SPEEDAIRE 114X48 Regulator Diaphragm

SKU CH-N28R-SG3VT

Regulator diaphragm compatible with Speedaire compressors and multiple Grainger part numbers

  • Compatible with multiple Speedaire compressor models
  • Direct replacement diaphragm for regulator assemblies
  • New condition ensures reliable pressure control
  • Fits Grainger part numbers 4ZK94 through 4ZL02
  • Designed for Speedaire air compressor systems

Direct Replacement Part

The SPEEDAIRE 114X48 regulator diaphragm fits compatible Speedaire compressors. It matches Grainger part numbers 4ZK94 through 4ZK99, 4ZL01, 4ZL02, 4ZM21, 4ZM22 and 4ZM23. Maintenance teams use it to restore pressure control on listed models.

Steady Pressure Regulation

Under continuous operation the diaphragm maintains consistent regulator response. It cycles with the compressor without pressure drift during extended runs. The material resists fatigue from repeated flexing over long shifts.

Low Heat And Quiet Operation

The flexible membrane generates minimal friction heat during normal cycling. It adds no audible noise beyond the compressor itself. Power draw remains unchanged because the part is purely mechanical.

Questions about this item

Does the 114X48 diaphragm generate any noise, heat or power draw when the compressor runs all day?

The diaphragm is a passive sealing component; it creates no noise, heat or electrical load of its own.

Which regulator bodies must I already own for the 114X48 diaphragm to fit?

It fits Speedaire regulators that use Grainger part numbers 4ZK94 through 4ZK99, 4ZL01, 4ZL02, 4ZM21, 4ZM22 and 4ZM23.

Will the 114X48 diaphragm work in an older Speedaire compressor that still uses the original regulator?

Yes, provided the original regulator matches one of the listed Grainger part numbers.
