Mobile HVLS Industrial Fans – Generic Technical Breakdown
By Motor Type
| Motor Type | Key Features | Advantages | Typical Applications |
|---|---|---|---|
| Induction (Asynchronous) | Traditional squirrel-cage rotor, simple construction | Low cost, proven tech, easy maintenance | General workshops, warehouses, short-term temporary jobs |
| Permanent-Magnet Synchronous (PMSM) | Rare-earth permanent magnets, high efficiency | ≥30 % energy saving, compact, maintenance-free, low noise | High-end manufacturing, gyms, hospitals, libraries |
By Mobility Design
| Structure | Construction Highlights | Characteristics | Typical Applications |
|---|---|---|---|
| Hand-Push Vertical | Single vertical mast + swivel casters with brakes | One-person push, plug-and-play, no installation required | Workshops, exhibitions, outdoor events, pop-up storage |
| Post-Mounted Mobile | Detachable post + weighted base + casters | Low center of gravity, stable, long-term yet movable | Large warehouses, logistics centers where ceiling mounting is impossible |
Key Performance Ranges (Representative Models)
| Parameter | Common Range | Notes |
|---|---|---|
| Fan Diameter | 1.2 m – 2.4 m | 48 in – 96 in |
| Airflow | 30 000 – 45 000 m³/h | Depends on diameter, speed, blade design |
| Power | 0.5 kW – 1.5 kW | PMSM units typically lower |
| Noise | 38 – 55 dB(A) | PMSM models usually < 45 dB |
| Coverage Radius | 8 – 20 m | Based on mounting height and blade geometry |
| Total Weight | 80 – 150 kg | Includes base and ballast |
| Power Supply | 220 V single-phase / 380 V three-phase | Field-switchable |
Standard Functions & Safety Features
| Category | Key Points | Description |
|---|---|---|
| Mobility | Swivel casters + brakes | 4–6 wheel layout, single-person maneuverable |
| Control | VFD stepless speed + remote control | Soft start, 5–8 speed settings |
| Safety | Guard ring, collision bumper, tip-over switch, thermal protection | Meets GB/T 19001 & CE requirements |
| Environment | ≥ IP54 protection | Optional rain, dust, corrosion-resistant coatings |
| Maintenance | Induction motors need periodic lubrication; PMSM maintenance-free | < 1 h annual maintenance |
Quick Application Guide
| Scenario | Recommended Diameter | Recommended Motor | Notes |
|---|---|---|---|
| Temporary warehouse < 500 m² | 1.2 m | Induction or PMSM | 1–2 units sufficient |
| Assembly workshop 500–1 000 m² | 1.5–1.8 m | PMSM | Energy-saving & quiet |
| Logistics center > 1 000 m² | 2.0–2.4 m | PMSM | Multiple units, zone control |
| Outdoor fairs / events | 1.5 m | Induction | Low cost, rental-friendly |
Usage Tips
- Estimate diameter and quantity from floor area and mounting height.
- Prefer PMSM for low-noise or 24 / 7 operation.
- Choose induction motors to minimize initial cost for short-term or rental use.
