  • Sleeve bearings and 104 °F max inlet temperature suit continuous duty

Purpose and fit

The Dayton 1TDU4 is a rectangular transflow blower designed for OEM equipment that requires a compact, direct-drive air mover. Its forward-curved wheel delivers 105 cfm at free air and maintains useful flow at modest static pressures, making it suited for appliances, enclosures or ducting where space is limited.

Sustained airflow behaviour

At 2736 RPM the blower produces 87 cfm against 0.100 in wc and 60 cfm at 0.200 in wc, dropping to 19.1 cfm at the maximum rated 0.250 in wc. The sleeve bearings and 104 °F inlet-temperature limit mean continuous duty is practical within those pressure and thermal boundaries.

Construction and connections

Both wheel and housing are formed from C45 carbon steel, giving a rigid, corrosion-resistant assembly that arrives fully assembled. The single-inlet, rectangular outlet measures 1 in high by 7.1 in wide, allowing direct mounting to ductwork or equipment panels without additional adapters.

Questions about this item

How loud does the 2736 RPM blower run and how much heat does it add to the enclosure?

The unit moves 105 cfm at zero static pressure and 87 cfm at 0.100 in wc, so airflow remains strong enough to limit internal temperature rise; sleeve bearings keep mechanical noise low at this speed.

What power supply and mounting hardware must I already have to install this direct-drive blower?

It requires a single-phase mains supply matching the motor rating and a rectangular cut-out that accepts the 1 in outlet height and 7.1 in wheel width; no additional drive components are needed.

Will this C45 carbon-steel blower mate with my existing ductwork that uses a 1-inch rectangular outlet?

Yes, the outlet shape is rectangular with a 1 in height, and the housing is also C45 carbon steel, so it connects directly to matching duct flanges without adapters.
