Greenheck Redesigns HVLS Overhead Fans

Greenheck announced its redesigned DS-3 three-bladed and DS-6 six-bladed High Volume Low Speed (HVLS) overhead fans, expanding performance capabilities while simplifying installation and system integration. The updated models are intended for a wide range of commercial and industrial applications requiring large-area air movement.

The redesigned DS Series fans provide air performance up to 281,700 cubic feet per minute, supporting larger coverage areas and increased cooling effects of up to 15° F. These characteristics are intended to improve occupant comfort while helping reduce energy costs.

The DS-3 and DS-6 are engineered for efficiency and environmental resilience:

• Ceiling Fan Energy Index (CFEI) values up to 83% higher than minimum U.S. Department of Energy (DOE) requirements;

• Maximum operating temperature of 130° F (55° C); and

• IP66 ingress protection rating for resistance to dust and water.

The redesigned models are compatible with a broad range of control options, including ModBus RTU, BACnet MSTP, 0–10VDC, and additional control methods.

Factory-programmed controller options include economical four-speed and multispeed analog controls, supporting different operational needs and budgets.

Several features are intended to reduce installation time and setup complexity, including a factory-assembled power pack; plug-and-play wiring, reducing installation time by up to 50%; field-adjustable extension tube for quick drop-length adjustments; and automated commissioning and diagnostic test modes to support setup and operation

The redesigned Greenheck DS-3 and DS-6 HVLS fans are positioned to help contractors address airflow, comfort, and energy performance requirements while supporting faster installation and system integration.
