11kW 9-19 High-Pressure Centrifugal Blower (9-19-5.6A)
Brand Chemical Supplies offers the 9-19-5.6A high-pressure centrifugal blower, a specialized industrial machine designed for applications requiring extreme static pressure and high-velocity air movement. Unlike standard ventilation fans, the 9-19 series features a narrow, high-speed impeller capable of overcoming significant resistance, making it the industry standard for pneumatic conveying and furnace blast systems.

Key Features & Benefits
-
Exceptional Static Pressure: Engineered to deliver over 5,000 Pa of pressure, allowing this blower to push air through long, narrow ducting or through dense materials that would stall a standard fan.
-
Direct Drive Efficiency: The “Type A” configuration connects the impeller directly to the motor shaft, ensuring 100\% power transfer, reducing maintenance by eliminating belts, and providing a more compact footprint.
-
High-Strength Impeller: The forward-curved blades are precision-welded and dynamically balanced to withstand the intense centrifugal forces generated at 2900 rpm.
-
Rugged Industrial Build: The casing is constructed from reinforced heavy-gauge steel, designed to handle high-velocity air and resist the vibration associated with high-pressure operations.
-
Stable Performance Curve: Specifically designed to maintain a stable airflow even when backpressure fluctuates, ensuring consistent performance in industrial processes.
Primary Applications
-
Pneumatic Conveying: Transporting plastic pellets, grains, sawdust, or other dry granular materials through piping systems.
-
Forced Draft Systems: Providing high-pressure combustion air for industrial furnaces, kilns, and boilers.
-
Smelting & Foundries: High-pressure air injection for metal processing and forge operations.
-
Material Extraction: High-suction removal of heavy industrial dust and metallic filings.
-
Industrial Drying: Focused, high-velocity air knives for removing moisture from parts on high-speed assembly lines.
Installation & Safety Notes
-
Startup Current: Due to the 11kW motor and the inertia of the high-pressure impeller, a Star-Delta or Soft Starter is highly recommended to manage the initial electrical surge.
-
Noise Management: High-pressure blowers generate significant tonal noise due to air velocity; we recommend installation in a dedicated plant room or the use of acoustic enclosures and silencers.
-
Inlet Protection: Ensure the inlet is filtered or screened; because this unit operates at high speeds, even small debris can cause significant damage to the impeller.
