The FB3G133-2APL-70 is a 230VAC single-phase EC backward curved centrifugal fan designed for direct AC mains connection without external DC power supplies. Its BLEC72 motor delivers 467 m³/h (275 CFM) at 413 Pa while consuming only 48W at 4500 RPM—a direct drop-in upgrade from legacy AC shaded-pole and PSC fans with 30-50% energy savings. The 133mm form factor fits compact air handlers, fan coil units, and electronics cooling racks. Dual-frequency 50/60Hz compatibility ensures consistent performance across European and Asian installations. 0-10VDC/PWM speed control with FG tach feedback (3 pulse/rev) provides precision airflow regulation. CE, RoHS, ISO9001, ErP2026 certified with 50,000-hour L10 bearing life.
The FB3G133-2APL-70 features a BLEC72 permanent magnet brushless external rotor motor engineered for direct 230VAC single-phase operation at 50/60. The integrated AC-DC conversion eliminates the need for external power supplies, simplifying installation and reducing system cost. At 4500 RPM, the motor draws just 0.35A to produce 48W of shaft power, driving the 7-blade glass-fiber reinforced PP impeller to generate 467 m³/h at 413 Pa. The wide 184~270 VAC input handles grid voltage fluctuations. The die-cast aluminum housing provides IP44 protection and effective heat dissipation. Ball bearings support any-angle mounting with 50,000+ hour L10 service life at 40°C. Protection suite: soft-start, current limitation, under/over voltage, thermal overload, locked-rotor, reverse polarity. FG tach (3 pulse/rev). CE, RoHS, ISO9001, ErP2026 and EN ISO 12100, EN 60204-1, EMC compliant.

Remarks:
I. Standard cable length. The length of cable can be customized.
II. Conventional mode is 0-10V/PWM control. Modbus RTU over RS485 is available as an option.



Test condition:
I. The test data is obtained under the specified environment conditions and installation mode.
II. Input Voltage---Operating voltage.
III. Temperature---Room temperature 25°C.
IV. Humidity---65%RH.
I. When taking out the fan, do not directly lift the fan lead wire. If the lead wire is excessively stressed, the internal welding part may fall off
II. Do not plug or unplug the fan lead plug when the fan is running
III. If the fan does not work after starting, do not touch the impeller, rotor, or other parts, professional technical personnel are required to inspect the fan to prevent sudden start of the fan from causing hand or other personal injury
IV. Because of the soft start characteristics of the fan, to prevent personal injury, do not touch the impeller or other parts of the fan during powered on or running at low speeds
V. The fan needs to be operated and used under the guidance of professional personnel to prevent children from coming into touch this product
VI. If the power line is worn or damaged, it needs to be returned to the manufacturer for repair or be replaced under the guidance of the manufacturer
VII. As a part of the fan, it is not recommended to use the motor alone when there is no impeller or loading
1. 230VAC Plug-and-Play: The FB3G133-2APL-70 connects directly to standard 230VAC single-phase mains—no external DC power supply, no transformer, no additional wiring. 50/60 dual-frequency compatibility ensures seamless operation from European 50Hz grids to Asian mixed-frequency environments. The 184~270 VAC input tolerance handles real-world voltage fluctuations.
2. AC Fan Replacement: At 48W with EC motor efficiency, the FB3G133-2APL-70 directly replaces legacy 230VAC shaded-pole and PSC fans consuming 80-120W. Same wiring, same voltage, 40-60% lower energy cost. The 467 m³/h at 413 Pa matches or exceeds the performance of equivalent AC fans in a smaller, lighter package.
3. Precision Speed Control: 0-10VDC and PWM inputs enable stepless speed regulation from 0-4500 RPM. FG tachometer output (3 pulse/rev) provides real-time speed feedback for closed-loop control. The onboard controller includes soft-start, current limitation, thermal overload, locked-rotor, under/over voltage, and reverse polarity protection.
4. Compact & Certified: The 133mm form factor with die-cast aluminum housing and IP44 rating fits tight enclosures. Ball bearings rated for 50,000+ hours L10. CE, RoHS, ISO9001, ErP2026 with EN ISO 12100, EN 60204-1, and EMC compliance. -25°C to 60°C operating range.
5. OEM/ODM Flexibility: Custom voltage setpoints, connector types, cable lengths, and control interfaces available. Modbus RTU RS485 optional. 7-day standard samples, 14-21 day production. EXW, FOB, CIF, DAP, DDP terms available.
