As the only UK company to have assessed Attenuators in a UKAS accredited facility, our products come with a guaranteed performance.

Designing Attenuators for a quiet life

Here at Caice, we take Attenuator development and testing seriously, which is why we are the only company in the UK that had undertaken UKAS accredited Attenuator testing measuring static and dynamic performance fully in accordance with BS EN ISO 7235: 2009. By ensuring testing of our Attenuators, we are able to guarantee noise reduction performance of any unit.

Our noise-reducing attenuators are developed for fan units and other equipment within heating, ventilating and air conditioning, also known as HVAC systems. Generally mounted within the system’s ductwork, they ensure that a specific noise criteria is achieved within the internal or external areas they are installed in.

Attenuators are available in optional internal and external paint finish, as well as being versatile in design, offering an option of vertical or horizontal splitter orientation.

Our comprehensive range offers solutions for rectangular and circular ductwork or products can be specifically designed for installation within apertures and restricted spaces. Attenuator data means we can guarantee the noise reduction performance of any unit.

The range is backed up with attenuator selection software to download.
