Acoustic louvres reduce noise pollution from plant rooms and air handling systems, whilst providing essential intake or exhaust airflow to the equipment behind.
Designed to be used in any type of building with the requirement to reduce noise from air intake/exhaust openings, from power stations and chemical treatment plants to commercial office buildings or manufacturing plants.

Pressure Drop
Pressure drop is defined as the pressure differential from one side of a louvre to the opposite side, often expressed in Pascals (Pa). Louvre pressure drop occurs when frictional forces, caused by the resistance to flow, act on air moving through a louvre.
Increased louvre pressure drop can prevent equipment inside the ventilated area drawing sufficient air through the louvre, resulting in overheating, as the equipment has to work harder to draw the air through.
Face Velocity
Face velocity is the speed at which the air will be moving through the louvre
