ebm-papst DiaForce 40mm Diagonal Compact DC Fans

ebm-papst DiaForce 40mm Diagonal Compact DC Fans offer an energy-efficient alternative to common counter-rotating fans, providing improved acoustic behavior, better tonality, and a simplified design. These mixed-flow fans combine the high airflow volume and standard installation footprint of an axial fan with the high back pressure capabilities of a centrifugal fan. This construction results in better air performance and lower noise. These ebm-papst DiaForce 40 series DC fans offer pulse width modulation (PWM) input for variable-speed control and dimensions of 40mm x 40mm x 56mm (H x W x D). The series is ideal for compact electronics, including routers, power supplies, robotics, and industrial automation systems.
