Air curtains

Air curtains can be installed on door openings for facilities including food processing, cold storage, logistics, automobile parts, machine manufacturing and more.
Designed as a solution to improve energy savings and cleanliness control by preventing heat leakage and insect intrusion.

Insect repellent

Bugshutter - insect repellent air curtain

Bugshutter is an insect-repelling air curtain that shuts out insects and dust and keeps them from entering places such as food processing factories, distribution centers, and pharmaceutical processing facilities through building openings. Flying insects (houseflies, etc.) and those entering through food processing plant pharmaceutical manufacture hygiene problems such as bacteria being brought into the facility and insects getting mixed in with products can be safeguarded by preventing insects from entering the processing plant. More better protection from insects can be expected when used in combination with sheet shutter.
Additionally, it prevents heat from entering and escaping at the same time, so it can also serve as an energy-saving device.
・An air curtain solves the root problem by sucking in and capturing insects.
・The double air wall blocks insect intrusion.
・Implement more precise countermeasures by monitoring trapped insects.
・Gatepost-type design enables easy installation, along with easy insect removal and maintenance.

Double air walls prevent insects from entering


  • Good for widths up to 3,200mm (10.5ft)
  • Operating environment: 50 to -10℃ (122 to 14℉), relative humidity: 90% or less (even if the requirements on the left are met, there must be no icing or frosting)


  • Food processing factory
  • Meat handling center
  • Distribution center
  • Central kitchen
  • Pharmaceutical factory
  • Film production factory
  • Resin processing factory

Heat shield

Thermoshutter - heat shield air curtain


Thermoshutter is an air curtain that prevents air from entering and exiting a facility through openings where there are different temperatures on each side. An average thermal blocking efficiency rate of 75% (Mayekawa study) can be achieved.
This air curtain prevents warm air from flowing in and cold air from flowing out through openings in cold storage facilities where activities such as food production and distribution are taking place, solving problems such as rising storage temperatures and increased costs for cooling equipment.
・Stable storage temperature ensures product quality.
・Less condensation and frost in a cold storage decreases the defrost frequency.
・Prevention of heat loss reduces power consumption.

Optimal shielding of incoming warm air and outgoing cold air


  • Good for widths up to 3,000mm (9.8ft)
  • Operating environment: 45 to -10℃ (113 to 14℉), relative humidity: 90% or less (even if the requirements on the left are met, there must be no icing or frosting)


  • Cold storages
  • Frozen storages
  • Anterooms(dock shelter, air shelter)

Heat shield

Thermoshutter ARX - heat shield air curtain for higher temperature

Thermoshutter ARX

Thermoshutter ARX is an air curtain unit which blocks heat by generating a strong air circulation at the furnace and subsequent opening.
A stable temperature can be achieved, which contributes to reducing heat load and energy consumption in the furnace area.
Prevention of heat leakage can also provide a safer working environment.
Blocks heat as high as 200℃ (392℉). Using 2 units in 1 area can enhance the maximum blocking efficiency up to 85%. (Based on internal study)
Ideal for industries which require heating and drying furnaces
・Achieves stable furnace temperature by preventing heat leakage
・Producing a stable furnace temperature means reduced heat load and energy consumption
・Prevention of heat leakage can provide a safer working environment
・Blocks heat as high as 200℃ (392℉)

Heat shield efficiency can be improved by installing two units.


  • Applicable to widths up to 1500mm (4.9ft)
  • Furnace temperature: 200℃ (392℉) or less
  • Operating environment: 40℃ (104℉) or less, humidity less than 90%
  • Explosion-proof structure: Not applicable


  • Heating furnaces
  • Drying furnaces
  • Paint booths
  • Annealing chambers
  • Aging ovens
