Review on Lasko Twin Electric Window Fan with Reverse Functionality, EA by Beth Clark

When you need to move a lot of air in or out of a room or group of rooms, you need a fan that can move as much air as possible.With short blades and wide open gaps around the blades of these fans, the volume of air flowing through the fan is far from its potential.In one room, down a short hallway and in another room no air movement is felt in any of the rooms, only when air is sucked in is there air movement felt, and even then ONLY in a direct line with the fans and not at all in the hallway or window of another room With a claimed maximum air volume of 1000 cfm, it's impossible to tell outside of a 1000 cfm room.typical bathroom.This fan would be with a few minor modifications much more efficient, not least 2 inch larger vane sets in the existing housing.
