Rectangular OEM Blower Two Speed Operation

The Dayton 1TDT6 is a rectangular OEM blower designed for direct-drive applications. It offers two operating speeds at 1500 and 1085 RPM to suit varying airflow requirements. The unit arrives fully assembled for immediate installation. This blower suits installers needing a compact forward-curved wheel solution.

Airflow Performance Across Static Pressure

At zero static pressure the blower delivers 428 cfm, falling to 405 cfm at .100 in SP and 353 cfm at .250 in SP. Higher resistance reduces output further to 225 cfm at .400 in SP and 150 cfm at .500 in SP. The direct-drive design maintains consistent speed under load without belt losses. Performance data stops at .500 in SP with no figures for higher pressures.

Direct Drive Constraints And Chemical Notice

Direct drive eliminates belt maintenance but fixes the speed-torque relationship to the two motor taps. No airflow ratings exist for static pressures above .500 in SP, limiting use in high-resistance ducting. California Proposition 65 warnings apply for cancer and reproductive-harm chemicals. Buyers needing performance data beyond .500 in SP or variable-speed control cannot rely on this model.

Questions about this item

How much heat and noise does the 1500 RPM high speed generate when the blower runs continuously?

At 1500 RPM the unit moves 428 cfm at zero static pressure and 405 cfm at .100 in SP, so airflow remains strong under light duct resistance; direct-drive construction eliminates belt noise.

What external components are required before this 5 1/8 in forward-curved wheel blower can operate?

The blower ships assembled with direct drive, so only a 1-phase power supply matched to the motor and suitable duct connections to the rectangular housing are needed.

Will the two-speed motor (1500/1085 RPM) work with an older speed controller or thermostat I already have?

The motor provides distinct high and low speeds — 1500 RPM delivering up to 428 cfm and 1085 RPM for reduced flow — so any controller rated for the motor's phase and current can select between them.
