Semi-outdoor sports venues – covered futsal courts, school playground canopies, grandstands and stadium concourses – sit in the hardest environment for comfort cooling: open sides, heat radiating from roofs, crowds in bursts. RDF HVLS fans for playgrounds and sports fields move up to 15,197 m3/min over the covered zone using an IP64 gearless drive rated for dust and splash, at under 39 dB(A).
Why projects specify this RDF HVLS fan
- IP64 sealed, gearless motor tolerates the dust, rain splash and humidity of open-sided covered venues.
- ~1,450 m2 per 1.3 kW fan makes canopy-level coverage of courts and spectator zones viable where ducted AC never could be.
- Low-speed safety profile above active play areas, with triple-bolt anti-drop hub and safety cable.
- Comfort for intermittent crowds – switch on before events; disperse venue heat that builds under metal roofs all afternoon.
- Both 220 V and 380 V versions to match municipal school or stadium power supplies.

Airflow at maximum speed per the manufacturer type test; running speed is infinitely variable. The 5.2 m model’s printed “14 ft” in the source brochure is a brochure typo; the manufacturer’s Chinese-market spec table lists 5.2 m = 17 ft, the correct conversion.
Semi-outdoor design considerations
These installations are engineered as covered-environment fans, not weather-exposed units: the IP64 motor tolerates splash and dust but the fan should remain under a permanent canopy with the electrical connection made to outdoor-rated local code. Grandstands, swimming-pool enclosures and covered play courts are the typical scope.
Layout follows the shade structure: 6.2-7.2 m fans under high canopy roofs (8-15 m), 4.2-5.2 m units under lower school walkway and play-shelter roofs. We recommend confirming wind exposure and mounting structure with our engineering drawing before ordering for coastal or high-wind sites wind-load assessment documentation can be arranged for export projects upon request.

Frequently asked questions
Can the fan be installed outdoors?
It is IP64 rated for dust and splash and intended for covered or semi-outdoor spaces – a permanent roof or canopy is required. It is not rated for direct rain exposure or free-standing pole mounting.
Does wind interfere with it?
In open-sided venues cross-winds alter the local air pattern but do not harm the fan; structure and controller are designed for normal building wind conditions. High-wind regions require a structural check, which we support with mounting drawings.
How many fans does a covered five-a-side pitch need?
Typically one 7.2 m fan covers the court zone from a 9-12 m canopy; two 6.2-6.7 m units are used where the roof is lower or the pitch spans two bays. A canopy drawing is enough for a layout proposal.
What power supply do school venues use?
Both 220 V single-phase and 380 V three-phase are available from 6.2 m upward; municipal venues more often have three-phase, smaller school canopies single-phase.

FAQ
What does HVLS mean?
High Volume, Low Speed: large-diameter ceiling fans that move a very large air volume at low rotational speed, covering big floor areas with gentle, even airflow instead of concentrated high-speed blasts.
Why choose a PMSM direct-drive HVLS fan?
Permanent-magnet synchronous motors with direct drive run at high efficiency with fewer wearing parts than geared designs – meaning lower energy use, quieter operation and less maintenance over the fan’s life.
Which sites use HVLS ceiling fans?
Typical applications include factories, warehouses, gyms and sports halls, markets and malls, playgrounds and sports fields, and livestock farms – any large space where uniform airflow and lower energy cost matter.
How is fan size and unit count decided?
Selection comes from floor area, mounting height and the obstruction layout of the site; suppliers model diameter and placement from drawings so airflow reaches working zones evenly.
