Laboratory Ventilation & Dust-Free Relief Air Systems


MARC Technologies has been involved in advanced extraction system design for many years. Its important to understand that a laboratory environment is one of the most hazardous on a mone site and needs well balanced extraction and air supply systems – without enough air extraction systems will not work.

A few very important notes: 

  1. Fume cupboards 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 is usually extremely carcinogenic due to the presence of aggressive mineral acids: Fresh air introduction is crucial and is also stipulated in the Australian laboratory design standard AS/NZS 2982!
  3. Air being pulled out of a lab 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 equipment when you’re probably analyzing your site’s dust that’s being sucked into your lab?
  4. There are ways of reducing the amount of air extracted from your lab: You can reduce the amount of air extracted from your lab 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: MARC can help you feed clean filtered air into your laboratory 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.
