The Lasko W07350 Twin Window Fan provides effective cross-ventilation by combining two independent 7 in. fans in one compact unit. Each fan can be set individually for air intake or exhaust, letting you pull in fresh air from one side and exhaust warm air from the other. A slim profile keeps the view outside the window largely unobstructed. Fits most double-hung, casement, and sliding windows. Comes fully assembled. Color: White.
