Portable Evaporative Air Cooling Fan with Universal Pulley

· Active cooling: Portable Cooling Fan (yes, evaporation + ice), central AC (yes, compressor refrigeration), industrial high‑volume fan (no, only air movement).

· Acquisition cost (equal coverage): Portable Cooling Fan is 1/10 of central AC; central AC is high; industrial fan is medium.

· Installation work: Portable Cooling Fan – none, place and use; central AC requires ductwork, piping, electrical lasts 1‑2 months; industrial fan needs mounting brackets and wiring.

· Operating electricity cost: Portable Cooling Fan is low; central AC is high; industrial fan is low.

· Suitable for semi‑open spaces: Portable Cooling Fan – yes; central AC no (cooling loss); industrial fan – yes but no cooling effect.

· Routine maintenance: Portable Cooling Fan – only wet‑pad cleaning; central AC requires professional servicing (compressor, refrigerant, filters); industrial fan needs motor and bearing lubrication.

1. Housing – metal frame with ABS engineering plastic panels. The internal galvanised‑steel frame ensures rigidity and resists deformation during movement. The external ABS panels provide impact resistance, corrosion resistance, and rust‑proofing, adapting to dusty, humid, or mildly corrosive atmospheres.

2. Motor and electrical system – industrial‑grade protection. The motor is sealed against dust and moisture; all critical electrical connections are insulated. The unit can be placed directly in areas subject to floor washing or airborne particulates without requiring additional enclosures.

3. Wet pad – high‑efficiency evaporative medium. The pad material is hydrophilic‑treated to ensure uniform water distribution and maximise air‑water contact. The air path is flow‑optimised to reduce pressure drop while enhancing heat exchange efficiency.

1. ABS engineering plastic: Weather‑resistant grade, anti‑UV, non‑brittle over time – outperforms painted steel in humid and high‑temperature environments.

2. Metal frame: Galvanised steel for load‑bearing strength and torsional resistance, ensuring structural integrity during repeated relocation.

3. Wet‑pad fibre: High‑absorbency, anti‑mould composite fibre that inhibits bacterial growth, ensuring clean air delivery and extending pad replacement intervals.

4. Ice‑crystal box: Encapsulated phase‑change material, rechargeable via freezing; releases stored cooling energy without extra electricity consumption.

1. Injection moulding and assembly: In‑house 50 injection‑moulding machines ensure precision and dimensional consistency for all plastic components.

2. Production line testing: Each unit undergoes four mandatory checks before shipment: airflow test, insulation/withstand voltage test, leakage test, and running noise measurement.

3. Supply chain control: Core components (motors, wet pads, pumps) are sourced from long‑vetted suppliers with incoming material inspection.

4. Third‑party certifications: The product series holds CE, CB, GS, REACH, ROHS 2.0, CCC, and EMC certifications, meeting export requirements for Europe, Asia, Africa, and other regions.

1. Deliver the unit to site and remove packaging.

2. Connect to a 220 V single‑phase power outlet.

3. Fill the water tank (insert pre‑frozen ice‑crystal boxes if enhanced cooling is desired).

4. Switch on and select the fan speed; the unit immediately begins operation.

1. The only consumable is the wet‑pad filter; clean it every 2–4 weeks (depending on usage) by rinsing with clean water and air‑drying before reinstalling.

2. The water tank and pump require no special servicing; for extended storage, drain the tank and wipe the interior dry.

3. With no compressor, refrigerant, or valve assemblies, the unit has few failure points, making maintenance considerably less demanding than that of central air‑conditioning systems.

1. Factory workshops (machining, assembly, injection moulding): Equipment heat, dense personnel – position near production lines; one unit per 50–60 m².

2. Logistics warehouses: Poor ventilation, roof radiant heat focus on operator areas and loading/unloading docks.

3. Subway platforms (semi‑open): Stuffy waiting areas space units along both sides, coordinating with station ventilation.

4. Shopping mall atriums and walkways: Glass‑roof radiation, insufficient AC coverage activate before holidays and weekends; store away during off‑peak.

5. Gymnasiums, exhibition halls: Transient occupancy peaks, temporary events calculate quantity based on spectator area; remove after events.

6. Outdoor temporary sites (exhibition tents, construction rest areas): No pre‑installed cooling; plug‑and‑play wherever power is available.

1. The company holds over 20 utility and design patents.

2. In 2024, it was named one of Cixi's Top 100 Enterprises.

3. Long‑term ODM/OEM partner for renowned brands such as Midea, Diamond, Xiaoxiong, DCG, and ARGO, demonstrating large‑order delivery capability and consistent quality.

Q1: How does ambient humidity affect cooling performance?
Evaporative cooling efficiency is inversely related to relative humidity. At humidity below 50 %, the temperature drop reaches 5–8 °C; at 70 %, it is approximately 3–5 °C; above 80 %, the effect diminishes. Buyers can evaluate expected benefits based on local summer humidity data. In high‑humidity regions, using the ice‑crystal box more frequently can enhance auxiliary cooling for your Portable Cooling Fan.

Q2: What are the approximate acquisition and operating costs per unit?
Acquisition cost is roughly one‑tenth that of a central AC system covering the same area. Operating electricity cost depends on local tariffs and runtime but is generally estimated at 1/5 to 1/3 of the equivalent central AC zone expense. Specific figures can be provided upon enquiry.

Q3: Is the 100 m² coverage applicable to all scenarios?
The 50–100 m² range is measured under standard laboratory conditions. In real industrial or commercial settings with substantial heat‑generating equipment, high occupant density, or direct solar gain, effective coverage will be lower. We recommend planning with a conservative density of approximately one Portable Cooling Fan per 60 m² and adding redundancy for high‑load areas.

Q4: What is the noise level during operation?
As an industrial‑grade high‑airflow unit, noise is higher than that of domestic fans but significantly lower than that of industrial air compressors. In environments with high background noise, the unit's noise is usually not an added disturbance. For quieter spaces, position the units at the periphery, away from seating areas.

Q5: Does the ice‑crystal box require periodic replacement?
No – the ice‑crystal box is a sealed phase‑change material that can be reused indefinitely. Simply freeze it for 4–6 hours before each use. The water tank holds enough for 4–6 hours of continuous operation; a low‑water indicator prompts refilling, and operation resumes immediately after topping up.

Q6: How is after‑sales support handled for international customers?
Jianhui serves global clients through ODM/OEM arrangements. Depending on order volume, we can supply spare parts lists, operation/maintenance manuals, and remote technical guidance. For large‑quantity orders, we can negotiate on‑site training or factory‑based support. Specific terms are customised based on order size and collaboration model.

1. Product specification sheets and certification documents (including CE, CB, GS, ROHS, etc.).

2. Equipment selection and quantity calculation based on your space dimensions and climate data.

3. Sample unit shipment or factory inspection arrangements.

4. Delivery commitments and shipping coordination for bulk orders.
