What is an industrial air curtain? An industrial air curtain is a robust and heavy-duty air curtain designed for larger commercial and industrial openings such as warehouse doors, factory entrances, loading bays, distribution centres, workshops, aircraft hangars, cold stores and logistics facilities. Industrial air curtains are designed for larger door heights, wider openings, higher air flow, and more demanding working conditions, unlike smaller commercial air curtains used over shop or office doors.

An industrial air curtain’s main purpose is to create a powerful stream of air across an open doorway. This air flow acts as an invisible buffer between the inside and outside of the building. It helps to reduce the movement of air through the opening, which can help to reduce heat loss, cold draughts, dust, fumes, insects, vehicle emissions and airborne contaminants entering the building.

Industrial buildings typically have large doors which are frequently opened for forklifts, deliveries, staff movement or vehicle access. Every time these doors are opened, warm air from inside can escape and cold air from outside can enter. This can put an additional load on the heating system in winter and make working areas uncomfortable. An industrial air curtain mitigates this problem by reducing uncontrolled air exchange while allowing access through the open doorway.

Industrial air curtains can be either ambient or heated. An ambient industrial air curtain offers an unheated barrier of air. It is often employed where separation is the main requirement, such as in cold stores, chilled areas, warehouses and process areas. Heated industrial air curtains do more than just separate air; they add heat. This type of curtain works particularly well for loading bays, factory doors and industrial entrances where comfort and heat retention are an issue.

Heated industrial air curtains can be electric, LPHW, or gas-fired air curtains according to the application. LPHW models are linked to a low-pressure hot water heating system, whereas gas-fired air curtains can be used where very high heat outputs are required and a supply of gas is available. The optimum solution depends on the type of building, services available, door size, heating demand and operating pattern. They can also be supplied in ambient, unheated versions.

The industrial air curtain offers the key benefit of helping to improve working conditions close to large doors. In winter, staff working near loading bays or warehouse entrances are often exposed to cold draughts. Correctly chosen, an air curtain can increase the comfort of these spaces and reduce complaints about cold air coming into the building.

But picking the right one is really important. The industrial air curtain must be appropriate for the door height, door width, mounting position, external wind load, internal building pressure and frequency of door usage. If the unit is too small, installed too high or in the wrong place, the air stream may not reach the floor properly, and performance will be compromised.

Basically, an industrial air curtain is a powerful doorway air barrier intended for large commercial and industrial openings. It reduces drafts, heat loss, dust entry and temperature fluctuations and allows doors to remain open for access. Properly specified and installed, it can enhance comfort, support energy efficiency and help protect the working environment.
