FOCUS ON EC FAN ONLY
PBM FOCUS ON EC FAN ONLY. Certificate: CE,UL,ROHS; Supply Ability: 100,000 pcs per year; MOQ: 1~100 pcs based on EXW price; 100 pcs above based on FOB price.
The PB3N190B24-TZ0 is a high-performance variant within PBM's 190mm DC IP55 platform. The PB3N designation represents PBM's 3rd-generation backward curved centrifugal fan platform, with 190 indicating a 190mm impeller diameter, B for ball bearings, 24 for 24V DC rated voltage, and TZ0 as the IP55 waterproof and dustproof specification identifier.
Compared to the RZ0 version (3,500 RPM, 710 m³/h, 840 Pa, 68 dB(A)), the TZ0 version delivers significantly enhanced performance with higher speed (4,050 RPM) and greater airflow output (820 m³/h) , making it particularly suitable for demanding applications requiring high static pressure and high airflow, such as cleanroom FFU systems and medical rehabilitation equipment.
With low touch current risk, this backward curved centrifugal fan can be powered directly from equipment DC buses or SELV (Safety Extra-Low Voltage) power supplies — making it especially well-suited for medical rehabilitation equipment and cleanroom devices with stringent electrical safety requirements.
PBM is more than just a fan manufacturer — we are your total solution provider for medical rehabilitation equipment and industrial ventilation and thermal management systems.
Choose the PB3N190B24-TZ0 for a high static pressure, low noise, IP55 EC-DC backward curved centrifugal fan for your most demanding cleanroom and medical applications.
