Based on the keywords you provided, it appears you are looking for information or a supplier for a 6-12 series customized centrifugal blower fan that is high-temperature resistant and has a CE certificate.

Here is a breakdown of what this typically means, along with guidance on specifications, customization, and sourcing.

What is a "6-12 Series" Centrifugal Blower?

The "6-12" likely refers to a specific model designation used by a manufacturer. In centrifugal fan nomenclature, this often refers to:

• Type: A backward-curved or forward-curved centrifugal fan. (Most common in industrial high-temp applications).
• Series: A specific product line that defines the impeller diameter, housing size, and performance curve.
• Numbering: Often, the "6" refers to the impeller diameter (e.g., 6 inches or 600mm) and "12" might refer to the housing width, motor frame size, or blade count.

Key Features You Mentioned

1. Customized

   • Motor: Custom kW, RPM, voltage (e.g., 3-phase 380V/50Hz or 415V).
   • Material: High-temperature steel (e.g., 304/316 Stainless Steel for higher corrosion resistance).
   • Inlet/Outlet: Custom flanges, angles, or duct connections.
   • Coating: High-temp paint or powder coating.

2. High Temperature Resistant

   • This is the most critical specification. "High-temperature resistant" usually means the fan can handle air/gas temperatures from 200°C up to 800°C (392°F to 1472°F).
   • Key design differences for high temp:
     • Bearing cooling: The motor bearings are often located outside the airstream (belt-driven) or have cooling fins/fans.
     • Shaft seal: High-temp labyrinth seals or carbon seals prevent hot air from reaching the motor.
     • Materials: Impeller and housing made from corten steel or stainless steel to handle thermal expansion and corrosion.

3. CE Certificate

   • EU Compliance: The CE mark is mandatory for sale in the European Economic Area (EEA).
   • What it covers: Safety, health, and environmental protection standards (Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, EMC Directive 2014/30/EU).
   • Verification: Ask to see the Declaration of Conformity (DoC) and the Technical File. A legitimate CE mark means the manufacturer has performed a risk assessment and the fan meets harmonized standards.

Sourcing & Suppliers

You would typically find these from:

• Industrial fan manufacturers in China (e.g., from Shandong, Zhejiang, or Jiangsu provinces).
• Specialized OEMs (Original Equipment Manufacturers) for kilns, ovens, dryers, or pollution control.
• Global brands with local distributors (e.g., Soler & Palau, Greenheck, Systemair - but these are usually not "customized" to the same degree as Chinese OEMs).

Where to look:

• Alibaba / Made-in-China: Search for "High temp centrifugal fan 6-12 series CE." Be prepared to filter by supplier verification (gold supplier, trade assurance).
• Industry Trade Shows: (e.g., Canton Fair, Hannover Messe).
• Direct from Manufacturer: Search for "CE centrifugal blower manufacturer" + "custom high temperature."

Important Questions to Ask a Supplier (If Requesting a Quote)

1. Model Confirmation: "Please confirm the exact meaning of the 6-12 series. Is it 6 inch or 600mm impeller?"
2. Temperature Rating: "What is the maximum continuous operating temperature? (e.g., 250°C, 400°C, 600°C)?"
3. Motor Type: "Is the motor directly coupled or belt-driven? Are the bearings high-temp rated and located outside the airstream?"
4. Material: "What is the impeller material? (e.g., Q235 (mild steel), Q345R (corten), SS304, SS316)?"
5. CE Documentation: "Can you provide the CE Declaration of Conformity (DoC) and the test report for the specific model?"
6. Customization Details:
   • "What are the custom inlet/outlet dimensions?"
   • "We need a specific motor power of 2.2kW, 4-pole, 3-phase, 380V. Can you supply this?"
   • "Is a thermal insulation jacket required for the housing?"

Summary for Your Needs

• Product: 6-12 Series Centrifugal Blower Fan
• Key Requirements: Customized, High Temp Resistant (>200°C recommended), CE Certified.
• Action: Contact a reputable OEM supplier on Alibaba or a specialized industrial fan manufacturer. Provide them with your specific airflow (m³/h or CFM), static pressure (Pa or in. WG), gas temperature, and ambient conditions.
• Red Flag: If a supplier says "high temp" but cannot explain how the bearings are cooled, proceed with caution. True high-temp fans use belt drive with external bearings or water-cooled bearings.
