HEMSCO Air Curtains are extremely beneficial for commercial and industrial facilities looking to streamline workflow, reduce costs, keep insects out, control temperatures and protect employees and goods from adverse conditions such as noise, heat, cold, humidity, dust and drafts.
HEMSCO Air Curtain or Air Door utilize a unique compression chamber to create a "Coanda Effect" that collects air emitted from the blowers and create a concentrated air stream that flows from the chamber and covers the entire doorway with a solid shield of air. This airstream reduces unwanted/unconditioned air infiltration while enabling doorways to be left open so that people, equipment and inventory can pass freely.
Air Curtains / Air Doors from HEMSCO create an invisible barrier of high velocity air to separate and manage environments, keeping conditioned air within the workspace, and the same time keeping unconditioned air, pests and pollutants out. HEMSCO Air Curtains can be mounted above a doorway opening, just above the header. Ambient air is drawn through the front intake grill (A)* and into the fan baskets (B). The blower wheel (C), forces the air into HEMSCO's state-of-the-art air chambers, compressing the air (D) and forcing if downward through the discharge nozzle (E). An invisible "air shield" is created that serves as the barrier preventing conditioned air from leaving the building and blocking outside air from entering, even when there is no primary door in place.
Usages of Air Curtain
Flying Insect Control: The air shield is nearly impenetrable for flying insects; keeping them at bay, along with bugs, dust and airborne contaminants are also kept from entering.
Cold Storage: For cooler doors, HEMSCO Air Doors/Air Curtains offer a safe, effective and affordable solution that keeps conditioned air in place but enables workers to pass freely between regular work areas and coolers.
Interior: Air Door are often used at interior at doorways of industrial and commercial facilities to separate environments and to provide an invisible barrier for protection against drafts, dust, dirt, odours and fumes.
Exterior: Air Doors are not designed for security purposes. They are secondary doors that allow unrestricted access to the outside while conserving energy. Also, special types of Air Doors protect against flying insects dust and dirt.

Additional Features of Air Curtains
Air Doors/ Air Curtain are capable of blocking the flying insects from coming through open doorways.
It can be used in all seasons. When summer heat and humidity become a problem, an air curtain will create an invisible shield that will hold conditioned air in and heat out.
