Model / series: Magnehelic (2000)
The Magnehelic® is the classic dial gauge for low differential pressure. A magnetic linkage moves the pointer without a mechanical connection through the diaphragm housing, so it reads small pressure differences quickly and reliably with no power supply. It shows positive, negative (vacuum) or differential pressure.

Where it’s used
Our application pages place it on cleanrooms and silos and dust collectors. Typical uses are filter monitoring, fan and blower pressure, duct static pressure and keeping cleanrooms positive.
Ordering
Built to order. Tell us the range (and units), the medium, the maximum line pressure (for the MP or HP option) and the mounting (panel, surface or with a filter gauge kit), and we’ll confirm the model code and lead time.
