It sounds like you are looking for information on a SWSI (Single Width, Single Inlet) centrifugal blower designed specifically for oven wall cooling, rated at 3000 CFM, and constructed from Stainless Steel.
This is a very specific industrial fan, typically used to cool the outer skin of industrial ovens (like paint curing ovens, drying ovens, or heat treatment furnaces) to protect workers and electronics.
Because "SWSI 3000 CFM Oven Wall Cooling" sounds like a specific model number from a manufacturer (likely Howden, New York Blower, Greenheck, or a custom OEM), here is the breakdown of what this specification implies and how to find a match.
What the Specs Mean
- SWSI (Single Width, Single Inlet): The impeller has one set of blades and one air inlet on one side. This is the most common and efficient configuration for medium-pressure cooling applications. For wall cooling, you usually need ducted inlet (for fresh air) and a ducted or open discharge aimed at the oven wall.
- 3000 CFM: This is a high volume of air. It indicates a moderate to large fan (likely a 12" to 16" impeller diameter, or larger, depending on the static pressure).
- Oven Wall Cooling: The fan must handle hot, potentially humid, air from the surrounding environment or must be mounted in a hot zone. This implies a TEFC (Totally Enclosed Fan Cooled) motor and high-temperature bearings.
- Stainless Steel: The housing, impeller, and inlet cone are likely 304 or 316 Stainless Steel. This is critical for corrosion resistance from cleaning chemicals, high heat, or moisture.
Key Specifications You Need to Confirm (Before Ordering)
To find the exact SWSI 3000 CFM Stainless Steel blower, you need to ask for or verify:
- Static Pressure (SP): 3000 CFM is meaningless without pressure. Is it 0.5" wg? 2" wg? 4" wg? (Higher pressure = larger motor/more robust housing).
- Motor HP: Likely between 1 HP to 5 HP depending on the pressure. (Estimate: 3000 CFM @ 1.5" SP usually needs ~2 HP).
- Temperature Rating: Is the fan for ambient air (70°F) or is the air being moved hot? (Most SS fans are rated to 180°F standard, but need upgrades for 400°F+).
- Mounting: Is it a Plug Fan (mounts on a panel)? Direct Drive (wheel on motor shaft)? Belt Drive (adjustable speed)?
- Electrical: Voltage (208, 230, 460, 575 V) and Phase (single or 3-phase).
Where to Find This or a Replacement
Since "SWSI 3000 Cfm Oven Wall Cooling Stainless Steel Blower" is likely a specific model from a custom line, here are leading manufacturers known for this type:
| Manufacturer | Typical Model Series | Notes |
|---|---|---|
| New York Blower | DH (Heavy Duty) or AF (Airfoil) | Custom stainless builds are standard. High quality. |
| Greenheck | BSL or BISW (Industrial SS) | Good for standard oven cooling. |
| Howden | R Series or Buffalo Forge | Often used in very hot or corrosive oven environments. |
| Chicago Blower | HP or D Series | Heavy gauge SS available. |
| Cincinnati Fan | HV or PB Series | Direct drive plug fans are common for oven cooling. |
Likely Appearance & Dimensions (Estimate)
- Housing: Plated or welded Stainless Steel, likely 10ga to 14ga. No paint.
- Inlet: 12" to 16" diameter.
- Outlet: Often rectangular (e.g., 12" x 10").
- Drive: Likely Belt Drive if flexibility is needed.
- Motor: Mounted on a stainless steel base or a separate motor plate attached to the housing (to isolate heat).
What to Do Next (Best Course of Action)
- Check Nameplate: Look for a manufacturer name (e.g., New York Blower, Greenheck) and a serial number.
- Contact a Distributor: Search for "Industrial Stainless Steel Blower" distributors near you. Provide them with:
- "I need an SWSI fan, 3000 CFM, Stainless Steel, for oven wall cooling."
- "What static pressure do I need?" (Critical)
- "What is the inlet/outlet size?"
- Send Photos: If you have the old fan, take clear photos of the nameplate, motor, and mounting.
If you are looking for a general replacement spec for a bid or project, a common solution would be:
"SWSI Centrifugal Fan, Spark Resistant Construction (Type B or C), 304 Stainless Steel Housing & Wheel, 3000 CFM @ 2.0" Static Pressure, 3 HP TEFC Motor, 460V/3PH, Belt Drive, Arrangement 4 (or 10)."
Do you have the static pressure requirement or the physical dimensions (inlet/outlet size) of the existing fan? That would allow me to help you find a specific model number.
