The W9-28 high temperature centrifugal fan is designed for industrial hot-gas handling where high efficiency, low noise, stable performance and a wide airflow adjustment range are required.
The series is intended for non-corrosive, non-self-igniting hot gases. According to the original product documentation, the series temperature limit is up to 550°C and the conveyed medium should contain less than 150 mg/m³ of dust.

Where the W9-28 High Temperature Fan Fits
W9-28 is intended for industrial systems that must continuously move hot process gas while maintaining useful centrifugal-fan pressure capability. Typical project directions include furnace exhaust, kiln ventilation, thermal processing equipment, hot-air circulation and other non-corrosive high-temperature exhaust duties.
It forms part of QIYUE FAN's broader Boiler & High Temperature Fans product family.
Furnace Hot-Gas Exhaust
Extraction of non-corrosive hot gas from industrial furnaces and thermal-processing equipment.
Kiln & Thermal Process Ventilation
High-temperature ventilation where airflow and pressure must be maintained through a ducted system.
Industrial Hot-Air Systems
Process-air duties requiring a centrifugal fan designed around elevated operating temperatures.
Engineered Replacement
Replacement of an existing hot-gas fan where duty point, temperature, interfaces and foundation data can be confirmed.
550°C Is a Series Limit, Not a Universal Operating Point
The original W9-28 series description states that conveyed-gas temperature should not exceed 550°C. However, the published performance data show different working temperatures for different fan sizes and mechanical arrangements.
This distinction is important because gas temperature changes density, fan pressure, absorbed power and the mechanical requirements of the fan. For the underlying selection logic, see How Gas Temperature Affects Industrial Fan Performance .
One W9-28 Series, Multiple Drive Arrangements
W9-28 is not one mechanical design scaled through every size. The original catalogue includes C-, D- and F-type configurations depending on fan size and duty. Motor location, bearing arrangement, foundation layout and overall dimensions therefore vary across the series.
C-Type Arrangement
Published on the smaller No.5 configuration. Mechanical layout differs from the larger D- and F-type fans.
D-Type Arrangement
Used across several medium W9-28 sizes including No.7.6, No.9, No.11.2, No.14, No.15 and No.16 configurations.
F-Type Arrangement
Used for larger published configurations including No.16F, No.17F and No.22F.
W9-28 Series Performance Envelope
The table below summarizes the published duty ranges so buyers can determine whether W9-28 is a realistic candidate before detailed selection. Each final operating point must still be checked against the corresponding performance data.
Read Airflow, Pressure, Temperature and Speed Together
A W9-28 model cannot be selected from airflow alone. Airflow and total pressure define the aerodynamic duty, while temperature changes the gas density and required power. Rotational speed and mechanical arrangement must then be checked against the selected configuration.
Buyers unfamiliar with industrial fan charts can first review How to Read a Fan Performance Curve .
Define Airflow
Specify required operating airflow in m³/h.
Define Pressure
Confirm system resistance and required total or static pressure.
Confirm Temperature
Provide continuous and maximum hot-gas temperature.
Check Medium
Gas composition and dust loading must remain compatible with the fan configuration.
Select Configuration
Confirm size, speed, C/D/F arrangement, motor and installation interface.
W9-28 No.9D Outline & Installation Dimensions
The drawing below shows one representative No.9D arrangement, including the fan casing, bearing housing, motor position, foundation reference and available outlet orientations.
What Changes in a High-Temperature Fan Project
High-temperature fan selection is not only an aerodynamic calculation. Thermal expansion, bearing environment, gas composition, dust loading, motor arrangement and installation interfaces must also be considered before production.
Continuous vs Peak Temperature
Both normal operating temperature and short-duration maximum temperature should be provided.
Gas Composition
A high temperature rating does not automatically make the fan suitable for corrosive or reactive process gases.
Dust Loading
Original series documentation specifies dust content below 150 mg/m³. Higher or abrasive loading requires separate evaluation.
Bearing & Cooling Arrangement
Bearing environment and cooling details depend on fan size, temperature and selected mechanical configuration.
Rotation & Outlet Position
Available outlet directions vary by configuration. Rotation and discharge orientation should be confirmed from the project duct layout.
Motor & Power Supply
Motor power, voltage, frequency and starting method are confirmed according to the selected operating point and destination market.
What to Send for W9-28 Selection
A useful W9-28 quotation starts with the operating condition. Sending only a fan model or motor power is normally not enough to verify performance.

W9-28 High Temperature Centrifugal Fan FAQ
Can every W9-28 fan operate continuously at 550°C?
No. The original series description gives a maximum medium-temperature boundary of 550°C, while individual published configurations have different working temperatures. Final suitability must be checked against the selected size and actual duty.
What type of gas can the W9-28 handle?
The series is intended for non-corrosive and non-self-igniting high-temperature gas. Other chemical or hazardous media require separate material and safety evaluation.
What is the published dust concentration limit?
The original W9-28 series description specifies dust content below 150 mg/m³.
Why does the W9-28 series use C, D and F drive arrangements?
Different fan sizes and duties use different mechanical layouts. The selected arrangement affects motor location, bearing configuration, foundation dimensions and overall installation.
Can the motor be supplied for my country's voltage and frequency?
Yes. The motor can be reviewed according to the selected fan power and the required project voltage, frequency and phase.
Is the No.9D drawing valid for every W9-28 model?
No. It is provided as a representative installation drawing only. Final dimensions must be taken from the approved GA drawing for the selected W9-28 configuration.
Can QIYUE provide a GA drawing before production?
The project configuration can be reviewed from the confirmed duty point, selected fan size, drive arrangement, duct interfaces and installation conditions before final production documentation is issued.
What should I send for a high-temperature replacement fan?
Send the existing nameplate, airflow, pressure, temperature, motor data, rotation, inlet and outlet dimensions, foundation information and site photographs where available.
Send Your Hot-Gas Duty
Send airflow, pressure, continuous and peak temperature, gas composition, dust loading, voltage, frequency and installation information. QIYUE FAN can review the suitable W9-28 configuration before quotation.
