SOLAR POWERED VENTING
175Watt and 235 Watt Solar Fans
Finally a solar fan that really works
NOW AVAILABLE!
Three years of research and development have resulted in the ultimate solar powered attic fan. We've been following the various fans currently available and have also done testing on the actual output of 10 watt, 20 watt and 30 watt solar fans. Our testing has shown all of these fall short of having sufficient power to properly evacuate an attic area, especially in sunny climate.
Solturbine Solar fans:
-
175 and 235 watt systems to choose from
-
Measured cfm performance
-
14" and 16" turbine fans range from 1,100cfm to 2400cfm
-
Turbine fan makes the most use of solar power, very efficient
-
Electronically controlled brushless motor
-
Sealed ball bearing design
-
Rated for 180F air
-
Fusible link for fire safety
-
Nothing is made in China
-
Custom made roof vent allows for minimum of restriction, maximum air flow
-
Can be installed on the roof (with vent shown above), or in the gable
-
15 year motor warranty, the best in the industry
-
25 year panel warranty
-
Can be installed in any roof (tile skirts available for tile or ceramic roofs)
Shop and compare to other fans:
-
Overstated CFM claims (ten watt fan is 310cfm at noon in Phoenix Arizona)
-
12" stamped fan blades
-
Additional fans required for adequate venting (two or more per house)
-
Motors have brushes that wear out in two summers
-
No thermostat so the fan runs during the winter and shortens fan life
-
No fire safety fusible link to shut off fan in case of an attic fire
-
Bushings not sealed bearings which dry out and seize the fan
-
Motors not rated for high temperatures
-
Moving components made in China
-
Inefficient fan paddle design not very effective
-
Inefficient air flow path affects total cfm (fan blows against a flat surface)
