Got thisPORTAL Airbar™ Window Fan. It works well to pull the hot air outside. It does help to cool a small room and circulate the air in the room. It was easy to install and easy to use.its a pretty good fan for its size but it's more a small to medium room fan.i want to thank@TryItSampling&@Shaper image for giving me this opportunity to try this fan I'm using it to pull the hot air outside cause u can switch it from blowing in to blowing out the air .I was really impressed  with this fan.
