Windshield fan (Air Curtain) also known as wind blocking fan, wind cutting fan is a common line of fans installed at the doors of commercial centers, warehouses, etc., which must be opened regularly.

Windshield fans help prevent cold air loss and prevent the ingress of dirt and insects from outside to keep the space inside always clean.

Principle of operation

Looks like an air conditioner, but the windscreen fan has a different structure and operating principle. Inside the fan is a squirrel cage centrifugal fan, similar to an air conditioner, but with a larger blowing capacity, the outlet air flow has a much higher speed than the air conditioner.

With a structure of one air inlet and one door used to blow air, when operating, it can create an invisible air curtain separating two different temperature environments.

• Prevent the loss of cold air from the air conditioner
• Prevent the entry of insects
• Prevents odors and dirt from outside
• Create comfort for people when traveling through the door
• Space saving by not needing to install doors
