  • Design Considerations for Airflow Measurement
    Ventilation is the process of bringing air from outside a building inside, distributing it, and later expelling the air outside. One of the easiest and most effective ways to improve indoor air quality is have accurate measurement and greater control of the ventilation system. The quality of the air we breathe in the workplace plays […]
  • Fume Cupboard Exhaust Control
    Perhaps the most important health and safety control measure in PC2 wet laboratories is the fume cupboard. Opening and closing a sash will normally cause a major disturbance on airflow systems that require a fast response to maintain stability and precision. Speed of Response As an operator moves the fume cupboard sash, the control system […]
  • Supporting Safer Indoor Environments
    As the COVID-19 pandemic has demonstrated, Australia’s indoor environments require better resilience against airborne infection transmission. The single best recommendation we can give owners is to consider commissioning when developing your next project. As an example in schools, you can achieve improved cognitive function, reduced asthma symptoms, and less missed days by improving ventilation, filtration […]
  • Pressure Dependent Vs Pressure Independent Control
    Pressure Dependent Applied using blade dampers Advantages Straightforward, simple design Low cost of controls Minimum requirement Disadvantages Stability is compromised because the system is pressure dependent. Changes and fluctuations create improper flow rates and pressurization problems. Rebalancing is required at every damper location when changes are made, or fan system performance degrades.The system must be […]
