Dayton 1TDR8 Rectangular OEM Blower

The Dayton 1TDR8 is a rectangular OEM blower designed for high-temperature environments. It operates at 1550 RPM with a single-phase direct-drive motor and a steel forward-curved wheel. The unit arrives fully assembled for immediate installation. It delivers 358 cfm at .000 in SP and maintains 280 cfm at .500 in SP.

Suited for high-temperature industrial ventilation

This blower suits facilities that need reliable air movement in elevated heat conditions. The direct-drive construction reduces maintenance compared to belt-driven alternatives. Buyers who require variable-speed control or belt-drive flexibility should look at other configurations. The single-phase power input limits use in three-phase-only electrical systems.

Airflow performance at static pressure

The blower provides 358 cfm at .000 in SP and 350 cfm at .100 in SP. At .250 in SP airflow reaches 321 cfm, dropping to 300 cfm at .400 in SP and 280 cfm at .500 in SP. These figures determine whether the unit can overcome the duct resistance in your application.

Questions about this item

What power supply and mounting setup does the 1550 RPM direct-drive blower require?

The blower runs on single-phase mains voltage and is direct-drive, so no belt or pulley kit is needed; you must provide a compatible 1-phase electrical circuit and a secure mounting surface for the assembled steel housing.

Will the 6 1/8 in forward-curved wheel deliver the listed 358 cfm at .000 in SP when paired with an older duct run?

At zero static pressure the blower moves 358 cfm; at .100 in SP it drops to 350 cfm, at .250 in SP to 321 cfm and at .400 in SP to 300 cfm, so an older duct that adds resistance will reduce airflow according to those points.

How can I verify the blower is performing to spec after installation?

Measure the airflow or static pressure in the system; if you read roughly 358 cfm at .000 in SP, 350 cfm at .100 in SP, 321 cfm at .250 in SP or 300 cfm at .400 in SP the unit is operating within its published curve.
