Shaft for Dayton Blowers

This Dayton 1818 shaft is designed as a direct replacement component for compatible blower assemblies. It serves maintenance technicians and RV owners who need to restore airflow in heating, ventilation and air conditioning systems. The part matches the original equipment specifications for fit and function.

Mechanical fit and compatibility limits

Installation is limited to blowers that accept this specific shaft design and the listed Grainger part number 5NRD7. It will not work with units that require a different diameter, length or mounting configuration. Verification against the original equipment manual is necessary before purchase.

Capacity and service life

The steel construction handles the rotational loads and vibration typical of RV blower motors under continuous operation.
