Application fit

The Dwyer 2230 is a new differential pressure gauge built for measuring pressure differences across filters, coils, and ducts in HVAC and industrial systems. It covers a 0-30 PSI range with 1.00 PSI minor divisions, making it suitable for technicians who need direct reading of low to moderate differential pressures in air and compatible gas applications.

Installation checks

Before ordering, verify that the process media is compatible with the gauge wetted materials and that the system static pressure stays within the rated total pressure span of -20 Inches Hg to 80 PSIG. Confirm the available mounting orientation and connection thread type match your existing pipework so the instrument can be installed without adapters.

Build and daily use

The gauge body is designed to withstand the stated pressure envelope, and the clear scale with 1.00 PSI graduations allows quick visual checks during routine balancing or troubleshooting. Standard process connections mean the unit integrates into existing test ports or permanent taps, letting technicians take readings without specialised fittings or additional tools.

Questions about this item

Does the gauge ship with any tubing or mounting hardware, or must those be purchased separately?

The supplied data lists only the gauge itself; no tubing, fittings or mounting accessories are mentioned, so plan to source any required connections separately.

Should I select the 0-30 psi model or a different range for my application?

This model is the 0-30 psi version with 1.00 psi minor divisions; choose it when your normal differential readings fall within that span and you need that resolution.

What does the 30 psi upper limit mean when the gauge is installed in a live system?

It indicates the maximum differential pressure the instrument can measure; the housing is rated for total system pressures from -20 inHg vacuum up to 80 psig, so the gauge remains safe even if line pressure exceeds 30 psi.
