Rectangular acustic silencers offer a large absorption surface through the acoustic baffles which are incorporated into the system and which are arranged in series. When the air-flow reaches the mouth of the silencer it is divided and channelled, producing a decrease in the sound level, transforming the sonic energy into heat.

Rectangular acustic silencers permit high air-flow levels to be passed through with reduced loss of pressure.

Available in the standard model in galvanised steel, with the acoustic baffles filled with mineral fibres and protected with a fibre glass covering. This product is fully compatible with health regulations and is fire retardant.
