Dayton 1TDT2 Blower Application

The Dayton 1TDT2 is a rectangle replacement OEM blower rated at 549 cfm at zero static pressure. It uses a forward-curved wheel and direct-drive design for high-temperature environments. The unit arrives fully assembled and ready for installation.

Suitable Uses and Limitations

This blower suits OEM replacements where a 6-1/4 inch wheel and direct-drive airflow are specified. It is not for installations that require a drive package or different wheel geometry. Buyers needing airflow ratings at intermediate static pressures not listed should look elsewhere.

Airflow at Static Pressure

At 0.000 in SP the blower delivers 549 cfm, dropping to 538 cfm at 0.100 in SP and 507 cfm at 0.250 in SP. Higher resistance points show 480 cfm at 0.400 in SP and 450 cfm at 0.500 in SP. This curve determines whether the part matches the system requirement.

Questions about this item

Does the Dayton 1TDT2 blower ship fully assembled or do I need to add a drive package?

The unit arrives assembled; the specifications list the drive package as not applicable, so no separate drive components are required.

The spec sheet shows several static-pressure points — which airflow figure should I use for sizing?

Use the 549 cfm at 0.000 in SP for free-air reference, then match your duct static pressure to the nearest listed point — 538 cfm at 0.100 in, 507 cfm at 0.250 in, 480 cfm at 0.400 in, or 450 cfm at 0.500 in.

What does the 549 cfm rating mean once the blower is installed in a real system?

It represents the maximum airflow at zero static pressure; actual delivery drops to 538 cfm at 0.100 in SP, 507 cfm at 0.250 in SP, 480 cfm at 0.400 in SP and 450 cfm at 0.500 in SP as duct resistance increases.
