3252J/2H3P

The 3250J series high-performance Compact Fan is ideal for dissipating heat in limited space environments with lower system resistances. The fans run at very high speeds to maintain performance against high system resistance. It extends this application range with fans designed specifically for lower system resistances, therefore operating at more moderate speeds. In addition, the impeller has added aero acoustic improvements including an artificially generated surface disturbance on the blades which acts as a tabulator delaying an impending stall. These changes result in a substantial lowering of acoustic noise.
