Fantech Air Screen Keeps the Inside In and the Outside Out Open doors and entryways create drafts, increase energy costs and introduce pollutants. Installing a Fantech Air Screen over the opening adds a "barrier" in the opening. Heated units improve the comfort by adding heat and drying up the entrance area. The additional heat also serves as buffer on very cold days. Under optimum conditions, the Fantech Air Screen can reduce heat loss by up to 80%, efficiently maintaining a comfortable air temperature and shielding against insects, dust and other contaminants Why Fantech Air Screen Makes a Great Entrance Fantech Air Screens are quiet enough not to disturb occupants, allowing efficient continuous operation in all installations. The seasons in which doors can be left open are extended with air screens. Customers are attracted to shops with open doors. Heated units give a feeling of welcoming warmth as the customer enters the space, plus the entrance remains dry. The reduction in drafts through the openings increases the energy efficiency of the building. The air velocity is optimized to provide an effective barrier against insects, pollen and dust, while not disturbing occupants. Fantech Air Screens are elegantly styled and installation is simple. Superior German motor technology ensures reliable operation and long life span. AS 4000 and AS 6000 Series... Quiet comfort for full-height doorways Fantech Air Screens are mounted internally over entrances to reduce draft and heat loss while creating a barrier against dust, insects and pollution. A thin "screen" of air is pushed along the opening by fans built into the unit. Heating elements increase the temperature of the air stream. Unheated models are available for air conditioned climates. The Air Screens can be controlled manually or wired to thermostats and/or door switches for automated operation.   Air Speed/Distance The diagram to the right shows the air speed for the AS 4000 and AS 6000 measured at different distances from the center of the outlet gap.   Construction A cross-flow fan and optional heating elements are mounted in a compact, durable frame made of powder-coated sheet metal. Fantech's European design and technology provide the optimum combination of low noise level, airflow with minimal turbulence and a constant indoor air temperature. Safety Equipment Thermal protection is placed in the airflow on the outlet side.An easily accessible reset button is located behind the front panel. Mounting The fantech Air Screen is designed for horizontal, fixed installation. The low height of the appliance and the front inlet allow mounting close to the ceiling. This saves space and allows the air screen to be used in places where there is minimal room between the door and the ceiling. Air screens can be flush-mounted in the lower ceiling or suspended by wires or threaded rods. Operation Fan speed and heat have high and low settings and are regulated from a built-in control. For your convenience, the control panel can be removed from the unit and installed remotely. If installed, the optional door switch shall be wired for the fan to go from low to high speed when the door is opened. When installed in small spaces an optional two-stage thermostat is recommended.
