Based on the keyword "8000Pa centrifugal fan" , you are likely looking for a high-pressure industrial centrifugal fan (often called a "blower") capable of generating 8 kPa (kilopascals) of static pressure.

This is a high-pressure specification. Here is the detailed breakdown of what this means, typical applications, and how to source one.

What does 8000 Pa mean?

• Conversion: 8000 Pa = 8 kPa = 08 inches of water gauge (in. w.g.) .
• Pressure Class: This places the fan firmly in the High Pressure category.
• Fan Type: Standard AC axial fans or low-cost centrifugal fans cannot achieve this. You need a specialized industrial fan.

Typical Fan Types for 8000 Pa

The two most common designs for this pressure range are:

• Backward Curved / Backward Inclined (BC/BI): Most efficient for this range. Suitable for clean air, HVAC, and drying systems.
• Forward Curved (FC): Can achieve this pressure, but typically requires a much larger fan wheel at high RPM. More prone to overload.
• Radial Blade / Paddle Wheel: Excellent for dirty air or material handling. Very robust, but less efficient.
• Ring Blower (Side Channel): These can reach 8000 Pa, but only at very low airflow (e.g., < 50 CFM). If you need high airflow, you cannot use a Ring Blower.

Key Specifications to Provide to a Supplier

To get an accurate quote, "8000 Pa" is not enough. You must provide:

1. Airflow (CFM or m³/h): A 8000 Pa fan moving 100 CFM is a small, dense blower. A fan moving 10,000 CFM at 8000 Pa is a massive industrial machine. This is the most critical missing variable.
2. Motor Power (kW/HP): Rule of thumb: To move 1,000 CFM at 8000 Pa requires roughly 5.5 kW (7.5 HP).
3. Air Density (Temperature & Altitude): 8000 Pa is much harder to achieve when moving hot air (e.g., in a furnace) or air at high altitude.
4. Gas Type: Is it clean air, dusty air, or corrosive fumes? (Dictates wheel material and design).

Common Applications

• Pneumatic Conveying: Moving plastic pellets, powders, or grains through pipes.
• Industrial Drying: High-pressure air to blow water off parts (air knives).
• Combustion Air: Supplying air to burners in boilers or furnaces.
• Baghouse / Dust Collection: Overcoming the resistance of filter bags (pulse jet systems).
• Ventilation: Long duct runs in mines or tunnels.

How to Find One (Sourcing)

Since this is an industrial spec, do not look at home improvement stores. Look for:

• Chinese Manufacturers (High Volume / Good Price):
  • Check Alibaba.com for "Backward Curved Centrifugal Fan 8kPa".
  • Look for brands from factories in Zibo, Wuxi, or Shanghai.
  • Caution: Tested pressure (Pa) vs. actual performance can differ. Ask for a certified fan curve.
• International Brands (Premium / Reliable):
  • Greenheck (BIDW series)
  • New York Blower
  • Cincinnati Fan (HP series or High Pressure Radial Blowers)
  • Systemair / Soler & Palau

Summary Advice

If you simply connect a standard 1HP fan expecting to get 8000 Pa, you will fail. This pressure requires significant shaft power.

Your next step: Calculate or estimate your required Airflow (CFM) .

• Example: If you need high pressure for air knives (low volume), a Regenerative Blower (side channel) is perfect.
• *If you need high pressure for ducting/pneumatic (high volume), you need a Backward Curved Industrial Centrifugal Fan (3-50+ HP).
