EBM-Papst S-Force tubeaxial fans can achieve operating values previously attained only by the use of large axial fans. Devices are available in 5 series, ranging in sizes of 80mm to 172mm. Each series represents the benchmark of its class with respect to air performance and pressure build-up, optimum motor efficiency and long service life. The 80mm for example, running at free air can move up to 130CFM of air, while the 172mm is able to move an impressive 559CFM. Products provide integrated wear-free commutation electronics, multiple fixed-link struts to enable nominal speeds of up to 14,000 rpm and speed-dependent self-ventilation of the motor to ensure fan life values of 70,000 hours or more.
