Description
The column diffuser PPV-2 allows the supply of large amounts of air and is therefore intended for ventilating large spaces such as industrial halls, large stores, sports halls, etc.
The closed damper during cooling allows the supplied air to be fed into the room horizontally, high above the living area and then slowly descend. This creates a pool of fresh air over the entire floor area.
In heating mode, the damper is open. The air is discharged vertically downwards.
