Based on your query for an 11kW Stainless Steel High-Pressure Blower, here is a detailed breakdown of what this machine typically entails, its common applications, and key specifications you should look for.
This is a specialized piece of industrial equipment, not a standard off-the-shelf unit. It is designed for demanding environments where corrosion resistance and high static pressure are required.
Key Characteristics
- Power: 11 kW (approximately 15 HP). This indicates a high energy consumption suitable for heavy-duty, continuous operation.
- Material: Stainless Steel (SS) . Typically SS304 or SS316/L.
- Why SS? For handling corrosive fumes, salt-laden air (marine), moist gases, or clean-room environments where rust from carbon steel is unacceptable.
- Type: High-Pressure Blower (Regenerative / Side Channel) or Centrifugal.
- High Pressure typically means capable of generating 200 to 600 mbar (8 to 24 inches of water column) or more, depending on the specific impeller design.
Common Applications
Because of the stainless steel construction, this blower is used in aggressive environments:
- Wastewater Treatment: Aeration in corrosive environments (exposure to H2S gas).
- Chemical Industry: Fume extraction for corrosive gases (acids, alkalis), pneumatic conveying of chemicals.
- Food & Beverage: Drying systems, air knives for cleaning, or vacuum packaging where hygiene and corrosion resistance are mandatory (e.g., fish, meat, or dairy processing with frequent wash-downs).
- Pharmaceuticals: Clean air transfer, vacuum packaging, or dust collection where contamination must be avoided.
- Marine & Offshore: Ventilation for engine rooms or pump rooms where salt spray is present.
- Fume Extraction: Removing welding fumes or exhaust from industrial processes.
Typical Technical Specifications (Estimated)
- Motor Power: 11 kW (15 HP)
- Voltage: 3-Phase (e.g., 230V / 400V / 460V, 50 Hz or 60 Hz)
- Motor Speed: Typically 2900 RPM (50Hz) or 3450 RPM (60Hz) for direct-drive.
- Max Flow Rate: Approximately 800 - 1,200 m³/h (470 - 700 CFM) — varies significantly by model.
- Max Pressure (Blower): Approx 250 - 600 mbar (100 - 240 inH2O) — depends on single or two-stage design.
- Max Vacuum: Approx -250 to -600 mbar
- Noise Level: 70 - 85 dB(A) (depending on silencers)
- Ingress Protection: IP55 or higher (IP65 for wash-down environments).
- Connection: Flanged (DN 80, DN 100, or DN 125) or threaded.

Important Buying Considerations
- Confirm "High Pressure" vs "High Flow": Many blowers are "high flow, low pressure." You must confirm the maximum pressure (ΔP) you need in mbar or inches of water column. An 11kW SS blower can have very different impellers for pressure vs. flow.
- Stainless Steel Grade: Specify SS316 for maximum corrosion resistance (especially in chemical or marine use). SS304 is cheaper but less resistant.
- Motor Type: Ensure it is a Premium Efficiency (IE3 or IE4) motor for energy savings.
- Ambient Temperature: High-pressure blowers generate significant heat. If the air is >40°C, you may need a blower rated for higher temperatures or a special cooling fan.
- Noise: High-pressure blowers are loud. Look for units with silencers or request a low-noise enclosure.
- Certification: If used in hazardous areas (ATEX), you need an explosion-proof model (ATEX Zone 1 or 2 equivalent).
How to Specify for a Supplier
When searching for or ordering this blower, provide these exact points to a supplier:
"I need an 11 kW, 3-phase, 400V, 50 Hz, stainless steel (304 or 316) regenerative (or centrifugal) high-pressure blower. Required pressure: [X] mbar. Required flow: [Y] m³/h. Application: [e.g., chemical fume extraction]. Please provide a datasheet with performance curve."
Recommendation: Contact a specialist industrial fan distributor (like those listed above) directly with your required Pressure (P) and Flow (Q) . They will cross-reference the 11kW power with the specific SS impeller design needed to meet your exact operating point. Do not buy an 11kW blower without matching it to your system's pressure loss.
