Description
The largest CarboAir 60 unit — 315mm diameter, 1200mm long, rated at 4500m³/hr — is a commercial-scale carbon filter for operations where airflow volume and sustained odour control both need to be at the top end of what’s available. The 60mm activated carbon bed depth provides long contact time and high adsorption capacity, meaning the filter stays effective at high face velocities and across extended service periods. At this physical size and weight, structural mounting support is essential — do not rely on fan housing alone to carry the filter at this scale. Match to an appropriately rated fan and correctly sized ducting throughout the system for the filter to perform to its rated capacity.
Sizing extraction correctly starts with matching fan capacity, filter capacity and ducting diameter as a single system rather than choosing each component in isolation — a filter rated for 4500m³/hr paired with an undersized fan or narrow ducting won’t reach its rated performance, since the whole system is limited by its most restrictive point. Ducting for this filter should be sized appropriately to avoid unnecessary pressure drop over the run length, and any bends in the route should be kept to a minimum, since each bend adds resistance a fan has to work harder to overcome. Position the filter as close to the extraction point as practical — mounting it directly to the fan or with a short connecting duct reduces the length of unfiltered ducting between the canopy and the filter, minimising any odour escape from joins along the way. Activated carbon has a finite service life that depends on usage intensity and ambient odour load rather than a fixed calendar interval, so monitor for reduced odour control effectiveness over time as an indicator the carbon bed needs replacing rather than working to a strict schedule.
