Design and Performance
Concentrated Airflow for Directional Cooling
Unlike axial fans, this centrifugal fan/blower maximizes static pressure to provide concentrated airflow in one defined direction, making it well suited for local cooling and airflow through ducts where directed air pressure matters more than broad volume.
Flexible Fixed or Moving-Part Mounting
The MB1255-B can be used in a fixed position or mounted on moving parts, giving engineers flexibility to integrate it into both stationary control panels and machinery with moving components requiring localized cooling.
Reliable Single-Phase Power Compatibility
Rated for 100/110/115 VAC single-phase supply, this blower suits control panel and equipment cooling applications across a wide input voltage range (90–126 VAC) without requiring specialized power infrastructure.
Genuine Fit for Existing MB Series Installations
As a documented Oriental Motor part number, the MB1255-B ensures correct fit, airflow performance, and mounting compatibility when used as a replacement in existing MB Series centrifugal fan installations.
Compatible with Filter and Mounting Bracket Accessories
Pairs with the FLB12 filter and PAS6A mounting bracket (available as a complete kit) to support filtered airflow and secure installation in a single coordinated package.
