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.
