FAQs
Do you offer volume discounts or customized solutions for large-scale procurement or OEM projects?
As a professional HVAC fan manufacturer, LONGWELL provides competitive tiered pricing for mid-to-large volume wholesale and OEM projects. For long-term B2B partners, we offer tailored support based on annual estimated quantities and specific application scenarios. Please reach out to the sales team directly to discuss specific commercial terms.Email:sales@longwellfans.com ,Tel:+0086 18358274663

Does the motor provide feedback for speed monitoring in our equipment?
Yes, all LWCE Series EC External Rotor Motors are equipped with a standard FG (Frequency Generator) Speed Feedback Signal. This allows your equipment to read the real-time RPM, enabling precise closed-loop control and fault detection-a critical feature for premium HVAC applications.

What EC Cross Flow Fan series are available for wholesale, and what lengths do you cover?
LONGWELL offers a comprehensive range to meet diverse HVAC integration needs, including series LWCE-80, LWCE-90, LWCE-100, and LWCE-150. Standard Stock Models: The LWCE-80 (350mm to 820mm) and LWCE-150 (380mm to 1200mm) series are detailed in our catalog for quick selection. Custom Sizing: For LWCE-90 and LWCE-100 series dimensions, or any intermediate lengths, please contact us for the specific datasheet. We specialize in accommodating OEM length requirements for bulk orders.

What is the default control signal? Is PWM customization available for our control board integration?
The standard factory configuration is 0-10V Analog Voltage input for smooth, linear speed control. Yes, PWM customization is available. If your system architecture requires a PWM (Pulse Width Modulation) signal, this is a popular modification for bulk OEM projects. Please specify “PWM Control Required” in your RFQ, or email us directly to ensure the correct firmware configuration before production.

Do you provide tiered pricing and technical support for large-volume OEM/ODM projects?
Absolutely. LONGWELL is a specialized manufacturer structured to support Mid-to-Large Scale Wholesale and OEM partnerships. We offer competitive tiered pricing based on Annual Estimated Usage (AEU). For long-term partners, we provide dedicated engineering support for custom housing, blade modifications, or specific wiring harnesses. Contact our sales team to discuss a tailored supply agreement.

How durable is the construction? What is the lifespan and operating environment rating?
Our EC Cross Flow Fans are built for commercial and industrial durability: Motor: High-efficiency EC External Rotor Motor. Housing: Rigid Steel + Aluminum Alloy construction. Impeller: Corrosion-resistant Aluminum Alloy blades. Bearing: Long-life Ball Bearing system. Safety: Insulation Class B. Environment: Reliable operation from -25°C to +60°C (-13°F to +140°F).

What is the difference between “Single” and “Double” blower models in the LWCE-150 Series?
This designation refers to the motor drive configuration, which is essential for performance stability: Single Blower: Standard single-motor drive. Recommended for lengths up to 700mm. Double Blower: Dual-Motor Synchronous Drive. This is required for longer models (e.g., 1000mm, 1200mm). It ensures balanced torque distribution, eliminates shaft wobble, and maintains quiet operation across the entire wheel width.

The datasheet shows 230V. Can you supply 115V or other voltages for the North American market?
Yes, we can support voltage customization for bulk orders. While our standard catalog lists 230V 50/60Hz, we understand the requirements for 115V or other specific voltages. This is managed as a Custom OEM Order. Please provide your target voltage and frequency; our team will evaluate the MOQ (Minimum Order Quantity) and lead time based on your required specifications.
