ANENG R3G310-H070 series is a drop-in EC centrifugal fan built for the 310 mm class — same footprint, same 0-10 V/PWM control language, with up to 2600 m³/h and 980 Pa, CE/ETL certified and available on a short lead time.
ebm-papst fans set a high bar for engineering quality, and the R3G310 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 R3G310 configurations against ANENG's 310 mm EC centrifugal models. Sizing is 1:1 in the 310 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.
Both ANENG models accept standard 0-10 V DC and PWM speed-control signals, so they drop into most BMS and controller setups that drive an R3G310-class EC fan. Confirm your existing control scheme (analogue loop, PWM frequency and any Modbus expectations) with our engineers — we will confirm the interface details before you commit.
ANENG 310 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 310 mm footprint and control interface match, and where the duty point sits inside the ANENG performance envelope (up to 2,600 m³/h and 980 Pa for the -02B). Verify mounting dimensions and operating point with our engineering team and a sample before full adoption — that is the reliable way to qualify any alternative source.
Both models support standard 0-10 V DC and PWM speed control, which covers the common analogue control language used with R3G310-class EC fans. Confirm PWM frequency and any additional bus requirements with us before ordering.
We do not publish a blanket "fits every R3G310" claim. Instead 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.
The 310 mm EC centrifugal range 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.
