10% large volume than general fan without cone.
15% -20% efficiency higher
special butterfly design be more beautiful and money saving
When the two semicircle shutter doors are closed, the rubber sealing ring gets good airtightness.If some fans stop running, this can avoid air pass through them, which ensures air only pass through cooling pads or air inlets.
