ANENG R3G280-H086-02B is a drop-in EC centrifugal fan built for the 280 mm class — 230 VAC, up to 2520 m³/h and 620 Pa static pressure, 0-10 V/PWM control, NMB ball bearing, CE certified and short lead time.
ebm-papst fans set a high bar for engineering quality, and the R3G280 is a workhorse in precision-air and clean-environment equipment. OEMs and maintenance teams still look for a qualified second source for three practical reasons:
The table below compares the common ebm-papst R3G280 configuration against ANENG's 280 mm EC centrifugal model. Sizing is 1:1 in the 280 mm class — always confirm bolt-hole circle, shaft height, orientation and control signal against your installation before ordering (dimension drawings are available on request).

Performance values are at the fan's typical rated conditions. Compare at your actual system operating point, not only at nameplate maximums.
The ANENG model accepts standard 0-10 V DC and PWM speed-control signals, so it drops into most BMS and controller setups that drive an R3G280-class EC fan. Confirm your existing control scheme (analogue loop, PWM frequency and any Modbus expectations) with our engineers before you commit.
ANENG's 280 mm EC centrifugal fans are CE/ETL certified, use NMB ball bearings for long, stable life, and are available for OEM customisation (voltage, terminations, coatings). Factory QC and traceability are maintained in-house in Shanghai.
It can where the 280 mm footprint and control interface match, and where the duty point sits inside the ANENG envelope (up to 2520 m³/h and 620 Pa). Verify mounting and operating point with our engineers and a sample.
Both models support standard 0-10 V DC and PWM speed control, which covers the common analogue control language used with R3G280-class EC fans. Confirm PWM frequency and any additional bus requirements with us before ordering.
We supply the specific dimension drawing for your chosen model so you can compare against your installation plate, and offer production samples for physical validation. Fit is confirmed per-installation, not assumed.
This 280 mm EC centrifugal model is CE/ETL certified. OEM-build options for voltage, terminations and coatings are available. Request current certificate PDFs for your target model.
Because ANENG manufactures in-house, standard models can ship significantly faster than typical overseas import lead times. Contact us with your volume and program timing for a firm schedule.
Send us your mounting drawing and your airflow / static-pressure operating point. Our engineers will confirm the matching model and PQ curve — no obligation.
