The stated differential pressures for circular silencers correspond to the values for smooth pipes. Deviations, if any, are of no practical relevance.
For ductwork calculation, if the length of a circular silencer is included in the total length of the ductwork, no extra length must be added.

Plastic circular silencers for use in extract air systems subject to aggressive media; they reduce the air-regenerated noise in plastic ducts (absorption principle).
Insertion loss measured according to ISO 7235.
Absorption material is mineral wool with RAL quality mark RAL-GZ 388.
Spigot, suitable for ducts according to DIN 8077.
Casing air leakage to EN 15727, class D.

All sound power levels are based on 1 pW.
All values were measured in a TROX lab and to EN ISO 7235. Intermediate values may be achieved by interpolation.
Lab measurements exceeding 50 dB are indicated as 50 dB, in line with common practice.
