Welcome to our FAQ page. We've compiled the most frequently asked questions regarding large industrial centrifugal fan procurement, technology, service, and logistics. If your question is not listed here, please feel free to contact our expert team.
1. Q: How many years of experience does your company have in this industry?
A: We have been specializing in the design, manufacturing, and sales of industrial centrifugal fans for over 10 years. We have long-term partnerships with leading manufacturers and extensive project experience in the power, metallurgy, chemical, building materials, and wastewater treatment sectors.
2. Q: What are your main products? Can you customize them?
A: Our product line includes various centrifugal fans, including forward-inclined and backward-inclined models, including high-pressure, medium-pressure, and low-pressure series. We can also provide special designs such as explosion-proof, corrosion-resistant, and high-temperature resistant, tailored to your specific operating conditions, air volume, air pressure, media, and space constraints.
3. Q: What international standards and certifications do your centrifugal fans comply with?
A: Our products strictly follow international standards such as ISO, CE, AMCA (Air Movement and Control Association), etc. We hold ISO 9001 quality management system certification, and some products have obtained CE certification, ensuring that their safety and performance meet the strict requirements of the international market.
4. Q: How do I select the right fan for my application?
A: Several key parameters are essential for correct selection:
● Required air volume
● System static pressure/total pressure
● Working medium and its characteristics (temperature, density, corrosiveness, dust load, etc.)
● Installation environment
We strongly recommend that you contact our technical team with your detailed requirements. We will provide you with accurate calculations and selection recommendations.
5. Q: Can you provide fan performance curves?
A: Of course. Each standard fan has a detailed performance curve. After you provide your basic parameters, we will provide you with the performance curve for the most suitable model to ensure that the fan operates within its high efficiency range.
6. Q: What is the primary material of the fan? What anti-corrosion treatments are provided?
A: Standard fans are primarily made of high-quality carbon steel. For special operating conditions, we offer a variety of material options, such as stainless steel, aluminum alloy, or the use of wear-resistant liners in critical areas. Anti-corrosion treatments include high-performance paint, hot-dip galvanizing, and epoxy coatings to withstand humid, acidic, and alkaline environments.
7. Q: What is the fan noise level?
A: Noise control is a key consideration in our design. We provide estimated sound pressure level data. If your project has strict noise requirements, we can provide noise reduction solutions such as silencers and soundproof enclosures.
8. Q: How do I get a quote?
A: You can submit your request through the [Inquiry Form] on our website or email us directly. Please provide as detailed technical specifications as possible so we can provide an accurate quote.
9. Q: How long is the quote valid?
A: Typically, our quotes are valid for 30 days. Due to raw material prices and market fluctuations, reconfirmation is required after the expiration date.
10. Q: What payment methods do you accept?
A: We support a variety of secure international payment methods, including:
* Wire Transfer
* Letter of Credit
* Other payment terms can be negotiated based on order value and previous cooperation history.
11. Q: What is the delivery time?
A: The delivery time for standard models is typically [4-8 weeks]. The delivery time for customized products varies depending on the complexity and will be clearly stated in the contract. For urgent orders, we can negotiate expedited production.
12. Q: Which countries do you ship to? How is logistics arranged?
A: Our products are exported to all over the world, including Europe, North America, Southeast Asia, the Middle East, Africa, etc. We have mature international logistics experience and can provide a variety of trade terms such as FOB, CIF, EXW, etc., and assist you with customs clearance documents.
13. Q: What is the product warranty period?
A: We provide a 12-24 month warranty on all our products, commencing from the date the equipment arrives at the destination port or upon commissioning (as determined by the contract). This warranty covers defects caused by raw materials and workmanship.
14. Q: Are installation, operation, and maintenance manuals provided?
A: Yes. Each wind turbine comes with a detailed English installation, operation, and maintenance manual containing drawings, parts lists, and step-by-step instructions. We also provide versions in other languages.
15. Q: Do you provide installation guidance or commissioning services?
A: We can provide professional installation guidance via remote video link. If required, we can also dispatch engineers to provide on-site installation supervision and commissioning services. The relevant fees are subject to separate negotiation.
16. Q: How do I order spare parts?
A: We guarantee a long-term supply of genuine spare parts. You can order through your dedicated account manager or directly contact our spare parts department. Please provide the wind turbine model and serial number so that we can quickly and accurately match you with a replacement.
17. Q: Can we provide drawings for you to manufacture?
A: Yes. We are happy to work with you on OEM/ODM projects. Our engineering team will review your drawings, assess their feasibility and optimization suggestions, and then provide you with a quote.
18. Q: For large projects, can you provide samples or conduct on-site testing?
A: For large centrifugal fans, providing complete unit samples is generally not practical due to their size and cost. However, we can arrange a factory visit for you to observe our manufacturing process and the testing of similar products. For key components, we can provide samples upon negotiation.
