Your query appears to be a product search or specification request for an industrial centrifugal fan. Here is a breakdown of the key terms and typical considerations for sourcing such a unit.

Product Specification Breakdown

• Wholesale: You are looking for bulk pricing (B2B), likely from a manufacturer or direct distributor.
• Free Standing: The fan has a base or feet for floor mounting, as opposed to being duct-mounted or a plug fan. It is typically self-contained.
• 1450rpm: This is the rotational speed. This is a standard 4-pole motor speed (at 50Hz mains frequency). It indicates a medium-speed fan (between 900rpm low-speed and 2900rpm high-speed). This speed is common for high static pressure applications.
• Stainless Steel (SS): The impeller (wheel) and often the housing are made of Stainless Steel (typically SS304 or SS316). This implies the fan is for demanding environments: corrosive fumes, humidity, food processing, chemical labs, or marine applications.
• Customized: The manufacturer will adjust dimensions (inlet/outlet size, motor power, base height, coating) to your specific airflow (CFM/m³/h) and static pressure (Pa/in.WG) requirements.
• Centrifugal Fan: This is the primary type. Air enters axially and exits radially (90-degree turn). Used for high pressure duct systems.

Key Considerations for Sourcing

To get an accurate quotation, you must provide these parameters to suppliers:

1. Air Volume (Flow Rate) : e.g., 5,000 m³/h or 3,000 CFM.
2. Total Static Pressure: e.g., 800 Pa or 3 inches of water gauge.
3. Standard vs. High Efficiency: Standard designs (e.g., Backward Inclined) vs. High Efficiency (e.g., Airfoil or Backward Curved).
4. Motor: Power (kW/HP), Voltage (380V/415V/220V/440V), Frequency (50Hz/60Hz), IP rating (IP55/IP54), Insulation Class (F/H).
5. Stainless Steel Grade: SS304 (general chemical resistance) or SS316 (superior resistance to chlorides, salt water, acidic fumes).
6. Accessories: Inlet/outlet flanges, vibration isolators, safety guards, silencers, VFD (Variable Frequency Drive) compatibility, anti-spark construction (if handling flammable gases).
7. Documentation: CE, UL, ATEX (for explosive environments), ISO test certificates.

Typical Applications for this Fan Type

• Chemical Fume Extraction: Exhausting corrosive gases from labs or plating tanks.
• HVAC Systems: High-pressure air supply in commercial buildings (if in clean air).
• Dust Collection: For fine, non-explosive dusts where sparking might be a risk.
• Marine & Offshore: Saltwater corrosion resistance.
• Food & Beverage: Ventilation of steam, heat, and wash-down areas.

Finding Wholesale Suppliers (General Guidance)

You would typically search for these suppliers:

• Alibaba / Made-in-China: Search for stainless steel centrifugal fan 1450rpm or customized SS centrifugal fan.
• Industrial Fan Manufacturers: Look for companies specializing in Turbofan, Double Inlet, or Backward Curved designs.
• Distributors: Contact local HVAC or industrial equipment distributors who represent brands like Systemair, Novenco, Greenheck, or Cincinnati Fan (note: these brands often have standard lines, but "customized" implies a bespoke order).

Sample Inquiry Template

To get the best response from suppliers, send this:

"We are looking for wholesale pricing on a Free Standing Centrifugal Fan. Specifications:

• Material: Stainless Steel (please quote for SS304 and SS316)
• Speed: 1450 RPM (fixed speed or VFD capable)
• Customization: Inlet/Outlet size to be customized to [your size]. Motor power to be optimized for [your CFM/Static Pressure].
• Application: [e.g., Fume extraction from HCl tanks]

Please provide a quotation for 5 units and 20 units, including motor specifications, weight, dimensions, and delivery lead time. Also confirm if the impeller is fully welded stainless steel."

Note: Because you used the term "free standing," ensure the fan base is sufficiently heavy or has provisions for bolting down (vibration damping) to prevent movement during operation at 1450 rpm.
