Greenheck Redesigns HVLS Overhead Fans
Greenheck has announced the redesign of its DS-3 three-bladed and DS-6 six-bladed High Volume Low Speed overhead fans, engineered to deliver significant performance advantages, reliability, advanced configurability and ease of installation for a wide range of applications.
The redesigned DS Series fans provide higher air performance up to 281,700 cfm, larger coverage areas and increased cooling effects up to 15 F, helping to improve comfort and reduce energy costs. Engineered for superior efficiency, the DS-3 and DS-6 achieve Ceiling Fan Energy Index values up to 83% higher than the minimum DOE requirements. Each model is rated for a maximum operating temperature of 130 F and carries an IP66 ingress protection rating, ensuring protection against dust and water in extreme conditions.
The DS-3 and DS-6 are compatible with the industry’s widest range of control options, including ModBus RTU, BACnet MSTP, 0-10VDC and more, and are available with a variety of factory-programmed controllers, including economical 4-speed and multispeed analog controls. A factory-assembled power pack, along with additional time-saving features like plug-and-play wiring, cut installation time in half. A field-adjustable extension tube enables quick, easy adjustments to the fan’s drop length, while automated commissioning and diagnostic test modes simplify fan setup and operation.
