What are air curtains?
An electric air curtain is a fan unit above a doorway that blows a stream of air downwards. It separates indoor and outdoor air, keeping out dust, insects and heat while the door stays open. A PVC strip curtain does a similar job with overlapping plastic strips.
Shops, restaurants, cold rooms and factories use them to save energy and keep areas clean.
