Successful dental practices require the best suction and compressed air systems, these are key to ensuring that your surgery runs smoothly on a day to day basis and gives you the dentist peace of mind when using the equipment. However, this together with pipework layout is one of the main areas which is overlooked when planning a new dental surgery and is in fact the most important element. In the unfortunate event that any problems do occur, a surgeries down-time can cost the practice both time and money.

There are two main areas of dentistry, conservation and surgical, each of these areas is described below.

Conservation Dentistry is specific to the protection of the teeth, it is therefore important to achieve high air flow and medium vacuum as this will keep the patients tooth cool and will control the spray from the tip. This in turn keeps the patient comfortable and avoids gagging, keeps the surgeons vision clear and ensures cross infection control.

Current international standards (BS EN ISO 10637) which ensure the safety of dental suction systems require the following:

  • Air Flow: Suction systems require a minimum of 250 litres of air per minute at a 16mm plus or minus 1mm aspirator tip with a maximum vacuum of no more than 250mbar. Compressor systems require a minimum of 50 litres/min at 5bar. All Cattani suction and compressed air units comply with this standard.

    Surgical Applications is specific to treating diseases, injuries and defects of the mouth, jaws, hard and soft tissue, it is therefore important to achieve low/medium air flow and high vacuum as this will remove any blood and debris from a precise area in the patient’s mouth, this ensures the comfort of the patient and keeps the surgeons vision clear during surgery.

  • Negative pressure (vacuum pulling power): The negative pressure required depends on the size of tip, the smaller the tip the higher the negative pressure required. Generally, 150mbar is accepted as good vacuum for fixed speed suction systems, the standard states a maximum of 250mbar.


    Pipework should be MUPVC type not ABS. Swept bends and ‘T’ connections with a fall from the surgery to the pump will ensure water will not collect in the suction pipework.

    If required your current system can be tested using vacuum gauges to discover the current performance of your system, air flow and suction power.

    Why Cattani systems?

    With over 50 years experience within the dental trade Cattani ESAM (UK) Ltd are specialist suppliers of high quality suction systems and oil-less compressors. Cattani UK are so confident that their systems deliver unbeatable performance, power and reliability that they offer a maximum of 3 years warranty* on their suctions systems and a 5 year warranty* on all of their compressors. All Cattani systems comply to ISO 10637.

    Choosing the correct suction and compressed air setup for your practice can be a daunting task with so many units on the market all claiming to get the job done, but other than air flow and vacuum pulling power what other features should you look out for?

    Best price doesn’t always mean a great deal, Cattani do not claim to have the cheapest systems on the market, but when compared to the competition the product development and research that goes into all of their products you can see that money really does reflect quality.

    How the system affects the environment besides air flow and power, noise levels of a unit may be important when planning the layout of a dental surgery. Cattani systems deliver some of the best and lowest noise levels of any dental unit, their single surgery Micro Smart with sound reducing cover can reduce noise levels to an incredible 41 – 48 dB(A). Noise levels can have a great impact on the environment within the dental practice, Cattani’s suction and compressed air systems offer some of the lowest noise levels in the industry.

    Just because the unit looks great from the outside does not mean that it works great on the inside, clever features to look out for are digital displays and clever programming which can make your equipment easy to use and service. Cattani Micro Smart allows the user to control the power using the remote keypad. The variable speed system allows the user to choose the ideal vacuum level for their procedure using the three presettable levels, they also monitor the vacuum level and automatically respond to changes in demand from the surgeries.
    For compressors the additional features like Teflon coated pistons and receivers ensuring food quality storage of clean dry air, requiring no replacement during their lifetime and self purging drying columns which automatically removes any moisture present in the system, are standard in all of Cattani’s compressors.
