Amalgam Separator User Manual Breakdown Air Techniques Acadia: Part 2 Installation

Amalgam Separator User Manual Breakdown Air Techniques Acadia: Part 2 Installation

Today we will be continuing the installation segment for the Air Techniques Acadia brand of amalgam separators. Part 1 of this blog highlighted the recommendations for the pre-installation and assembly of their Acadia amalgam separator.


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.

Acadia Installation

The installation of the Acadia is much easier than assembling the system. Though the instructions are rather wordy, they do have easy to follow diagrams that make it quite clear on what needs to be done to install this system. Air Techniques makes it very clear, that an amalgam separator is to be installed before the pump, never after.


The Acadia can be either wall mounted or installed on the ground, based on the requirements of the installation. Air Techniques have broken their installation guide into three segments;

1) Acadia Inlet installation

2) Dry vacuum installation

3) Wet vacuum installation

Inlet from Chairs

Unfortunately, Air Techniques has made the assumption that the average office has a 1 ½” inlet trunk line from the operatories, which a closeout adapter already installed on the pipe. This would only be true for offices with a dry vacuum system, as it is not recommended to have a trunk line smaller than 1 ½” when installing a dry vacuum in a dental practice.

The fact is, most offices are small and have a wet vacuum system, usually having either;

– 1” PVC or Copper

– 1 ¼” Copper (usually found in practices in older buildings)


If you are not a master plumber but want to install you want to bring your lines up to a 1 ½” to fit on the Acadia, simply go to your hardware store and purchase a rubber coupler. These rubber couplers come in all different sizes, giving you the ability to combine almost any two sized pipes or hose together.


Many M.A.R.S Certified Amalgam Separator Specialists use the rubber couplers to seal up the Acadia’s inlet and outlet when they are recycling the whole unit after upgrading an office to the no maintenance LibertyBOSS.

Dry Vacuum Installation

For a dry vacuum pump, the installation of almost any amalgam separator if fairly simple. M.A.R.S has done a blog series on how to properly install any amalgam separator on a dry vacuum pump. Essentially, you connect a 1 ½” hose from the amalgam separator’s outlet to the pump’s inlet.

In this diagram, Air Techniques shows the Acadia being mounted. M.A.R.S feels the location of the amalgam separator should depend on the location of the mechanical room. Read the blog mentioned earlier to learn more about choosing the right location of installing an amalgam separator on a dry vacuum pump.

Wet Vacuum Pump

It is common knowledge that most single head wet vacuums have ¾” inlets and most double headed wet vacuums have a 1” inlet (with the exception of the Midmark system that has a 1 ¼” inlet). The design on the Acadia does not allow for other sized hoses to be used on the system, this is why the use of rubber couplers and bushings are necessary to complete the Acadia Installation to a wet vacuum system.

Common Mistakes

Please note that there are some common mistakes made by Service Technicians, Plumbers, and Dentists when installing an amalgam separator.

Installed Backwards

As anyone can imagine, a system installed backward will not function as intended. In the photo below a plumber was confused on the installation of the SolmeteX Hg5® and installed the system backward.

An easy way to avoid this mistake is to remember amalgam separators work on sedimentation, the inlet of every amalgam separator is at the top, and the outlet is at the bottom.


Solids Collector

The solids collector of a suction pump has nothing to do with amalgam separation; it is the last line of defense for your suction pump. It is meant to protect your pump’s warranty in case any material was to by-pass the amalgam separator.

If you are like many Dental Practices that have improperly located a solids collector in front of your amalgam separator, you should be handling and disposing of the solids collector as toxic waste, adding to your amalgam separator costs. Had the amalgam separator been located before the solids collector, the material in the solids collector would be considered sewer safe, which saves the Dental Practice on the disposal fees.

Chair to Mechanical Room TWO

Unfortunately for the Acadia, this system has a built-in solids collector on its inlet. This is the only amalgam separator that has two built-in disposal costs, the inlet solids collector and the sedimentation filter.

Disposal points

Our next blog will be discussing the proper handling and disposal of both parts of this system.

Next Blog

Due to the complexity of the Acadia’s multiple user manuals and the information that is required to be shared on this unit, we will be releasing another two blogs on the Air Techniques Acadia; – Inspection and Troubleshooting – Maintenance, Disposal and Notes

Unfortunately, we will have to pause the release of the User Manual blog series for a couple weeks as M.A.R.S will be attending a few conferences and we wish to share our experiences before and after each of the blogs.

On September 6-8th, M.A.R.S will be attending both the California Dental Association meeting in San Francisco and the International Academy of Oral Medicine and Toxicology conference in Stowe, Vermont. From September 13th -15th, M.A.R.S will be in Columbus, Ohio exhibiting, as well as teaching multiple CE courses on infection control.
