Laboratory & Gold Room Ventilation & Dust-Free Relief Air Systems


MARC Technologies has been involved in advanced extraction system design for many years.

It’s important to understand that laboratory and gold room environments are potentially the most hazardous on a mine site and so need well engineered & balanced extraction and air supply systems.


A few very important notes: 

  1. Fume cupboards and extraction systems in general need air to breathe: Their fans are usually more powerful than smaller extraction system fans like AAS extraction fans, ICP-OES extraction fans, etc. In fact we see outside air being sucked into the lab in more situations than you would expect – resulting in human exposure (and expensive equipment) to hazardous fume.
  2. If allowed to accumulate, the air in a typical mine site lab or gold room is usually extremely carcinogenic due to the presence of aggressive mineral acids: Fresh air introduction is crucial and – for laboratories – is also stipulated in the Australian laboratory design standard AS/NZS 2982! 
  3. Air being pulled out of a lab or gold room via the many extraction systems will need to be replaced: It’s a law of physics – in that process dirt and dust will find its way in which results in contamination, dirty equipment and potential inhalation. What’s the point of having expensive analytical equipment when you’re probably analyzing your site’s dust that’s being sucked into your building?
  4. There are ways of reducing the amount of air extracted from your lab or gold room: You can reduce the amount of air extracted from your building by as much as 70% by using a few techniques, engineered extraction hoods, etc.  
  5. There are cost-effective ways of filtering the air that is supplied to your lab or gold room: MARC can help you feed clean filtered air into your building in a variety of ways to suit your budget.  We can positively pressurize your lab with self-cleaning filtered air supply systems where you will not have to clean any filters for between 2 and 5 years…maybe more!  Obviously this statement is dependent on site specific conditions.
