OEM Blower for High-Temperature Air Movement

The Dayton 1TDR5 is a rectangular blower built for original-equipment installations that demand steady airflow at elevated temperatures. Its direct-drive motor runs at 1350 RPM without belts or couplings, reducing maintenance points in continuous-duty systems. The forward-curved wheel delivers 312 cfm at free air and holds 304 cfm at .100 in SP, 262 cfm at .250 in SP and 210 cfm at .400 in SP. The steel housing resists deformation in harsh environments.

Suited for OEM Integration Not Standalone Room Use

This unit fits machinery builders and maintenance teams replacing a specified blower in ovens, dryers or dust collectors where the mounting pattern and performance curve are already validated. It arrives fully assembled for direct fitment. Buyers needing a finished ceiling fan with decorative housing, speed controls or quiet operation for occupied spaces should look elsewhere. The design prioritises industrial airflow over acoustic comfort.

Forward-Curved Wheel Defines the Pressure Curve

The wheel geometry determines how airflow responds to rising static pressure in the duct or enclosure. At .500 in SP the blower still moves 142 cfm, showing usable output through restrictive paths. Select this model only when the system curve matches these plotted points; a different wheel type would shift the entire performance envelope.

Questions about this item

Which airflow rating should I use when sizing ductwork for this blower?

Use the 312 cfm rating at 0.000 in SP for free-air delivery, or 304 cfm at 0.100 in SP, 262 cfm at 0.250 in SP, 210 cfm at 0.400 in SP, or 142 cfm at 0.500 in SP depending on your system's static pressure.

What does the 1350 RPM rating mean for actual airflow in my installation?

The motor runs at 1350 RPM direct drive, delivering 312 cfm with no restriction; airflow drops to 304 cfm at 0.100 in SP, 262 cfm at 0.250 in SP, 210 cfm at 0.400 in SP, and 142 cfm at 0.500 in SP as duct resistance increases.

What drive type does this blower use and how does it affect maintenance?

It uses a direct-drive arrangement with no belts or pulleys, so the motor shaft turns the wheel directly, eliminating belt wear and tension adjustments.
