The airflow coming from this air curtain is like like a knife! This air curtain is awesome, and for the price you can't beat it. I have an air curtain on my front door, it has a tangential style blower. When I placed the order for the Vevor unit I selected the centrifugal type rather than the axial type blower because I am looking for maximum performance. Tangential style blowers are a middle ground between centrifugal and axial, and I am very happy I went with the centrifugal style blower, because it is a step above what I have on my front door. The airflow coming from this air curtain is very defined, and laminar, and the flow rate perfectly adequate for your standard 36" door, even with both front and back doors open this can handle the cross breeze. It is also very powerful. The back door to my establishment is at the end of a short hallway, and the suction from the air curtain drawing air inward creates a noticeable airflow toward it. With my door propped open, before I installed the air curtain I could very easily feel the cold airconditioned air escaping from my building. With it installed I do not feel anything escape, which is awesome knowing I'm helping my electric bill, and keeping bugs out. The only complaint I have about this model is the door switch. This unit ships with contact switch that has to physically make contact with your door, or something attached to the door in order to turn off/on the unit. The air curtain I have on my front door, which is an Awoco brand, uses a magnetic switch, which I prefer for several reasons, but mainly because it will endure far more wear before breaking, if ever. All in all, I recommend this for anyone looking for an air curtain. The price is great, you'd have trouble finding something used for a better price than this, I tried, it was more convenient and about the same cost if I purchased one second hand, with the added benefit of getting a brand new piece of equipment.

Works Great!
