Diffusers for displacement air distribution give quiet installations with both good air comfort and high ventilation efficiency. The system also permits economical and effective air cooling. Fläkt Woods has a large range of displacement air terminal devices with different forms and capacities.
Floormaster terminal devices are equipped with an air distribution system consisting of a roll-shaped perforated distribution plate with an attached honeycomb sheet in black polycarbonate. This component combination permits uniformly horizontal air distribution through the front panel with a short near zone and a very low noise level.

Semi-circular

Floormaster DVHA is a semi-cylindrical supply air terminal device developed for displacement ventilation. DVHA is designed for positioning on a wall or floor, with connection to circular ducts.

Quarter-circular

Floormaster DVQA is a quater-cylindrical supply air terminal device developed for displacement ventilation. DVQA is designed for positioning in a corner, with connection to circular ducts.

Circular

	Floormaster DVRA is a cylindrical supply air terminal device developed for displacement ventilation. DVRA is designed for positioning on the floor, with connection to circular ducts.
	Circular displacement diffusers WO-S (standing) and WO-Z (hanging) are suitable for industrial rooms and where is the necessity to supply a large quantity of air flow directly into to the working area.

Rectangular

	Floormaster DVPA is a flat supply air terminal device developed for displacement ventilation. DVPA is designed for positioning on a wall, or on the floor against a wall, with connection to rectangular ducts.
