These are Figure 11 Outlet Chamber Air Flow Grids are portable test equipment that indicate face air velocity on grills, diffusers, registers, exhaust hoods, coils, filters, dampers and similar restrictions. Measuring airflow is crucial to ensure optimal comfort, energy efficiency, and equipment performance. Tips Jan 23, 2015 · Martin Holladay | Jan 23, 2015 09:53am | #2. We start with the basics of pressure, temperature and air flow testing and build up to more complex air balancing techniques. However, the cost. It provides reliable data with precise calculations of the overall volume flow in HVAC systems.
