Wide range of sizes from 100Ø upwards to suit standard duct and fan sizes.

• Available in two series – with & without central pod - for maximising performance.

• Standard length increments from 1 diameter to 4 diameters, or to suit specific applications.

Standard construction is from galvanised steel, with special construction variants available in aluminium or stainless steel finish for harsh environments, or with impervious membranes for moisture laden environments.

For applications where increased performance is required under demanding conditions, NAP can offer a customised solution with guaranteed acoustic and aerodynamic performance.
