Looking for a reliable high-static-pressure DC centrifugal blower for your thermal management project? The SZR-CAP150 (SZR15035) 24 V model stands out with 3800 RPM rated speed and a practical 4-wire setup integrating FG tachometer feedback and PWM speed control.
Built with UL94V-0 flame-retardant PPS plastic for both frame and backward-curved impeller, this Ø150 mm fan adopts ball-bearing construction, delivering up to 40000 hours service life. At 24 VDC nominal input, it produces maximum airflow of 3.83 m³/min (135 CFM) and 410 Pa static pressure, with noise kept at 59 dB-A, ideal for high-resistance ventilation scenarios.
The four-wire harness enables real-time speed adjustment via PWM input, while the FG signal feeds rotational status back to host controllers for system monitoring. Its wide storage temperature from -25 ℃ to +75 ℃ and optional IP ratings suit cabinets, chargers and industrial equipment. CE-certified, this compact blower balances performance, controllability and long-term durability for demanding DC cooling applications.
