Key features

180mm Diameter: 180mm DC impeller for ventilation, cooling, and heating duct runs sized to match standard duct cutouts of the same dimension.

BLDC Motor: Brushless DC motor runs on 12V or 24V DC input so the fan draws steady current instead of a start-up surge.

Galvanized Construction: Blade and housing in galvanized metal for durability and corrosion resistance.

Speed Control: Accepts 0-10V or PWM signal for stepless airflow adjustment letting your controller hold a steady point instead of a fixed step.

Broad Applications: Fits HVAC, server cooling, telecom, floor heating, and cooling systems.

OEM ODM Customization: Full customization including voltage, housing material, and branding.

Quality Assurance: 100% finished product inspection with traceable raw materials before the unit ever reaches your line.

AI-Powered supplier vetting

SummaryThe supplier is a China-based HVACR manufacturer offering OEM/ODM services, product customization, and stated 24/7 after-sales support. It reports annual production capacity for cross-flow, centrifugal, and axial fans, supported by cutting, laser-cutting, bending, rolling, and punching equipment. The supplier holds product, management-system, and social-responsibility certifications, and reports overseas service resources including an overseas warehouse, showroom, agents or branches, and participation in the Climate World trade show. Evidence of innovation is positive through recent new-product development and ODM services. Customer references are also favorable, including cooperation with Fortune 500 companies and an 80%–100% repeat-buyer preference. However, service-management procedures lack supporting records, and no approved supplier list is maintained. Financial information is insufficient to assess credibility because the slices provide only reporting years, not financial performance values.

Supplier typeThe supplier operates from Zhejiang, China, and its stated business scope covers manufacturing and processing of hardware tools, electronic components, plastic products, and mechanical and electrical equipment, along with technology R&D, design, and sales. Its company overview specifically positions it as an HVACR OEM/ODM solution provider.

CertificationsThe supplier reports FCC, CE, RoHS, and other product certifications, ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, plus BSCI social-responsibility certification. These certifications provide explicit evidence of compliance and management-system coverage.

After-Sales capabilityThe supplier states that it provides 24/7 after-sales service and offers overseas debugging, maintenance, repair, training, and equipment installation in Russia. It also reports an overseas warehouse, showroom, agents or branches, and trade-show participation; however, the slices do not verify service performance outcomes.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and lists technology research and development, technical consulting, technology transfer, and design within its business scope. It does not provide an SDK, but that limitation is not sufficient to negate the broader evidence of product and technical R&D capability.

Production capacityReported annual productivity is 200,000 cross-flow fans, 300,000 centrifugal fans, and 200,000 axial fans. The supplier also lists cutting, laser-cutting, bending, rolling-and-bending, and punching equipment, supporting a demonstrated manufacturing base.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These services are reported both as an R&D/design capability and as a general design-services capability.

Client casesThe supplier reports providing OEM services for well-known brands and having cooperated with Fortune 500 companies. It also reports an 80%–100% repeat-buyer preference, although no customer names, project details, or independently verifiable case records are provided.
