Air Change System for Laboratory


Specialised in Air Change System for Laboratory 

Laboratories can be a dangerous places because toxic chemicals, flammable solvents, corrosive acids, harmful organisms and obnoxious vapours are handled on the work benches.   Most of the time, LEV (Local Exhaust Ventilation) system and PPE are in place to protect the laboratory personnel.  However, some application like handling of cadaver in formalin, chemical storage room and processing of strong flavouring as example, LEV and PPE may not be sufficient.   In this case, air change system or simply general exhaust ventilation system are utilise in laboratory to constantly dilute the concentration of contaminants.

Air change per hour, or air change rate, ACH or ACPH, is a measure of  the air volume added to or removed from a space divided by the volume or the space.  If the air in the space is either uniform or perfectly mixed, air changes per hour is measure of how many times the air within a defined space is replaced.

Basically, there are ducted and ductless (Filtration System) air change system available to tackle the air quality in the laboratory.   The solution is vary from laboratory to laboratory, it is depending on various factors :

  • Laboratory size (area and volume)
  • Facility Layout and workflow
  • Temperature and relative humidity
  • Number of air changes required
  • Make up air or existing HVAC system (split air-cond or AHU)
  • Type of vapours and particulates
  • Filter required (type and position)
  • Available budget
  • Regulatory compliance
  • Energy consumption and more

We are specialised in both ducted and ductless air change solution for laboratories.
