The 10-18 high-pressure centrifugal fan is designed for forced ventilation, furnace air supply and industrial air-moving duties requiring comparatively high pressure. The published series covers sizes 4A through 22.4F with A, D and F arrangements.
Published performance extends from 852 to 109,890 m³/h with total pressure up to 22,142 Pa. Fan selection should be based on the required operating point, gas conditions and system resistance.
High Pressure Across a Wide Model Range
The 10-18 series extends from compact 4A direct-drive configurations to large 22.4F configurations. Published rotational speeds include 730, 960, 1450 and 2900 r/min depending on fan size.
Each fan size contains several published duty points. The minimum and maximum values below summarize the original performance tables and are intended for preliminary model screening rather than final fan selection.

10-18 Performance Range by Fan Size
The ranges below are consolidated from the original 10-18 performance tables. Where more than one rotational speed is listed for the same fan size, the range includes all published operating points for that model.
Outline & Installation Reference
The technical drawing shows the casing, motor position, inlet and outlet interfaces, mounting arrangement and dimensional references used for installation.
The original manual uses shared installation-reference drawings for the 10-18, 9-18 and 9-16 high-pressure centrifugal fan families. Final project dimensions must therefore be confirmed for the selected 10-18 model before fabrication or site installation.
Multiple Outlet Directions
The installation reference includes multiple right-hand discharge positions. Final orientation should be specified when placing the order so the casing and project interface can be checked together.
High-Pressure Air Supply & Material Conveying
Cupola Furnaces
Forced-air applications associated with medium and small cupola furnace systems.
Combustion Furnaces
High-pressure combustion-air and forced-ventilation duties.
Oil-Fired Furnace Air
Positive-pressure oil-fired furnace ventilation where the required duty falls within the published range.
Material & Grain Conveying
Pneumatic conveying applications subject to gas and material compatibility checks.
Standard Gas Conditions
Select the 10-18 by Actual Duty Point
The same fan size may contain several published operating points, and some models are listed at more than one rotational speed. Selection should therefore start with the required airflow and pressure rather than model diameter alone.

10-18 High-Pressure Centrifugal Fan FAQ
What is the airflow range of the 10-18 fan?
Across the published 4A–22.4F data, airflow ranges from approximately 852 to 109,890 m³/h.
What is the maximum published total pressure?
The highest operating point shown in the supplied 10-18 performance tables is approximately 22,142 Pa.
Which fan sizes are available?
Published sizes include 4A, 4.5A, 5A, 5.6A, 6.3A, 7.1D, 8D, 9D, 10D, 11.2D, 12.5D, 14D, 16D, 18F, 20F and 22.4F.
What gas temperature can the standard fan handle?
The original product description specifies a standard medium temperature generally not exceeding 80°C.
What is the maximum dust-content reference?
The manual specifies dust content not greater than 150 mg/m³ for the standard application.
Can different discharge directions be supplied?
The installation reference includes Right 0°, 45°, 90°, 135°, 180° and 225° positions. Confirm the required orientation with the RFQ.
Can QIYUE FAN match project voltage and frequency?
Motor configuration can be reviewed according to the selected operating point and project voltage, frequency and phase requirements.
Can the 10-18 be used for an existing fan replacement?
Yes, subject to duty-point and interface review. Send the existing nameplate, airflow, pressure, speed, motor data, rotation and available installation dimensions.
