance result.

An innovative system

The oil is nebulized before being blasted through the instrument at high pressure. This removes soiling from the inside of the instrument even more effectively. Thanks to the fine mist, every single part of the gear is wetted without having to set the gear parts into motion. All aerosols are removed from the process chambers through active suction and an integrated HEPA filter.

Practical for every practice

The Assistina Twin can be tailored to meet the individual needs of your dental practice. It can process up to 360 instruments per hour not just due to the innovative procedure with a short processing time, but also thanks to its ergonomic design and wide range of adaptors.

Groundbreaking technology

- Minimum consumption
  
  Maximum lubrication with minimum consumption
  
  Thanks to the smart process monitoring, the Assistina Twin always achieves thorough maintenance with minimum consumption. The Assistina Twin Care Set only needs to be changed after around 2,800 instruments. Your instrument maintenance is thus not just quick and reliable, but also more cost-efficient than ever.
