Air Curtains

The air curtain is a device installed above doorways, creating a flow of high speed air over an entrance way. The invisible air wall creates separation between the indoor air and the outside air, allowing companies to maintain the indoor climate during door openings and closures, which helps to control temperature, energy consumption, dust, insects, fumes, and smells. Some other names for air curtains are: air doors, air shields or air screens & air cutter machines, and they are used by many industries, from restaurants and retailers to warehouses, food factories, airports, and metros.

What Problems Does an Air Curtain Solve?

Air curtains are designed for use in places where the frequency of door openings is too high, such as corporate buildings entrances, for these kind of prolonged periods throughout working hours. The high speed air jet solves the issues arising from a door left open.

• Loss of cooled or heated air through the open doorway
• Dust, insects, odors, smoke, and exhaust gases entering the area from outdoors
• Discomfort experienced by the workers and customers due to hot or cold air flow
• Higher energy bills and inefficiency in cooling/heating system operation
• Risk of contamination in food establishments, hospitals, etc.
• Entry of insects and birds into food preparation rooms, storage units, manufacturing facilities, etc.
  

An air curtain is thus well suited to establishments needing access via open doors but not desiring the losses associated with it.

• Determine the appropriate air flow rate and velocity according to the height of the door
• Consider suitable body construction using ABS, metal or stainless steel based on use
• Consider motor strength, sound and energy performance with regard to duty cycles
• Automation options like sensor activation, manual door switch, and remote operation
• Availability of warranty, AMC services and pan India service support
