1.3.1 Applications

The comfort air curtain is designed to separate the climates between two rooms. The unit is installed above the doorway, across its full width.

MANUAL INTRODUCTION

The free-hanging model is designed for free, visible installation above the door.

The recessed model is designed for integration into a false ceiling or into a cove, with the inlet opening possibly at some distance from the unit.

The cassette model is designed for installation above a false ceiling, with the inlet opening close to the unit and with easy access to the unit.

1.3.2 Working

The air curtain blows out a warm air stream straight down, thus achieving the following:

• The exchange of air between two rooms due to temperature differences (convection) is stopped.

• The cold air entering across the floor due to draught is heated.
