Design and Performance
Concentrated Airflow via Centrifugal Force
Centrifugal fans and blowers move air by means of the centrifugal force generated by rotating a cylindrical runner fitted with blades, concentrating airflow through a small outlet in a single defined direction — ideal for targeted local cooling.
High Static Pressure for Restrictive Airflow Paths
This design creates large static pressure, making the MB840-B optimal for cooling equipment through which air cannot flow easily, as well as for pushing air through ducts where axial fans would struggle to maintain flow.
Compact 80mm Frame for Small-Scale Local Cooling
An 80mm impeller diameter keeps the blower’s footprint compact, suited for targeted cooling of small components, tight enclosures, or localized hot spots within larger equipment assemblies.
Flexible Fixed or Moving-Part Mounting
The MB840-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.
Compatible with Filter and Mounting Bracket Kits
Pairs with dedicated filter and mounting bracket accessory kits (available as complete kits), supporting filtered airflow and secure installation in a single coordinated package.
