New and never used Greenheck exhaust fan set for sale. Includes one Greenheck Control Damper ( Model : VCD-20, size : 18” x 18”) With Belimo Actuator (model : LMB24-3), one Greenheck Roof Curb for 30 In. Square Base, 18 In. High (Model : GPI-30-18-G12 , Size: 30”x30”x12”), and one Greenheck Centrifugal Downblast Exhaust Fan (Model : GB-180-7-X). $1500 OBO
The Greenheck exhaust fans have motorized louvers. When the fans are turned on, the louvers automatically open to allow maximum ventilation. When the fans are turned off, the louvers automatically close to minimize drafts.
We have a Production facility here in Miramar where we have no air-conditioning, nor heat. We use the exhaust fans to draw air through the space and up through the roof where are most of the heat gain is.
These run at a moderate, fixed CFM, so they draw lots of air upward and it makes the environment very comfortable and are inexpensive to run all day.
