Nominal insulation thicknesses are 50 or 100 or 150 mm.

Attenuation material is Acutec® polyester. The PVDP's are made from galvanizes steel sheet and an inner tube made of sheet steel with small openings to be able to withstand mechanical cleaning and at the same time not interfere with the insertion loss. Silencer can be cleaned by rotating nylon brushes, vacuum cleaner or damp cloth.

Tested according to ISO 7235 standard.

Fulfils tightness class C.

Special materials, sizes and flanges on request. Please contact Lindab sales.
