What if there were a quick and simple way to anticipate what would happen to static pressures if you increased or decreased airflow?

The good news is that once you measure static pressure, you can estimate fan airflow in less than 30 seconds with the right information. Once technicians understand that static pressure testing gets them to fan airflow, they will see why it is important to measure it on every call.

You might wonder, “Why can’t I just use a duct calculator and tape measure to identify duct repairs?” You could, but that means making a lot of assumptions and wasting valuable time.

Airflow balancing has typically been limited to commercial HVAC, but there is a growing demand and opportunity to bring this practice to residential HVAC.

Airflow is a general term that’s easy to misinterpret. When I first learned about airflow, I had to classify it into four values that made sense to me. The easiest options are the measurement location or source of the airflow reading.

The product features include thermal dispersion flow and temperature sensors; factory-calibrated controller in nonvolatile, erasable, programmable, read-only memory; and factory-mounted 24-V modulating actuators.

The DAFA can monitor radon mitigation systems by detecting a loss of airflow in the pipe and providing a signal to the homeowners if the fan has stopped operating.

Intended for commercial and residential buildings, the regulator allows only the required amount of air into a given space.

Several months ago, I wrote a Duct Dynasty article titled “Four Steps to Optimize a Duct System.” Since then, I’ve received numerous requests to expand on the simple calculations I mentioned that can help you estimate room airflow with a customer’s input.

The air duct calculator, or “ductulator,” is a commonly used tool for designing and installing duct systems. Unfortunately, many designers and technicians receive limited instructions on its correct use.
