Our Velocity-PV (Photovoltaic) model takes the technology of an HVLS fan one step further by adding the environmental and energy-efficient benefits of solar power. The proprietary design and auxiliary power capability creates a stand-alone operating system capable of working in nearly any climate.
Even better, the Velocity-PV does not sacrifice its effectiveness in controlling the temperature of large spaces - in fact, our 18’ ( 5.5 m) diameter Velocity-PV puts out more airflow than some competitors’ conventional 24’ (7.3 m) fans.
Renewable energy and low carbon footprint combine to provide years of reliable performance while supporting the environment and your company’s bottom line.

How Does An HVLS Fan Work

How Does An HVLS Fan Work  

 N/A The patented airfoils (blades) on the Serco VELOCITY fan produce a massive, cylindrical column of air that flows down to the floor and outward in all directions. This "horizontal floor jet" pushes air a greater distance before it begins moving vertically and is drawn back through the fan. The greater the down flow, the greater the air circulation and resulting benefits. In cooler months, the VELOCITY fan can operate in reverse, circulating hot air trapped at ceiling level and creating a warmer mix of air throughout a facility. How-Does-HVSL-Fan-Work.JPG

VELOCITY™ FAN Design Highlights

6-Blade Design

 N/A
  • Less torque than 10-blade fan - extends the life of the fan
  • 40% lighter than 10-blade fan - reduces stress on building, lowers freight cost, eases installation
  • Less fan weight reduces load on attachment points
  • Lowest and most effective Solidity ratio in the industry

Drive System / Variable Frequency Drive (VFD)

 N/A
  • Industrial-grade integrated motor/gear box assembly - lifetime rated; no maintenance
  • Advanced, programmable VFD - rated for extreme environmental conditions
  • VFD is fan mounted and factory wired- 100% operational QC check prior to shipment
  • Compliant with National Fire Protection Association (NFPA) HVLS fire safety standards

Blade-Lock Safety System™

 N/A
  • Redundant safety system that interconnects the blades, hub, drive shaft and frame
  • Blade straps and retaining collars lock blades to the hub struts and to adjacent blades
  • Safety plate attached to the frame prevents separation of hub assembly
  • Safety cables and guy wires provide additional security- further connecting the fan to the facility structure and providing extra stabilization if fan is exposed to crosswinds

Operating Controls

 N/A
  • Adjustable speed control panel with forward/off/reverse switch and remote diagnostics
  • Connection via CAT 5E cables
  • iFan™ option allows network configurator and centralized operation

Airfoil (Blade) Design

 N/A
  • NACA aerodynamic profile specifically suited for rotary airfoil applications
  • One piece, extruded anodized aluminum design
  • Generates more efficient down flow resulting in a more powerful horizontal floor jet
