What is the 9-26 Industrial Blower?
The 9-26 Industrial Blower is a high-pressure centrifugal fan designed for industrial air handling, ventilation, and exhaust applications. It’s engineered for demanding conditions where both air volume and elevated pressure are required. As a product of an experienced blower manufacturer, the 9-26 series delivers reliable performance across many sectors.
The 9-26 Industrial Blower is a high-pressure, single-suction centrifugal fan engineered to overcome severe system resistance in industrial ventilation, pneumatic conveying, and heavy-duty exhaust applications. Unlike standard high-volume ventilation fans, the 9-26 series features a specialized impeller and volute casing designed to generate extreme static pressure—reaching up to 16,000 Pa in its largest configurations. It reliably moves clean or non-corrosive gases at temperatures up to 80°C, making it the primary choice for deep boiler systems, long duct runs, and dense material beds where standard blowers would stall.
Extreme Static Pressure: Built specifically to overcome high resistance in complex ductwork and material conveying systems, generating pressures far beyond standard 4-72 or 4-68 ventilation blowers.
Aerodynamic Impeller Design: Precision-processed and dynamically balanced impellers (available in forward-curved, radial, or combination profiles) ensure smooth gas acceleration with minimal vibration and low acoustic noise.
Versatile Material Options: Standard construction utilizes high-strength Q355B carbon steel, with optional stainless steel or specialized anti-corrosive coatings available for harsh chemical environments.

· High Pressure Capability: The 9-26 blower is built to handle challenging pressure demands, suitable for use as a boiler induced draft fan or in systems with significant resistance.
· Wide Performance Flexibility: With multiple motor and impeller options, the blower can be optimized for different flow/pressure points — giving designers flexibility in matching system demands.
· Durable & Reliable Design: Sturdy materials, balanced impellers, and robust bearings ensure long service life even under heavy duty operation.
· Quiet & Efficient Operation: Aerodynamic optimization reduces noise and maximizes internal efficiency, reducing energy consumption.
· Certified Manufacturing: Produced under ISO 9001 quality management (common in blower industry) and possibly CE certification (vendor-specific) — supporting Authority and Trustworthiness.
· Ease of Maintenance: Modular construction, accessible inspection covers, and standard parts simplify servicing and minimizing downtime.
These features articulate benefits clearly for prospective users and strengthen trust through credible manufacturing claims.
· Working Principle: Air (or gas) enters axially into the impeller, is accelerated outward by centrifugal force, and then guided by the volute or scroll casing into the outlet. The conversion of velocity into pressure enables the blower to drive air through ductwork, filters, or process resistance.
· Structure / Components:
o Impeller / Fan Wheel — blades (forward or radial) balanced for high-speed rotation
o Casing / Scroll / Volute — collects and directs airflow, converting kinetic energy to pressure
o Motor & Drive Assembly — direct, belt, or coupling arrangements for torque transfer
o Shaft, Bearings & Seals — support rotor loads and minimize leakage
o Inlet / Outlet Flanges / Connections — integrate with ducting systems
o Frame & Mounting Base — supports the blower, ensures alignment, mitigates vibration
