Based on your specifications, you are looking for a Low Pressure (198 ~ 1300 Pa), Material Handling blower fan made of Carbon Steel.
Given the pressure range (up to 1300 Pa, which is relatively low for a "material handling" fan), you are likely looking for an Industrial Exhaust Fan or a Backward/Forward Curved Centrifugal Fan with an open wheel design (also known as a paddle wheel or radial blade).
Here is a breakdown of the fan types that fit this description and where you would source them.
The Best Fan Type: Heavy-Duty Radial Blade (Paddle Wheel)
This is the standard for material handling. The straight radial blades prevent material from sticking.
- Pressure Match: These fans typically operate in the 1" to 8" w.g. (250 to 2000 Pa) range, so your 1300 Pa max fits perfectly.
- Material: Carbon Steel (often with a wear liner or thicker gauge).
- Key Specs to Look For:
- Wheel Type: Radial Blade (Open).
- Material: A36 or AR (Abrasion Resistant) Carbon Steel.
- Drive: Direct Drive (for speed control) or Belt Drive (for torque).
- Common Use: Conveying wood chips, dust, trim, light granular materials.
The Alternative: Airfoil/Backward Inclined (for cleaner air)
If your "material" is very light (dust, fibers) and not heavy (chunks, scrap), a Backward Inclined fan is more efficient.
- Pressure Match: Very good (500 - 2000 Pa).
- Material: Carbon Steel (standard).
- Risk: Backward curved wheels clog easily with stringy or sticky material. Avoid for "handling" heavy debris.
Centrifugal Blower (Direct Drive) - Plug Fans
For lower pressure applications (198~500 Pa), a compact Centrifugal blower with an open inlet might work.
- Pressure Match: Can handle 200-600 Pa easily.
- Material: Mild Steel / Carbon Steel housing.
- Limitation: May struggle with high-volume throughput of solid material. Best for pneumatic conveying of fine powders.
Where to find this specific fan (Sourcing)
You need to search for an Industrial Radial Blade Fan or Material Handling Fan.
Standard Manufacturers (Check product catalogs):
- New York Blower (NYB): Their "Radial Blade" or "LS" series. They have specific carbon steel models for 500-1500 Pa.
- Greenheck: Look at their "SWSI" (Single Width Single Inlet) material handling fans. Model BI (Backward Inclined) for clean air or RM (Radial Material Handling).
- Cincinnati Fan: Their "HP" (High Pressure) series radial bladed fans. They offer carbon steel as standard.
- Howden / Twin City Fan: Look for "Material Handling Fans" (MHF series).
Search Query (for online or supplier):
- "Industrial low pressure radial blade fan 1300 pa carbon steel"
- "Material handling centrifugal fan 4 inch static pressure"
- "Open wheel paddle blower carbon steel"
- "Pneumatic conveying fan 1300 Pa"
Important Sizing Check
You have specified Pressure (198~1300 Pa) and Material, but you are missing Airflow (CFM or m³/h).
- A fan that moves 500 CFM at 1300 Pa is very small (e.g., 1.5 HP motor).
- A fan that moves 5000 CFM at 1300 Pa is a much larger unit (e.g., 10-15 HP).
Without CFM, no manufacturer can quote you a specific model. If you provide the required airflow, I can help you narrow down the specific diameter and RPM required.
Final Recommendation
Go with a Radial Blade (Paddle Wheel) Fan.
- Housing: Carbon Steel (welded steel construction).
- Wheel: Open radial type (no shroud) to pass material.
- Pressure Range: You need a Direct Drive unit with a Variable Frequency Drive (VFD) to control RPM from 198 Pa to 1300 Pa. A belt drive unit will be more flexible for material handling because you can change speed easily.
Warning: Standard "HVAC" blowers (forward curved) will clog and fail if you put solid material through them. Do not use a standard furnace blower.
