The 9-19 Industrial Blower particularly which is a high-efficiency centrifugal fan meticulously engineered to handle high-pressure, continuous airflow operations in industrial applications. Designed and manufactured by Senotay - Hebei OuTai Environmental Protection Equipment Co., Ltd. , this blower is commonly used as a boiler induced draft (ID) fan and forced draft (FD) blower for heavy-duty industrial systems.
High-Pressure Pneumatic Displacement: SENOTAY 9-26 Centrifugal Blower
Engineered specifically for extreme resistance environments, the SENOTAY 9-26 High-Pressure Centrifugal Blower provides the intense static head required for industrial pneumatic conveying, dense material handling, and forced draft combustion. Where standard ventilation fans stall under system backpressure, the narrow, heavy-shrouded impeller geometry of the 9-26 forces air or non-corrosive gas streams through long-distance pipelines, material beds, and restrictive environmental filtration systems.
Continuous Material Moving Capacity: Designed with deep-shrouded, forward-curved steel wheels that sustain high velocity even when handling heavy particulate or solid-laden air flows.
Anti-Fatigue Scroll Housing: Built using thick-gauge plate steel with exterior structural rib reinforcements to prevent casing distortion under maximum internal pressure cycles.
Vibration-Free High RPM Alignment: Precision G2.5 balanced assemblies eliminate axial drift, protecting the dual-bearing blocks and extending motor life during continuous-run applications.
By operating our own casting, machining, and balanced-wheel assembly lines in the GuangMing District of Shenzhen, China, we bypass intermediate industrial trading markups. This factory-direct integration ensures highly competitive wholesale pricing for volume OEM equipment manufacturing and rapid plant-level retrofits.
Every 9-26 high-pressure blower is manufactured inside our ISO 9001 certified facility and carries full CE compliance. Available in high-stability drive configurations (A-type direct drive or D-type coupling) and customizable discharge orientations ($0^\circ, 90^\circ, 180^\circ, 270^\circ$), these units drop into existing technical foundations without ductwork modification.
A high-pressure blower failure instantly halts pneumatic transport and factory production. To prevent costly downtime, standard geometries and custom industrial batch orders ship out directly from our regional logistics nodes within 48 to 72 hours.
SENOTAY provides direct engineering consultation for pressure-drop calculations, fluid dynamics optimization, and motor power matching. Our factory maintains a constant inventory of all companion wear components—including replacement impellers, custom sealing gaskets, water-cooled bearing boxes, and vibration-damping assemblies—ensuring streamlined single-source support for industrial environmental and material handling equipment worldwide.

The 9-19 blower operates on the centrifugal force principle.
Air Inlet: Air enters through the inlet at the center of the impeller.
Centrifugal Acceleration: As the impeller rotates, it accelerates the air radially outward.
Kinetic-to-Pressure Conversion: The increasing velocity converts kinetic energy into static pressure within the volute casing.
Outlet Flow: The compressed air is discharged through the outlet, ensuring consistent flow for combustion, ventilation, or material conveyance.
This design provides steady, balanced airflow even under varying pressures, making the 9-19 High Pressure Centrifugal Fan efficient and reliable for continuous operation.
