It sounds like you are looking for information on a dust collector exhaust fan with a capacity of 13,000 m³/h. This is a common size for medium-to-large industrial dust collection systems.

Below is a breakdown of what this specification means, typical applications, and key considerations for selecting or purchasing such a fan.

What does 13,000 m³/h mean?

• Airflow: 13,000 Cubic Meters per Hour.
• Conversion: This is equal to approximately 7,650 CFM (Cubic Feet per Minute), which is the standard imperial measurement in North America.
• Scale: This flow rate is suitable for systems requiring significant dust pickup, such as a central system serving multiple woodworking machines, a large pharmaceutical isolator, or a heavy-duty welding fume extraction system.

Key Factors Beyond Airflow (The "Spec Sheet")

When searching for a fan to move 13,000 m³/h, you must know the Static Pressure (ΔP) of your system. The fan's motor power (kW/HP) and speed (RPM) are determined by the pressure it must overcome.

You will typically see this written as: "13,000 m³/h @ XX Pa or mmH₂O (Water Gauge)"

• Low Pressure (100–500 Pa / 0.4"–2" WG):
  • Type: Axial Fan or High-Efficiency Plug Fan.
  • Application: Simple duct runs, general ventilation.
  • Motor: Typically 5 kW – 3 kW (2–4 HP).
• Medium Pressure (500–1500 Pa / 2"–6" WG):
  • Type: Centrifugal Fan (Backward Inclined or Airfoil).
  • Application: Typical dust collector with filter bags/cartridges and short duct runs.
  • Motor: Typically 4 kW – 7.5 kW (5–10 HP).
• High Pressure (1500–4000+ Pa / 6"–16"+ WG):
  • Type: Centrifugal Fan (Radial Blade / Material Handling).
  • Application: Long duct runs, pneumatic conveying, high-resistance filters (e.g., HEPA), very heavy dust.
  • Motor: Typically 11 kW – 22 kW (15–30 HP).

Common Applications for a 13,000 m³/h Fan

• Woodworking: Central system for 5–10 machines (planers, sanders, table saws).
• Welding & Fume Extraction: Servicing 4–8 welding stations.
• Pharmaceutical / Chemical: Isolator ventilation, dust-tight conveying.
• Agriculture: Grain dust collection, feed mill ventilation.
• Mining & Cement: Conveyor transfer points, baghouse exhaust.

What to Look for in a Specific Model

If you are purchasing a fan for a dust collector, look for these features:

• Wheel Type: For dust, use Radial (for sticky/heavy dust) or Backward Inclined (for cleaner air or moderate dust). Avoid forward-curved wheels for heavy dust.
• Housing Material: Mild Steel (painted) is standard. Stainless Steel (304/316) is required for corrosive dust (chemicals, wet scrubbers).
• Transmission: Belt-Driven is preferred for dust collectors. It allows you to change the fan speed (CFM) by changing the pulley size.
• Cleanout Door: A small door on the fan housing is essential for cleaning out built-up dust.
• Motor Rating: Must match the Amps and Voltage of your facility (e.g., 380V/3ph/50Hz or 460V/3ph/60Hz).

Example Calculation (Quick Estimate)

If you need to move 13,000 m³/h against 150 mmH₂O (approx. 6" WG) of pressure:

• Air Power (kW): $P = (Q \times P_t) / (3600 \times \eta)$
  • $Q = 13000$
  • $P_t = 1500 Pa$ (since 1mmH₂O ≈ 10 Pa)
  • Efficiency ($\eta$) = ~0.65 (65%)
• $P \approx (13000 \times 1500) / (3600 \times 0.65) \approx 19,500,000 / 2,340 \approx 8.3 kW$
• Motor Safety Factor (10-15%): $8.3 \times 1.15 \approx 9.5 kW$
• Result: You would need a ~11 kW (15 HP) motor.

Where to find specific models

To get a quotation, you would search for:

• "Dust collector fan 13000 m³/h centrifugal"
• "Industrial exhaust fan 7500 CFM"
• Brands: Greenheck, Twin City, New York Blower, Howden, Ventilation, or local industrial fan manufacturers.

To provide a specific recommendation, I need the following:

1. Static Pressure (mmH₂O or Pa) the fan must overcome.
2. Type of dust (e.g., wood chips, fine powder, metal fume, explosive dust).
3. Voltage and Frequency (e.g., 380V 50Hz 3-phase).
4. Expected temperature (ambient or hot exhaust).

Without the pressure, a 13,000 m³/h fan could be a small axial fan (~1.5 kW) or a massive heavy-duty centrifugal fan (>20 kW).

Let me know the pressure, and I can help narrow it down further.
