Dayton 6366461 Replacement Blower Wheel

The Dayton 6366461 is a new replacement blower wheel designed for specific Dayton fan assemblies. It features a closed base construction and a 3/4 in bore diameter. This part restores airflow in compatible heating, ventilation or air-handling units.

Sustained airflow with closed-base design

The closed-base wheel maintains consistent air movement during continuous operation because the blades are fixed to a solid hub. This structure resists flexing under steady load so the volume of air delivered does not drop off as the motor warms up.

Direct fit for listed Dayton models

Installation consists of removing the old wheel, sliding the new wheel onto the 3/4 in shaft and securing the set screw. The wheel matches Grainger part numbers 3ATU4, 3ATU5, 3ATU6, 3GY66, 3GY70, 4YU97, 4YY18, 5DVN1, 5PV07 and 6KWK3. Builders working on other brands or unlisted Dayton models will need a different wheel.

Questions about this item

How much power does the 6366461 blower wheel draw when running continuously?

The blower wheel itself has no motor and draws no power; consumption depends entirely on the motor it is mounted to.

Which existing motor shaft and housing does this wheel need to fit?

It requires a 3/4 in bore on the motor shaft and is designed for the closed-base housings used on the listed Dayton models.

Will this wheel work on the older Dayton 3ATU4 and 3ATU5 blowers I already have?

Yes, the 6366461 is a direct replacement for the 3ATU4, 3ATU5, 3ATU6, 3GY66, 3GY70, 4YU97, 4YY18, 5DVN1, 5PV07 and 6KWK3 units.
