Assembly: To assemble the maxchek backflow prevention valve, unscrew the valve and place the fram into the designated notch. Aligning the valve's peg with the fram's hinge will ensure a secure fit. Insert the slender end of the maxchek valve into your suction coupling and add your saliva ejector into the other end of the maxchek. It's that simple!

These unique, one-way autoclavable valves prevent backflow from the saliva ejector into the patient’s mouth by closing off airflow when the suction is blocked or restricted. maxchek is inserted into the saliva ejector valve and holds the saliva ejector without affecting its performance.

maxill has taken measures to ensure the product fits as best as possible with our saliva ejectors. While the fit is meant to be universal, some slight deviations in SE fit may occur. The best fit will be achieved when using maxill’s Saliva Ejectors

For easy maintenance, the aluminum valve and fram are disassembled prior to cleaning, both being fully autoclavable. The fram's are also effortlessly assembled and interchangeable.

maxchek provides a vast assortment of colours which allow your dental office to ‘colour code’ per operatory and/or procedure(s).

We encourage the use of maxill cleaning products with the maxcheck valves. Zymax products are an excellent option for cleaning these pieces. If you plan to use alternative cleaning products, please verify they won’t harm your maxcheck. Some cleaning products can cause fading.

maxchek is an essential element of every dental offices' IPAC Program. The Centre for Disease Control (CDC) reports backflow in low-volume suction lines can occur at three potential moments allowing microorganisms in the lines to be retracted into the patient's mouth: when a seal is created around the saliva ejector1 when the suction cord is positioned above the patient's mouth1 when both the LVE and HVE are 'on' simultaneously1

We understand that this is an inconvenience and are continually working with manufacturers to educate them on how MAP affects our customers.
