Here’s a detailed technical specification and product overview for an Efficient IP44 Centrifugal Fan with High Pressure and Customizable Flow Rate, designed for industrial, commercial, or HVAC applications where environmental protection and performance flexibility are required.
Product Overview
This centrifugal fan combines IP44 ingress protection (splash-proof, dust-protected) with high static pressure capabilities and variable flow control. It is ideal for ducted systems, ventilation in dusty or humid environments (e.g., greenhouses, workshops, cleanrooms with humidity), and material transport.
Key Specifications
| Parameter | Range / Details |
|---|---|
| Protection Rating | IP44 (Splash-proof from any direction, >1mm solid particle protection) |
| Fan Type | Forward-curved or Backward-curved centrifugal impeller |
| Max Static Pressure | 400 – 1200 Pa (customizable via motor/speed control) |
| Flow Rate (Air Volume) | 500 – 12,000 m³/h (customizable via pulley, motor speed, or VFD) |
| Motor Type | AC Induction (3-phase/1-phase) or EC (Electronically Commutated) – EC offers higher efficiency |
| Efficiency (Peak) | Up to 85% (EC motor) / 65–75% (AC motor) |
| Impeller Material | Galvanized steel, aluminum alloy, or stainless steel (304/316 for corrosive environments) |
| Housing Material | Steel with epoxy/polyester powder coating (corrosion-resistant) |
| Inlet/Outlet Size | Ø100mm – Ø630mm (custom flange options) |
| Noise Level | 55 – 75 dB(A) at 1m (depends on speed & pressure) |
| Ambient Temp | -20°C to +60°C (standard) / up to +100°C (high-temp option) |
| Control Options | VFD (0-10V / 4-20mA), 3-speed switch, or manual pulley adjustment |
Key Features
IP44 Protection
- Enclosed motor housing with sealed bearings and rubber gaskets.
- Drip-proof terminal box – prevents water ingress from hosing or condensation.
- Suitable for outdoor partial coverage, kitchens, wash-down areas, and humid basements.
High Static Pressure
- Backward-curved impeller design for high-pressure efficiency (lower noise at high ∆P).
- Ideal for overcoming long duct runs, HEPA filters, heat exchangers, or pneumatic conveying.
Customizable Flow Rate
| Method | Range | Best For |
|---|---|---|
| VFD (Variable Frequency Drive) | 10–100% | Precision control, energy saving |
| Pulley adjustment (belt-driven) | ±20% of nominal | Low-cost, fixed-speed changes |
| Multi-speed motor (tap winding) | 3 fixed speeds | Simple, low-cost installations |
Energy Efficiency
- EC (Electronically Commutated) motor option reduces power consumption by up to 30% vs. AC motors at part load.
- Impeller aerodynamics optimized via CFD (Computational Fluid Dynamics) for minimal turbulence.
Common Applications
- HVAC systems – Commercial kitchens, labs, indoor pools (high humidity).
- Industrial ventilation – Dust collection, fume extraction (non-explosive).
- Agriculture – Greenhouse ventilation (splash-proof against irrigation).
- Process cooling – Electronics enclosures, heat exchangers.
Ordering / Customization Options
When specifying, you can choose:
| Customization | Example |
|---|---|
| Flow Rate | 3,500 m³/h @ 800 Pa |
| Duct Connection | Rectangular collar with rubber seal |
| Coating | Marine-grade epoxy (C5 corrosion class) |
| Motor | 3-phase 400V, 50Hz, 2.2 kW EC motor |
| Accessories | Inlet guide vanes, vibration isolators, speed controller |
Example Datasheet (Model: CF-IP44-560)
| Parameter | Value |
|---|---|
| Inlet Ø | 560 mm |
| Max Flow | 11,000 m³/h |
| Max Pressure | 1,050 Pa |
| Motor Power | 0 kW (EC) |
| Weight | 85 kg |
| Noise | 72 dB(A) |
Engineering Considerations
- Fan Curve: Always match the fan curve (Pressure vs. Flow) with your system resistance curve (duct, filters, dampers). Oversizing leads to wasted energy.
- VFD Harmonics: For EC motors, check compatibility with your existing VFD (or use integrated EC controllers).
- IP44 Limits: Not submersible; only protects against splashing (spray water <60° angle). For direct hosing, consider IP54 or IP55.
