The icon is a picture of a fan. The fan is more like an ancient one, not one powered by electricity. It is a flat surface that can be held and swung to produce air flow to a direction.
This is a Hand Fan icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,700 icons, all in the same style and quality.
