The Lobisong LBAA2D200S-7MKW-10 is a dual-voltage 200mm AC axial fan engineered for global OEM export. This dual voltage axial fan accepts either 380V or 400V three-phase 60Hz mains, spinning a Ø200mm cold-rolled impeller at 2,400 rpm to deliver 1,009 m³/h. Instead of stocking separate SKUs for 380V and 400V destination markets, export equipment manufacturers specify this single dual voltage axial fan and let the motor absorb both grids — simplifying BOMs, spares and global service. One dual voltage axial fan, many destination countries: that is the export OEM promise.

Global OEM shipping is a SKU problem. A machine built in Suzhou for a customer in Jeddah runs on 380V 60Hz; the same machine sold to a customer in Jakarta may land on 400V 60Hz. Stocking two near-identical fans doubles inventory, doubles picking errors and doubles after-sales complexity. This dual voltage axial fan resolves the split: the winding is designed to accept either 380V or 400V three-phase 60Hz directly, with no field reconnection, no tap selector and no transformer. The dual voltage axial fan draws 0.13 A at 70 W in either mode and holds 2,400 rpm and 1,009 m³/h across the input range.

The engineering behind the dual rating is winding tolerance. A 380V motor built to a 342–418V window already covers 400V; what usually stops manufacturers from advertising that range is magnet wire insulation margin and saturation flux. By winding with Class F (155°C) magnet wire and designing the magnetic circuit below saturation at 418V, the same dual voltage axial fan runs correctly on both nominals without overheating. IP44 sealing, S1 continuous-duty bearings and a -30°C to +60°C ambient window round out a dual voltage axial fan built for global field conditions — from Middle-East summer heat to Southeast Asian humidity.

• Dual 380V/400V 60Hz rating: One SKU covers two nominals across export markets, cutting BOM and spares.
• 1,009 m³/h at 2,400 rpm: Same class-leading airflow as the IP54 200mm variant, from a 70 W motor.
• Cold-rolled steel impeller: Ø200mm blade holds its aerodynamic profile through years of sustained 2,400 rpm.
• 0.13 A low current draw: Light branch loading in export equipment where feed capacity is budgeted.
• IP44 splash protection: Dust- and splash-resistant for factory floors, humid cabinets and sheltered outdoor use.
• S1 continuous-duty bearings: Maintenance-free ball bearings rated for 24/7 export-equipment duty cycles.

The export-equipment fan problem is not just about voltage — it is about configurability. A machine builder selling to 20 countries does not want to branch the BOM on nominal grid voltage. They want one fan that works in every destination. This 60Hz axial fan delivers that through winding headroom: the 342–418V window absorbs both 380V and 400V nominals, so the same dual voltage axial fan ships in a container to Riyadh, Karachi and Ho Chi Minh City without a wiring change. The 60Hz specification then excludes 50Hz European grids on purpose, avoiding the over-speed risk that mis-application creates for a dual voltage axial fan.

Why IP44 rather than IP54? Because export equipment often ships inside enclosed machinery, not in the open. The dual-voltage model targets OEM cabinets, process skids and packaged units where dust and splash exposure is moderate. IP44 sealing blocks solid objects above 1 mm and water splash from any direction — enough for most indoor and sheltered outdoor locations, without the extra housing cost and 5 dB(A) noise penalty of a fully sealed IP54 build. The 60 dB(A) figure reflects that open-frame-style airflow path, which suits equipment where ambient machinery noise already dominates, and which keeps the dual voltage axial fan affordable for export.

• Export OEM equipment cooling: One fan SKU on machines shipping to 380V and 400V 60Hz destination markets.
• Multi-country project standardization: Specify a single part number across Southeast Asia, the Middle East and Africa.
• Marine and offshore platforms: Dual-voltage 60Hz ventilation for shipboard machinery and auxiliary spaces.
• Process equipment and welding stations: Continuous S1 duty preventing thermal derating of VFDs and inverters.
• Agricultural and food-processing ventilation: 1,009 m³/h for grain dryers and packaging lines in humid climates.

For export OEMs, this dual voltage axial fan pays back in inventory math. Consolidating two near-identical SKUs into one cuts line-side bin count, reduces picking errors and simplifies after-sales stocking by geography. The 70 W draw and 0.13 A current keep the dual voltage axial fan easy to integrate; the -30°C to +60°C window handles destination climates from Gulf heat to highland cold; and the IP44 rating is adequate for the enclosed machinery where most export fans actually live. Standardizing on one dual voltage axial fan across export regions is the single highest-leverage B2B decision an OEM can make on ventilation.

Q:Does this fan auto-switch between 380V and 400V, or do I rewire it?

A:You do nothing. The motor accepts either 380V or 400V three-phase 60Hz directly. Connect your local supply; it runs at 2,400 rpm and 1,009 m³/h across the dual-rated range without taps or jumpers.

Q:Why is this dual-voltage fan rated 60 dB(A) when the IP54 200mm variant is 55?

A:The 5 dB(A) gap reflects housing and seal construction. Both deliver 1,009 m³/h. Choose the IP54 variant if you need dust-tight sealing and quieter operation; choose this dual-voltage model when global grid compatibility matters more.

Q:Can this fan be used on 50Hz European grids?

A:It is wound for 60Hz. On 50Hz it under-speeds and loses torque. For 50Hz EU markets, specify our 50Hz SKU; this dual-voltage 380/400V 60Hz model is built for export to 60Hz regions.
