Circular Inline Silencers - 0.6M long - SLU-600

£ 58.40 (excl. VAT)

£ 70.08 (inc. VAT)

Inline Circular Attenuators in standard diameters from 100mm to 400mm diameter. Attenuators are available in standard 300mm, 600mm, 900mm and 1200mm lengths.
This version is 600mm long
The longer the unit, the more effective it is.

Attenuator construction for this range comprises a pre-galvanised sheet steel spiral wound outer casing, manufactured in accordance with HVCA DW144 specification, with circular spigoted end caps. The inner bore is manufactured from pre-galvanised and perforated spiral wound steel tube, retaining a 50mm thick scrim faced 45 kg/cu.m acoustic media.

This range of circular attenuators offer minimal resistance to airflow and can be used in a variety of noise control applications:-
• Small fan system attenuation
• Cross-talk attenuation
• System noise regeneration attenuation
• System terminal unit attenuation

I have a loft mount extractor fan which was very noisy. I installed one of these silencers (600mm)and it made a massive difference so much quieter highly recommend !!!

Look good, works well, except the shaft of the lanellae cuts...
