Air curtains from Mitsubishi Electric create an invisible barrier of air across doorways, helping commercial spaces keep flies, insects and dust out of air-conditioned environments where doors need to remain open regularly. By projecting a controlled stream of air across the entrance, an air curtain prevents outdoor contaminants from entering while allowing customers and staff to move freely through the doorway. This barrier also supports air conditioning performance by limiting the exchange of indoor and outdoor air, reducing energy waste at busy entry points. Available in various sizes to suit different doorway widths and air volumes for different heights, air curtains in Australia deliver year-round protection for retail, hospitality, healthcare and industrial applications.

Energy performance and comfort

Commercial air curtains enhance air conditioning performance by projecting a controlled sheet of air across doorways to maintain indoor temperature and reduce energy loss. They prevent cool air from escaping during hot Australian summers and retain warmth during winter, reducing the system’s load and lowering running costs. The continuous airflow reduces drafts and temperature fluctuations near entrances, keeping threshold areas comfortable.

Installation flexibility and indoor air quality

Commercial air curtains act as a barrier against outdoor pollutants, including dust, pollen and exhaust fumes that typically enter through busy doorways. By preventing the entry of these airborne contaminants, they help maintain a healthier indoor environment and improve overall air quality in reception areas, cafés and healthcare spaces. An air curtain for home applications provides similar benefits for residential properties with frequently used entrances. Units are available in various widths to suit different doorway sizes, with mounting options that integrate discreetly above entrances. Correct airflow and width selection are essential to maintaining an effective barrier, particularly in locations with high foot traffic or exposure to gusty outdoor conditions. Installation must be carried out by licensed professionals, including a licensed electrician for electrical work.

Insect control and access

A commercial air curtain provides an invisible barrier of air to keep insects out while allowing customers to move freely through open doorways. This is particularly valuable for restaurants and food retail environments, where hygiene standards are paramount and pest control is essential. The airflow volume of the unit determines the effectiveness of insect shut-out, with larger insects requiring stronger air volumes for reliable exclusion. Selecting the right air curtain allows doors to be left open while keeping out flies and other pests, eliminating the need for physical screens that can obstruct sight lines or create barriers to entry. The continuous air stream works without interfering with customer access, maintaining welcoming, accessible entrances that support both trade and hygiene requirements throughout service hours.

FREQUENTLY ASKED QUESTIONS

Air curtains work by utilising a series of fans to blow air either downwards or horizontally. This creates an airflow volume and velocity that forms an invisible barrier between the outside air and the inside air.

Air curtains are typically installed above doors that are open to the outside air, which can lead to temperature control issues. The invisible airstream barrier they create helps prevent the loss of cool air during cooling and heat loss during heating, thus maintaining temperature control and reducing the load on the air conditioning system. Additionally, air curtains contribute to a hygienic environment by keeping insects from entering the premises.

Air curtains can assist with preventing loss of cool air during cooling and heat loss during heating which helps to reduce load on the air conditioning system.

Air curtains, such as the Mitsubishi Electric GK-25/30 Series Air Curtain, feature strong airflow volume and velocity that can effectively prevent the entry of flies and other insects into a premises. This makes them especially beneficial for food service areas like cafes and restaurants where keeping bugs out is crucial.

Top inlet type air curtain models to suit residential and light commercial applications. Airflow rates range from 336 l/s to 483 l/s.

Front inlet type air curtains are used in commercial and industrial applications as they feature stronger airflow rates of 650 l/s to 867 l/s which make them an ideal choice in food production sites and in areas where temperature control and hygiene is critical.

Mitsubishi Electric aircurtains are available in 900 mm and 1180 mm widths models.

Typical applications include supermarkets, cafés, restaurants, healthcare facilities and industrial doorways where busy thoroughfares make temperature control and cleanliness difficult.

Selected top inlet models are suitable for residential foyers and small shops. Speak with an installer to confirm suitability for your doorway width, mounting height and exposure before choosing an air curtain for your home.

For residential and light commercial applications, the GK-25/30 series is a suitable option. For more demanding sites, choose the GK-35 series, which is better suited to larger indoor-to-outdoor temperature differences and locations exposed to stronger outdoor wind.

Front inlet models can be fitted close to the ceiling because they draw air from the front. Top inlet models require a 100 mm clearance above the unit for intake.
