Donaldson provides with innovative silencing solutions to meet the total system designs economics in most challenging site noise limit conditions and airflow resistance requirements. The machinery long-term protection remains paramount as well as its operating cost.
This requires specific expert knowledge in this particular turbo-machinery protection field. Donaldson is your total air intake system partner.

Air Inlet Silencers
The noise emissions are facing constantly stringer environmental limits. They are expressed not only in overall noise dB(A) at a given distance but in terms of overall noise energy power and even sometimes within maximum frequency band perceptions.


Intermittent noise reduction
Intermittent noise pulses of self-cleaning filter systems must be addressed but also the anti-icing and/or NOx systems and other air intake accessories have to be taken into account for calculating the overall noise performances of the air intake.



Expertise towards innovative solutions
The machinery intake noise keeps increasing and must be abated in ever smaller ducting sizes. The side wall flanking noises must also be controlled.
