Amalgam Separator User Manual Breakdown: Metasys Eco II – Part 2 Inspection, Maintenance, and Disposal

Today we will be continuing part two of the Metasys brand of amalgam separators. Part 1 of this blog highlighted the recommendations for the installation of the Eco II system.

Thank you for following us on this journey to learning how to read the User Manuals of the top six amalgam separators sold in North America. Our first segment started with the amalgam separator that requires the least amount of work, maintenance or inspection, the M.A.R.S LibertyBOSS.

We will be covering the required inspection, maintenance, and disposal of the Eco II.

Inspection of the Metasys Eco II

Of the amalgam separators that require regular inspection, the Eco II has introduced a system that does help make this process a little easier. In addition to providing a simple annual chart for the Eco II, they provide a MONTHLY email reminder for the inspection of their system.

To perform a proper inspection of the Eco II, you will need a flashlight and access to the Eco II. The following preventative maintenance video will provide you with helpful tips and reminders on how to properly maintain the Eco II amalgam separator.

The Purpose of Monthly Inspections

As it is with every amalgam separator, the manufacturer has set maintenance and inspection schedules for a reason. If you maintain any amalgam separator as intended by the manufacturer, you will remain compliant issue free.

Every system has an eventual breaking point, some take longer than others, but eventually, you will notice the effects if your system isn’t maintained properly. Most central amalgam separators have a built-in overflow, as to not impede the flow of air and water in the event the system is neglected.

The photo below shows an Eco II that was not properly inspected or maintained by a Dental Practice or their service company. Though this system never experienced suction loss, due to the design of the Eco II, their office was left non-compliant. The unfortunate non-compliance was all due to a misunderstanding on when the system is considered full. The photo on the right is circling the fill capacity of the Eco II; when the sediment has reached the full line or when the system has been in service for 12 months, whichever comes first, is when the Eco II needs to be changed.

Though it is rare, if you are experiencing leaking around the inlet or outlet ports of the Eco II, there may be an issue with the O-rings on the fittings.


As seen in the photo above, it is very simple to adjust the O-ring back into its groove to solve any issues of leaking or air loss. If the O-ring is broken or missing, contact PureWay for assistance.


Every amalgam separator manufacturer includes ISO Testing related information such as;

– maximum fillable volume (700 mL)
– Air pressure (300mbar = 9” Hg)
– Amalgam Separator Type (type 2 – sedimentation)
– Maintenance and Inspection Requirements (Monthly inspections, Maintenance – every 12 months or when full, whichever comes first)

(The bolded items above is the information pertaining to the Eco II amalgam separator)

Cleaning Maintenance

Though it is not mentioned in the user manual of the Eco II, every amalgam separator calls for the DAILY use of a neutral pH, non-foaming evacuation line cleaner. A process that should already be done in every office, as it is required by the Center for Disease Control – Oral Health Division.

As most amalgam separators are sedimentation based, dense material like prophy paste, varnish, oxides, and pumice will often fill the amalgam separator quickly. As mentioned earlier in this blog, the monthly inspections of the Eco II will ensure that when your system reaches its maximum capacity, you will be ready to order a new system. It is recommended to order a new Eco II when you see the sedimentation at the 95% range.


For most amalgam separators, shipping and disposal are included in the initial cost of the system. The Metasys Eco II is no different than any other amalgam separator in that regard.

When your amalgam separator is full and due for changing, Metasys provides simple and easy instructions on how to exchange your expired system with a new one. Similarly to a M.A.R.S LibertyBOSS, the Eco II has the entire system replaced, minimizing the exposure to methylmercury and other biological waste.

Below is a simple eight-step process in replacing a full Eco II amalgam separator.


After every Eco II installation, it is important for you to register your device. Once again, similar to the LibertyBOSS, registering your system will help the manufacturer assist you in ensuring your compliance.
