Frequently asked questions

Why are Dwyer Magnehelic gauges commonly used in HVAC systems?
Magnehelic gauges provide simple, reliable measurement of low differential pressures in air handling and filtration applications.
What is the purpose of differential pressure monitoring across air filters?
Differential pressure readings indicate filter loading and help determine when filter replacement is required.
How do I select the correct pressure range for a Dwyer gauge?
The gauge should be selected so normal operating conditions fall within the most accurate portion of the measurement scale.
