Air Curtains Frequently Asked Questions

Our air curtains FAQ webpage is a useful guide that is designed to answer the most frequently asked questions on air curtains: what they are, how they work, where they are used and what benefits they can provide. Shops, offices, warehouses, factories, restaurants, hotels, commercial buildings and industrial premises often use air curtains above doorways and entrances.

An air curtain is a controlled stream of air across an open doorway. This air stream creates an invisible barrier between the inside and outside of a building. This is to reduce the amount of warm air that escapes in winter, to cut down on cold draughts and help keep the indoor temperature more comfortable. Air curtains can also help prevent dust, fumes, insects and outdoor air from entering into an area.

Different types of air curtains available in the market include electrically heated air curtains, water-heated air curtains, ambient air curtains, commercial air curtains, industrial air curtains and recessed air curtains. The correct type depends on the size of the doorway, the height of the mounting, the use of the building, the heating requirement and the frequency of door openings.

The air curtains FAQ section is aimed at providing clear and simple answers to important questions such as how air curtains work, where to install air curtains, do air curtains save energy? What size air curtain do I need? ; heated air curtains vs ambient air curtains; noise levels; controls; maintenance; and is an air curtain suitable for my building?
