Low-Profile Rectangular Blower 2880 RPM

This Dayton blower is a low-profile, direct-drive unit designed for OEM integration where space is limited. It delivers 262 cfm at zero static pressure using a forward-curved steel wheel. The assembly arrives fully assembled with dual 2 1/2 in inlets and a rectangular outlet. It operates on single-phase power at 2880 RPM.

Suits tight OEM enclosures.

This blower suits builders who need a compact, assembled air mover for equipment cooling or ventilation in confined cabinets. The maximum static pressure is 3/4 in wc, so it is not for installations that require higher pressure to overcome long or restrictive duct runs. Buyers needing greater airflow at elevated static pressure should consider alternative designs. The maximum inlet air temperature is 104 Degrees F.

Direct-drive forward-curved wheel determines

The single specification that decides fit is the direct-drive, forward-curved wheel producing 212 cfm at 0.100 in SP and 198 cfm at 0.200 in SP. This pressure curve defines whether the blower can overcome your system resistance. Ball bearings support continuous operation. The steel housing and wheel withstand industrial environments. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

What ducting or mounting hardware is required to install this rectangular blower?

The blower has two 2 1/2-inch inlets and a rectangular outlet measuring 1 5/8 inches high, so matching duct collars or flanges are needed for connection.

Will the 2880 RPM direct-drive motor create vibration issues on older sheet-metal plenums?

The assembled steel housing and ball-bearing motor are designed for direct-drive operation at 2880 RPM; ensure the existing plenum is rigidly braced to avoid resonance.

How can I confirm the blower is delivering rated airflow after installation?

Measure static pressure at the outlet; at 0.000 in SP expect 262 cfm, at 0.100 in SP expect 212 cfm, and at 0.200 in SP expect 198 cfm.
