NAP Circular silencers are used wherever it is necessary to control the passage of noise along an air path.

In industrial applications, specially designed and constructed circular silencers control noise from fans and blowers, cooling towers, dust extraction systems and similar air or gas handling equipment such as compressors and turbines.


A standard range comprising Types CS (without pod) and CSP (with pod) is offered from 305mm to 2415mm diameter, and each range is available in two lengths.

For CS-1D and CSP-1D the length of silencers is equal to one diameter, and for CS-2D and CSP-2D, the length is equal to two diameters.
