It seems you are describing a specific type of centrifugal blower with particular technical parameters. Let me break down what these specifications mean and help you identify or source this component.
Based on your description:
- Medium Pressure (typically 1000–3000 Pa)
- Antifraying (prevents fiber/string from being pulled into the motor or bearings)
- 2819 Pa (2.8 kPa operating pressure)
- Centrifugal (radial impeller)
- Cooling Blower (used for air movement, often in electronics or machinery)
What This Specification Tells Us
| Parameter | Meaning | Typical Application |
|---|---|---|
| 2819 Pa | ~0.41 PSI static pressure | Moderate resistance systems (filtered intakes, ducting) |
| Medium Pressure | 1–5 kPa range | Industrial cooling, ventilation |
| Antifraying | Sealed motor / shielded inlet | Textile, paper, CNC dust extraction |
| Centrifugal | Radial airflow | High static pressure vs axial fans |
Common Applications
- Textile machinery (keeps fibers out of motor)
- CNC router/spindle cooling
- Electronics cabinet cooling with dust filters
- 3D printer enclosure ventilation
- Laboratory fume hoods (low-to-medium pressure)
If You're Looking to Purchase or Match This Unit
Critical specs to verify:
- Airflow (CFM/m³/h) – Not given. A 2819 Pa centrifugal blower could flow anywhere from 50–500 CFM depending on impeller size.
- Voltage – 24V DC, 48V DC, or 115/230V AC?
- Inlet/Outlet size – Usually 70–150mm diameter for this pressure range.
- Motor type – EC (electronically commutated) or shaded pole?
Possible Known Models That Fit This Description
- Sanyo Denki San Ace C series (antifraying variants available)
- ebm-papst R4E or RG series (medium pressure, protection class)
- Delta AFB or PFB series (custom antifraying options)
- Sifan or Mechatronics industrial blowers
Antifraying Construction Typically Includes:
- Closed motor housing (no exposed windings)
- Inlet grille with ≤1mm mesh
- Sealed bearings (2RS or contact seals)
- Optional: PTFE shaft seal
If You Need Help Identifying a Specific Part Number:
Please provide any additional markings from the blower:
- Brand/logo
- 6–10 character model code
- Voltage/amps
- Date code
Or if you need a replacement:
- Exact dimensions (length, width, height, inlet/outlet diameter)
- Connection type (leads, terminal block, connector)
- Ambient temperature range
Would you like help finding a supplier, calculating the required CFM for your application, or identifying a specific model from photos?
