Rectangular OEM Blower 1075 RPM

This Dayton 1TDT9 blower is a direct-drive unit built for original-equipment installations that require a rectangular housing and forward-curved wheel. It suits HVAC technicians and facility engineers replacing or specifying air-moving components in commercial or industrial equipment. The assembled, single-phase design simplifies integration into existing ductwork or machinery.

Sustained airflow across static pressures

At zero static pressure the blower delivers 794 cfm, falling to 780 cfm at 0.100 in SP and 720 cfm at 0.250 in SP. At 0.400 in SP output is 670 cfm and at 0.500 in SP it reaches 610 cfm, showing a gradual decline rather than a sharp drop. This curve supports steady ventilation in ducted systems where resistance varies with filter loading or damper position.

Replaces forward-curved direct-drive blowers

The unit fits applications previously served by similar rectangular OEM blowers with comparable wheel diameter and direct-drive mounting. The jump is worthwhile when the existing assembly is worn, noisy or fails to meet the required airflow at the system's operating static pressure. Buyers needing a different wheel type, belt-drive configuration or higher pressure ratings should look elsewhere.

Questions about this item

How much heat and power does the 1075 RPM direct-drive motor generate when running continuously?

The blower moves 794 cfm at zero static pressure and still delivers 610 cfm at 0.500 in SP, showing the motor maintains airflow under load without published heat or wattage figures.

What electrical supply and mounting hardware must I already have to install this Dayton 1TDT9 blower?

You need a single-phase power source matching the motor and a rectangular duct opening that accepts the 8 1/4 in forward-curved wheel; the unit ships assembled with no separate drive package.

Will this 1075 RPM blower keep up with my existing ductwork that runs at 0.250 in SP?

At 0.250 in SP the blower provides 720 cfm, so it will sustain airflow through duct resistance at that pressure level.
