The Lobisong LBAA2D200S-7MEB-06 is a high-airflow 200mm AC axial fan built for large-volume air exchange on 60Hz three-phase grids. This industrial axial fan unit is driven by a 380V three-phase motor, spinning a Ø200mm cold-rolled impeller at 2,400 rpm to deliver 1,009 m³/h — nearly double the output of quieter 200mm alternatives. IP54 sealing, Class F insulation and a -30°C to +60°C window make this industrial axial fan unit the workhorse for warehouses, workshops and equipment rooms where stale, hot air must be moved quickly. When the brief is volume, this industrial axial fan unit is the answer.

Big spaces move big volumes. A warehouse, workshop or sports hall accumulates heat, fumes and stale air across thousands of cubic meters; a single small fan will not dent that load. This industrial axial fan unit addresses the problem at the source: 1,009 m³/h from a single Ø200mm unit, so one industrial axial fan unit replaces two or three smaller ones and cuts installation cost, mounting brackets and electrical feeds. The 380V three-phase 60Hz motor is wound for North American and Asian-Pacific grids where 60Hz mains are standard, delivering full torque and correct speed from this industrial axial fan unit without the over-speed or under-torque problems that arise when a 50Hz motor is misapplied.

IP54 is the enabler. Large-space ventilation rarely happens in a clean office: warehouses have dust, workshops have grindings, loading docks have condensation. An IP20 open-frame fan would clog and corrode; this 60Hz three-phase fan is dust-protected and splash-sealed, so daily plant conditions do not degrade the industrial axial fan unit. The 70 W draw is remarkably low for 1,009 m³/h — the aerodynamic disc area of the 200mm impeller does the heavy lifting, so the industrial axial fan unit only overcomes the small static resistance of open grilles and short duct runs. Sealed ball bearings run S1 continuous duty and carry a 30,000-hour L10 rating, so the industrial axial fan unit stays on line for years.

• 1,009 m³/h class-leading airflow: One 200mm unit replaces two smaller fans, cutting mounts, wiring and controls.

• 380V three-phase 60Hz winding: Correct speed and torque on 60Hz grids across North America, Southeast Asia and the Middle East.

• 342–418V input tolerance: Absorbs brown-outs, long cable runs and utility fluctuation without stalling.

• IP54 dust and splash sealing: Survives warehouse dust, workshop grindings and dock-side condensation.

• 70 W high-efficiency output: 1,009 m³/h from 70 W means low energy cost per cubic meter moved.

• S1 continuous-duty bearings: Maintenance-free ball bearings, G6.3 balance (JB/T8686), 30,000 h L10 life.

Axial fan performance follows a simple geometric rule: airflow scales with impeller disc area times tip speed. The 200mm disc gives roughly 15% more swept area than 185mm; combined with the 2,400 rpm tip speed, that is how this 60Hz three-phase fan reaches 1,009 m³/h. But axial fans trade static pressure for volume, so the honest application note is to keep the resistance path short — open grilles, short ducts, uncluttered filter banks. Pushed against a heavily loaded filter or a long silencer, airflow falls off sharply. Specify this industrial axial fan unit where the air path is free and the volume is large.

Three-phase 60Hz operation is a regional fit, not a compromise. A 50Hz motor connected to 60Hz mains over-speeds by 20%, risking bearing and winding stress; a 60Hz motor on 50Hz under-speeds and loses torque. Wound correctly, this 380V 60Hz industrial axial fan unit hits its design point on first switch-on, with no capacitor, no start relay and no thermal surprises. The 342–418V window absorbs the voltage sag that happens when a warehouse compressor or a press line starts on the same feeder, which is a daily reality in large industrial spaces where this industrial axial fan unit earns its keep.

• IP54 warehouse ventilation: 1,009 m³/h exchange for racking aisles and mezzanines where heat rises.

• Factory workshop make-up air: Fume dilution and temperature control in production floors.

• Gymnasiums and exhibition halls: Large-space air turnover for sports facilities and convention floors.

• Data center and telecom cooling: High-volume rejection of IT heat in hot-aisle containment loops.

• Loading-dock and dock-house ventilation: IP54 operation in splash-prone, dusty bays.

For EPC contractors and warehouse operators, this high airflow industrial fan compresses cost per cubic meter. One 200mm industrial axial fan unit replaces two or three smaller fans, halving mounting brackets, electrical feeds and BMS points. The 70 W draw keeps high-airflow fan ROI per 1,000 m³/h, and the IP54 build avoids the early-failure mode that plagues open-frame fans in dusty bays. Specifying a single 60Hz industrial axial fan unit across a multi-warehouse roll-out also simplifies spares and maintenance training, so one crew knows one product.

Q1: Why is this fan louder than the single-phase 1370 rpm 200mm model?

A: It runs at 2,400 rpm on three-phase torque to deliver 1,009 m³/h — nearly double the airflow. The 55 dB(A) output is the acoustic trade-off. Choose the 1,370 rpm single-phase variant if quiet comfort beats peak volume.

Q2: Can this 380V 60Hz fan run on 50Hz mains?

A: It is wound for 60Hz. On 50Hz it under-speeds and loses torque. For 50Hz markets, specify Lobisong AC fan supplier; for 60Hz North American, Asian-Pacific and Middle-East grids, this is the correct part.

Q3: What static resistance can this 1,009 m³/h fan push against?

A: It is optimized for low-resistance paths — open grilles, short ducts and clean filter banks. Push it against a heavily loaded filter or a long silencer, and airflow falls off sharply. For high-static ducted systems, spec a centrifugal blower instead.
