The units are rigidly constructed and consist of an outer cylindrical galvanised steel casing, lined internally with no hygroscopic and incombustible sound absorbent material.

The Q-Tech high performance SONEX circular attenuators are the outcome of a testing and development programme in our insertion loss test facility.

Q-Seal attenuators have an impervious seal between the acoustic fill and ambient air

The units are rigidly constructed and consist of a galvanised sheet metal casing containing a series of centre and side splitters.

The Q-Tech range of Cross-Talk attenuators has been designed to provide a low resistance to air flow whilst maintaining a high degree of acoustic attenuation.

In modern buildings there is an increasing need to provide large air flow openings for plant and equipment, whilst minimising noise impact effects on the environment.

The use of acoustic louvres or control of plant noise to atmosphere is now a widely accepted practice.

Silencer overall length includes a 300mm long plenum section which should be fitted to the fan flange when silencers/fans are coupled.

The Aero acoustic louvre with its aerofoil shape blade design creates less air flow resistance to maximize air flow into stand-alone plant rooms, return air intakes and generator rooms.
