  • Product typeHigh Temperature
  • OEM blower delivers 71 cfm airflow at zero static pressure
  • Direct-drive motor spins at 1580 rpm for consistent output
  • Forward-curved wheel produces 70 cfm at .100 in SP
  • Maintains 56 cfm at .250 in SP for ducted runs
  • Still moves 37 cfm at .400 in SP under higher resistance

OEM Blower for High-Temperature Use

The Dayton 1TDP4 is a rectangular OEM blower designed for high-temperature environments. It operates at 1580 RPM using a direct-drive, single-phase motor. The unit arrives fully assembled with a steel forward-curved wheel measuring 5 5/8 in diameter. This blower suits equipment builders integrating airflow into ovens, dryers or industrial cabinets.

Direct Drive and Assembled Delivery

The direct-drive design removes belts and pulleys, reducing maintenance points and mechanical noise. Because the blower ships assembled, installation time is limited to mounting and wiring the motor. No separate drive package is included or required, so the specifier avoids sourcing additional components.

Airflow Limits Across Static Pressure

Airflow drops from 71 cfm at .000 in SP to 70 cfm at .100 in SP and 56 cfm at .250 in SP. At .400 in SP the blower delivers 37 cfm, while data for .125, .375, .500, .750, 1.000 and 1.250 in SP is not applicable. Systems needing consistent flow above .400 in SP will require a different blower.

Questions about this item

How often should the forward-curved wheel and direct-drive motor be inspected or replaced?

The assembled unit has no belts or couplings to service; periodic cleaning of the wheel and a check for bearing noise are the only routine tasks, and the motor is designed to run continuously at 1580 RPM without scheduled replacement.

At what static pressure does airflow fall below the 70 cfm mark?

At 0.250 in SP the blower still delivers 56 cfm, and at 0.400 in SP it drops to 37 cfm, so the 70 cfm threshold is crossed between 0.100 in SP and 0.250 in SP.

How much heat and noise does the 1580 RPM motor produce during all-day operation?

The direct-drive motor runs at a constant 1580 RPM with no gearing, so heat rise is limited to the motor frame itself and noise stays at a steady low hum that does not increase over time.
