Time to Consider Pascals for Static Pressure Measurements, 2022-04-15

September 16,2024

Some conversations with like-minded HVAC professionals have a way of taking on a life of their own, especially when they’re from another country. I recently had a discussion with an HVAC contractor from Australia about total external static pressure (TESP) and testing the systems they install and service. As we discussed test locations and system types, I discovered all airside pressure measurements and equipment specifications our Australian friends use are in pascals (Pa)..
Is it time for our industry to consider using pascals for static pressure measurements? What would the transition from inches of water column to pascals look like and how hard would it be?
