Industrial Air Movement Solution

For facilities that require comprehensive air circulation across expansive floor plans, this 20-foot HVLS ceiling fan delivers exceptional performance with its six-blade aluminum construction. Built for environments where consistent airflow is critical, the unit moves an impressive 137,000 CFM while maintaining whisper-quiet operation below 59 dBA.

Engineered to handle demanding conditions in industrial and commercial spaces, this high-volume low-speed fan covers nearly 20,000 square feet from a single mounting point. With its robust 1.5 HP motor and variable speed control through a wall-mounted VFD, operators gain precise command over air movement without the energy penalties of traditional high-speed fans.

HVLS vs Legacy Technology

  • Moves 137,000 CFM compared to multiple high-speed fans requiring dozens of units
  • Operates at ultra-quiet 59 dBA versus noisy industrial fans exceeding 75 dBA
  • Covers 19,750 square feet from one installation point rather than requiring extensive ductwork
  • Variable speed operation provides precise control compared to fixed-speed alternatives
  • Aluminum blade construction resists corrosion better than steel fan assemblies

Why This Fixture Performs

  • Energy efficiency through low-speed, high-volume operation reduces electrical consumption compared to multiple conventional fans
  • Six-blade design optimizes air movement patterns while maintaining structural balance at low RPM
  • Minimal maintenance requirements due to low rotational speeds and quality aluminum construction extending service intervals
  • Enhanced workplace safety through improved air circulation and integrated safety features including cables and hub retention systems

Installation Guide

This model accommodates various structural mounting configurations including I-beam, Z-purlin, and open joist systems with multiple downrod extensions available from 1 to 6 feet. The installation requires minimum mounting height of 12 feet with 6 feet of ceiling clearance and 2 feet horizontal clearance from obstacles. Wall-mounted VFD controller provides convenient access for operational control while maintaining NEMA 1 protection standards for industrial environments.
