Application and Airflow

This Dayton OEM blower is a direct-drive unit built for high-temperature environments. It delivers 151 cfm at zero static pressure and maintains 140 cfm at 0.100 in SP. The forward-curved wheel suits equipment cooling and industrial air movement where a compact, assembled fan is required.

Fit and Limitations

The blower suits installers needing a 230V AC direct-drive fan with a 3 7/8 in wheel for confined spaces. It is not for buyers who require airflow data at 0.125 in SP or 0.375 in SP, or those needing a belt-driven configuration for adjustable speed.

Static Pressure Performance

Airflow drops to 134.4 cfm at 0.250 in SP and 120 cfm at 0.400 in SP, reaching 110 cfm at 0.500 in SP. These points define whether the blower can overcome the resistance of your specific duct or enclosure.

Questions about this item

What voltage standard does the 230V AC blower use and what airflow does it deliver at zero static pressure?

The blower runs on 230V AC single-phase power and delivers 151 cfm at .000 in SP.

What wheel diameter and drive type determine whether this blower fits the existing housing?

It has a 3 7/8 in forward-curved wheel and a direct-drive motor with no separate drive package.

How is the assembled blower installed and which wiring step is often missed?

Mount the assembled unit, connect the 230V AC supply to the motor leads, and verify rotation matches the airflow arrow — reversing the leads is the common error.
