SKU CH-NGTX-N0ETM

A motor assembly measuring 75 inches long and 32 1/2 inches wide, compatible with Grainger part 3AA25

  • 75 in overall length fits large HVAC installations

Direct-fit motor assembly for 3AA25 systems

This Dayton HV2128800G motor assembly is built as a direct replacement for Grainger part number 3AA25 and the matching manufacturer model 3AA25. It serves HVAC installations in RV applications where the original motor has reached the end of its service life. The unit arrives new and ships directly from the manufacturer.

Seventy-five inch length

Overall length measures 75 in and overall width measures 32 1/2 in, giving a large rectangular footprint that must be accommodated in the equipment cabinet. No overall diameter or depth figures are supplied, so installers should verify clearances against the existing housing before ordering. The size determines mounting orientation and duct alignment in daily use.

Replaces worn 3AA25 motor assemblies

The jump is worth it when the current 3AA25 motor fails or shows reduced airflow and excess vibration. This assembly restores original performance without modification because it matches the listed compatible part numbers. It is not suited for systems that require a different frame size, alternate shaft configuration or higher drum capacity than the original design.

Questions about this item

What does the 75 in overall length of the Dayton HV2128800G motor assembly cap in terms of installation space?

The 75 in overall length defines the maximum linear space the assembly occupies, so the mounting bay must provide at least that much clear run.

What physical clearance does the 32 1/2 in width of the Dayton HV2128800G motor assembly require?

The 32 1/2 in width sets the minimum lateral opening; the cabinet or duct must be at least that wide to accept the unit without binding.

How is the Dayton HV2128800G motor assembly installed, and which step is most often missed?

Secure the assembly in the designated HVAC cavity using the factory mounting points, then reconnect the wiring harness; the step most often missed is verifying the harness locks fully before restoring power.
