750mm Oscillating Industrial Wall Fan for UK Warehouses Case Study

Customer Requirement

A 220V power supply was the primary electrical constraint for a UK-based systems integrator seeking a general-purpose industrial air circulator. The project brief, logged under LWIF-750U(S)-02, specified a 750mm (30-inch) wall-mounted axial fan. The end application was clearly for personnel comfort and air movement in a large commercial or light industrial space, such as a warehouse, assembly floor, or workshop. The client’s requirements were direct and focused on quality and regional compliance. They mandated a factory-fitted British Standard plug, eliminating the need for post-delivery modification.

Material specifications were explicit. The request for “aluminum blades” and a “copper wire” motor indicated a procurement manager familiar with fan construction, prioritizing long-term durability and performance over lower-cost alternatives. The fan needed an integrated oscillating function, controllable via a simple switch, to distribute air across a wide area. Additional requirements included adjustable 3-speed operation and a robust wire guard for safety compliance under standards like EN 60335-1. The customer provided a reference image of a generic industrial wall fan and required a formal Longwell specification sheet and drawing to finalize their purchase order. The request was tagged ‘下单用’ (for ordering), signaling high commercial intent and the need for a rapid, accurate response from our engineering team.

Engineering Solution

Upon receiving the project input, the engineering team immediately classified the request as a standard product fulfillment. The specified parameters—a 750mm axial fan, 220V AC power, oscillation, and specific materials—are core to our industrial fan portfolio. The initial engineering question was whether any customization was needed. We cross-referenced the customer’s list of requirements against our LWIF (Longwell Industrial Fan) series.

The standard Longwell model LWIF-750S-09 was identified as a direct, 100% match. This negated the need for a new product introduction (NPI) cycle. An alternative using an EC motor was briefly considered. An EC fan would offer higher efficiency and smart control capabilities via our SmartEC™ platform. However, the customer’s request for simple 3-speed adjustment and one-touch oscillation suggested a primary focus on cost-effective, reliable air circulation without complex BMS integration. Proposing an EC solution would have been an over-specification, adding unnecessary cost and complexity for the stated application. Therefore, the robust AC motor with pure copper windings was the correct and most economical solution, aligning perfectly with the client’s focus on fundamental quality.

The request for aluminum blades was also met by the standard model, which uses a 3-blade aluminum design balanced for high air volume and durability. The final engineering action was to pull the existing, approved technical documentation for the LWIF-750S-09, confirm that our production line could fit a British plug, and release the files to the sales team. The entire process from ‘Sales Input’ to the delivery of the LWIF-750S-09.pdf specification sheet was completed in under two working days.

Technical Specifications

The 17,400 m³/h air volume delivered by the 260W motor establishes this fan as a highly effective solution for circulating air in large-volume spaces, ensuring temperature equalization and improved worker comfort with minimal energy expenditure.

Technical Documentation

Why Longwell for This Application

• Rapid Fulfillment of Standard Orders: This project demonstrated Longwell’s ability to move from a customer inquiry to providing order-ready documentation within days. For standard catalog items like this industrial fan, our 15-25 day Make-to-Order (MTO) lead time for batch production is significantly faster than the typical 12-18 week lead times from many European suppliers.
• Assured Compliance and Quality: The fan is CE marked, meeting European LVD and EMC directives. It’s built in our ISO 9001/14001/45001 certified facility, with a 100% copper winding motor and fused protection as standard. This provides auditable proof of quality and safety, a critical factor for procurement managers. The ability to supply a factory-fitted British plug further reduced project friction and cost for the customer.
• Industrial Grade at a Commercial Price Point: By matching an existing, high-volume model to the customer’s need, Longwell provided a solution with industrial-grade reliability at a price point estimated to be 35-38% lower than a comparable European-branded fan. This delivers a superior total cost of ownership, especially valuable for large-scale facility fit-outs.
• Extensive Portfolio for Future Needs: While this project required a simple AC fan, the successful and swift fulfillment builds a foundation for future business. Should the customer require fans for hazardous locations (ATEX), high-pressure ventilation (centrifugal blowers), or energy-efficient smart systems (EC fans), Longwell offers a compatible series, positioning us as a long-term, single-source ventilation partner.

Frequently Asked Questions

Q: What is the typical lead time for an order of 50 LWIF-750U(S)-02 fans to the UK?

A: For an order of 50 units, the standard Make-to-Order (MTO) manufacturing lead time is 15-25 business days. When combined with ocean freight and customs clearance, the typical door-to-door delivery time to a UK site is approximately 45 to 65 days from the date the purchase order is confirmed.

Q: Is the LWIF-750U(S)-02 suitable for outdoor use or in a dusty workshop?

A: The standard fan is designed for indoor or covered outdoor use and is not fully waterproof. It performs exceptionally well in dusty environments like woodworking shops or warehouses due to its robust motor and guarded design. For applications requiring specific dust or gas protection, such as ATEX-rated zones, we would specify a different fan series. Our REM series, for example, offers ATEX Zone 22 certification for combustible dust environments.

Q: The spec sheet shows 220V, but the UK standard is 230-240V. Is this compatible?

A: Yes, the fan is fully compatible. The motor and electrical components are engineered for a 220-240V / 50Hz operational window, which covers the electrical standards across the UK and Europe. The fan will deliver its nameplate performance of 17,400 m³/h airflow throughout this entire voltage range without issue.
