High Volume Low Speed

The High Volume Low Speed (HVLS) fan is ideal for heating and cooling in a variety of commercial and industrial applications, providing a constant flow of air throughout a space for sensible cooling and de-stratification of warm air pockets near the ceiling. The HVLS fan efficiently and quietly moves a large volume of air at a low operating cost.

Available in 3-Blade and 6-Blade configurations
Range from 8 to 24 foot diameter
Operates on 1 to 2 horsepower, capable of moving nearly 275,000 CFM
Used year-round with benefits in both heating and cooling conditions
Quiet and efficient operation with minimal maintenance required
Low operating expenses, costs approximately 6 cents/hour for one fan at 0.75 kW
User friendly controls with wall-mounted LCD screen
Creates a non-disruptive laminar airflow above floor level to provide effective summer cooling
Provides destratification at lower speeds, or reverse rotation during heating months
Reduces the recovery time when overhead doors are open via a constant flow of air throughout the space
Eliminates the need for noisy “man-cooler” type fans throughout the facility
Will not interfere or disrupt make-up air, heating or air conditioning systems
Motor mount assembly constructed of 1/8" thick epoxy-coated steel and grade 8 hardware
All mounts constructed of 1/4" thick epoxy-coated steel and grade 8 hardware
Safety clips prevent rotor or blade from falling in an unlikely failure of the hub or drive system
Variable frequency drive provides soft start and full variable speed operation
Operated manually, automatically or via building management systems
Emergency shutdown feature interlocks with the building fire alarm panel
Real-time status of fan speed, space temperature and status via digital interface with wall-mounted LCD screen
Microprocessor-based controls provide customizable options

F-HVLS Models are ETL Listed under file number 104224395ATL-001A and conform to ANSI/UL Standard 507 and CAN/CSA C22.2 No. 113.

Noise level is measured 6 m (20 ft) at blade height and 6 m (20 ft) horizontally from blade centre.

Maximum effective diameter is where horizontal air speed at 1.2 m (3.9 ft) above floor drops below 0.2 m/s (0.7 fps) in an empty room.

Specifications may vary due to electrical and environmental conditions.
Specifications subject to change without notice.
