Solar Ventilation Fan SVT-224S Stainless Steel w/ Battery - Roof, Boat, RV Vent

Description

The Sunvent SVT-224S provides continuous ventilation during the day or night with a built in Ni-MH rechargeable battery. No wiring, plugs, or noise. The housing is constructed of durable stainless steel and the clear cover protects the solar panel while keeping water and back drafts out. The vent can be used as an intake or exhaust by swapping the two included fan blades. A switch inside the Sunvent allows it to be turned on and off. It is very easy to mount and requires a 4.75" diameter installation hole.
Calculate Ventilation Rate:
The Sunvent extracts 680 cubic feet of air per hour under normal working conditions. To calculate how quickly this will ventilate an area, measure the length, width, and height (in feet), and multiply these numbers to obtain cubic feet. Divide the area's total cubic feet by 680 and multiply by 60. The result is the number of minutes required to completely cycle the air in your area.
Example:
An RV is 15ft. long, 5.5ft. wide, and 6ft. high:
15 x 5.5 x 6 = 495 Cubic Feet
495 ÷ 680 = 0.73 Hours
0.73 x 60 = 43.8 Minutes
