20 Foot HVLS Ceiling Fan | 6 Blades | 10,700 Square Foot Coverage | 208-240V or 380-480V

Product Overview

This is a 20-foot diameter HVLS ceiling fan with six aluminum blades and a silver finish. The fan is designed for large commercial and industrial spaces requiring high-volume, low-speed air movement.

It operates with a variable speed controller mounted on the wall, using a VFD. The fan is compatible with both single-phase and three-phase power at 208-240V or 380-480V, and supports 50 or 60 Hz frequency.

The fan uses a 1.5 HP (1100 Watt) PMSM motor and includes a 39-inch downrod for mounting. The total fan weight is 297 lbs.

Maximum airflow is 406,119 CFM, with a coverage area of up to 10,700 square feet. The maximum speed is 65 RPM, and the sound level is rated at 38 dB.

Where This Product Fits Best

This fan is suitable for large open spaces such as warehouses, manufacturing plants, distribution centers, and sports venues. The 20-foot diameter and high CFM output are designed for environments where broad, even air movement is required.

It is compatible with electrical systems operating at 208-240V or 380-480V, in either single-phase or three-phase configurations. The fan can be used in facilities with ceiling heights and structural support capable of handling a 297 lb fixture and a 39-inch downrod.

The IP55 rating on the fan and IP66 rating on the controller allow for installation in areas where exposure to dust and water jets may occur, but not in locations requiring full submersion or washdown.

Applications include temperature equalization, occupant comfort, and condensation control in large, open-plan facilities.

Performance and Functional Considerations

The fan delivers up to 406,119 CFM at a maximum speed of 65 RPM, providing coverage for up to 10,700 square feet. The variable speed controller allows adjustment to match airflow requirements for different conditions or occupancy levels.

The 1.5 HP PMSM motor is designed for continuous operation in demanding environments. The six-blade aluminum design balances airflow efficiency with low sound output, rated at 38 dB.

The fan supports both 50 Hz and 60 Hz operation, making it compatible with a range of electrical systems. The wall-mounted VFD controller provides direct, local control of fan speed and operation.

The IP55 rating on the fan protects against dust ingress and water jets, while the controller?s IP66 rating allows for installation in areas exposed to heavier water spray or dust.

Installation and Long-Term Use

The fan is supplied with a 39-inch downrod for ceiling mounting. Structural support must be verified to accommodate the 297 lb weight and dynamic loads during operation.

Electrical connection requires 208-240V or 380-480V supply, in either single-phase or three-phase. The wall-mounted VFD controller should be installed within reach of the fan?s power circuit and in a location suitable for IP66 equipment.

Routine inspection of mounting hardware, blade condition, and electrical connections is recommended for long-term reliability. The aluminum blades are resistant to corrosion and suitable for most industrial environments.

Sound output is low for a fan of this size, supporting use in occupied spaces where noise is a concern. The variable speed function allows adjustment for seasonal or operational changes without physical intervention at the fan.

How This Fixture Is Commonly Used

Once installed, the fan is typically operated using the wall-mounted VFD controller. You can adjust the speed to increase or decrease airflow as needed for occupant comfort or process requirements.

The large coverage area allows a single fan to serve a significant portion of an open space, reducing the need for multiple smaller fans. The low sound level means the fan can run during shifts without disrupting communication or workflow.

The aluminum blades require minimal maintenance and can be cleaned as part of routine facility upkeep. The fan?s IP55 rating allows for operation in areas where dust or occasional water spray is present, without requiring special protection measures.

In day-to-day use, the fan is relied on for consistent air movement, temperature balancing, and condensation control. Adjustments to speed or operation can be made directly at the controller as facility needs change.

Safety, Certifications, and Warranty

The fan carries an IP55 rating, allowing operation in environments with dust and water jets. The controller is rated IP66 for protection against heavy dust and water spray.

The fan is covered by a 2-year warranty from LED Lighting Supply.

All installation and maintenance should follow standard safety practices for overhead equipment and electrical systems.
