W40S12BHA5-07 Nidec 12VDC 0.17A 40x40x28mm Axial Fan

Description

The Nidec W40S12BHA5-07 is a high-performance DC brushless axial fan from the UltraFlo series, engineered for high-density thermal management. This 4028-size unit utilizes a dual ball bearing system to ensure a long service life of up to 70,000 hours at 40°C. Operating at a nominal 12VDC with a low current draw of 0.17A, it delivers a balanced 15.0 CFM airflow and 0.58 inH2O static pressure. The fan features a robust PBT plastic housing and impeller (UL94V-0 rated) designed to maintain structural integrity in demanding industrial environments while providing efficient cooling for space-constrained enclosures.
