Greenheck has redesigned its DS-3 three-bladed and DS-6 six-bladed High Volume Low Speed (HVLS) overhead fans to provide higher air performance up to 281,700 cfm, larger coverage areas, and increased cooling effects up to 15 degrees F., improving comfort and reducing energy costs.
Both models achieve Ceiling Fan Energy Index (CFEI) values up to 83% higher than the minimum Department of Energy requirements. Each is rated for a maximum operating temperature of 130 degrees F. and carries an IP66 ingress protection rating for protection against dust and water in extreme conditions. Both are compatible with a range of control options, including ModBus RTU, BACnet MSTP, 0-10VDC, and more.
