Amalgam Separator User Manual Breakdown: Metasys Eco II – Part 1 Installation

Amalgam Separator User Manual Breakdown: Metasys Eco II – Part 1 Installation

Today we will be reviewing a European amalgam separator out of Austria, the Metasys Eco II, and Eco II Tandem.

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 last segment started with the amalgam separator that requires the least amount of work, maintenance or inspection, the M.A.R.S LibertyBOSS.

The Metasys Eco II is a compact and elegant European designed amalgam separator, specifically intended to fit the tight mechanical rooms of the European Dentist. Similar to the M.A.R.S LibertyBOSS, Metasys has only one type of amalgam separator. Unlike the LibertyBOSS, due to the small stature of the Eco II, Metasys has designed a kit that will combine two Metasys Eco II systems to service larger Dental Practices.

The Eco II is a simple amalgam separator that requires fewer inspections than the average system. Where confusion typically lies with the Eco II amalgam separator, is sizing appropriately for the practices and knowing when to use the Eco II or the Eco II Tandem. Today’s blog will go through the user manual of the Metasys’ Eco II, offering insight on the Eco II user manual.

Metasys Eco II User Manual

The Eco II has a well laid out user manual, for the most part, is clear and easy to follow. The only downside to the manual, since it is a European system, some of the information has been left in metric, not being converted for American users. A simple Google Conversation will solve this issue for most.

The Metasys Eco II blog series will be broken up into two parts, today we will focus on installation of the Metasys Eco II. Our next blog will focus on the inspection, maintenance, and disposal of the Eco II.


Like many amalgam separators, the Eco II has been designed for a straightforward installation in a dental practice. If you were to choose to go the route of the Metasys Eco II for your compliance, the following would ensure you have the appropriately sized the system for your practice and that it has been installed correctly.

Sizing your Eco II

According to Metasys Managing Director, Walter Ruffini, there are two factors to consider when choosing between an Eco II or Eco II Tandem. Those factors are;

1) Total Number of Chairs: The Eco II has been rated for up to 6 total chairs. You must include all the chairs attached to the suction line, including hygiene chairs. Amalgam separators are refined solids collectors; they are made to capture any material heavier than water. Prophy from a hygienist will fill your amalgam separator faster than amalgam.

2) The diameter of Suction Line: If the diameter of your suction trunk line from your chairs is 1 ½” or larger (essentially any office with a dry vacuum system), you are required to install an Metasys Eco II Tandem.


With the Eco II, Metasys provides some parts; the mount assembly and a variety of hose connections. The mount is the rectangular black box that the Metasys Eco II is placed, giving the option of a wall or floor mount. If you wish to wall mount the Eco II, you have to order the part from PureWay before the installation process can begin.

Similar to an Ikea assembly guide, Metasys provides straightforward diagrams and instructions to construct the Eco II mount. It is as simple as putting the two pieces together and using the supplied screws to secure it in place.

On the same page, Metasys provides simple instructions on how to attach the Eco to your vacuum line. Essentially, you choose the appropriately sized hose fittings for your current vacuum hose, cut the hose and slide the fitting into the hose, then clamp it with a hose clamp. Once you have chosen the correctly sized fitting, be sure to add the provided O-rings to each of your fittings.

Choosing Installation Location

As it is for every amalgam separator, choosing the right location in your mechanical room to install your system is very important. There are many features to consider, and each amalgam separators have different requirements. Two of the essential points to contemplate are;

* Do you have a wet or dry vacuum?

* Does your amalgam separator require inspections?

Wet – Vacuum Installation

In the amalgam separator industry, it is common practice to have an amalgam separator installed on the inlet side of a wet vacuum pump. The main reasons for this are; it allows for a better separation rate, it protects the pump from large particulates, and it does not add the cost of the solids collector to your compliance cost. What Dental Professionals have to remember, anything after an amalgam separator is considered sewer safe, anything before is deemed to be toxic. If your amalgam separator is installed after a solids collector of a pump, the solids collector will be required to be handled and disposed of as toxic waste. Though PureWay, a Partner with Metasys, does claim their system can be installed on the outlet of a wet vacuum system, they agree with the Amalgam Separator Industry, stating that the location of an amalgam separator should be located before a wet vacuum pump.

Dry-Vacuum Installation

In the past, there had been some amalgam separator manufacturer that allowed an amalgam separator to be installed either before or after the air/water separator of a dry-vacuum pump. Nowadays, this is not a common practice as it is understood that amalgam separators function better with the steady flow of inlet water from chairs than the rush of released water and sludge from a pumps air/water separator’s discharge.

The Metasys is one of the very few amalgam separator manufacturers that allow their system to be located on the outlet of an air/water separator.

After conversations with PureWay, the general tone was they agree that the location of the system would be best on the inlet of an air/water separator. They did say, if the installation does call for it, they believe their system will function adequately on the discharge side of a dry-vacuum pump.


As mentioned before, the Eco II requires less maintenance than two of the three amalgam separators we have discussed thus far in this blog series. To ensure your compliance with the Eco II, Metasys requires MONTHLY inspections, which means wherever you install your Eco II it needs to be accessible. The visual inspection of the Eco II would include the use of a flashlight to check the sedimentation level of the system.

Up Next

To properly examine the fourteen page manual of the Eco II, we have divided this series into two parts. Now that we have completed the installation of the Eco II, we will be discussing the inspection, maintenance, and disposal of the system.
