Dürr Universal silencers
Dürr Universal’s products comply with internationally recognized standards for processes (ISO 9001:2008) and with their more than 50 years experience in designing and producing silencers we are able to offer the optimal solutions to our customers.
P.N. Erichsen is offering a wide range of standard silencers from Universal, such as:
ADS series
An absorbative silencer with a very low back pressure recommended for the silencing of internal combustion engine exhaust and air vacuum discharges.
Available in two attenuation ratings: 25dB / 35dB
OPS series
Reactive silencers, recommended for industrial and marine applications where low frequency noise dominates.
The design consists of a series of expansion chambers having interconnecting tubes.
The OPS range is available in two attenuation ratings: 25dB / 30dB.
BSE series
BSE combination silencers are highly recommended when it comes to optimum silencing applications.
The silencer unit is designed with a reactive chamber and an absorptive chamber to treat low and high frequencies.
The BSE range is available in three attenuation ratings: 25dB, 35dB and 45dB.
DSA & DDA series
Combinations silencers recommended for small and medium size petrol engines. They employ a twin or triple chamber designe combatting low and high frequencies in separate reactive and absorptive chambers.
OPA series
The OPA range of spark arrestor silencers are recommended for industrial and marine applications where low frequency noise dominates.
They are available in two attenuation ratings: 25dB / 30dB.
SPA series
SPA spark arrestors are recommended for use in hazardous areas where fire precautions prevail. The unique design allows dangerous sparks to be removed from the exhaust gas as well as providing up to 20dB attenuation. The hot carbon particles are trapped safely within the arrestor dustbox for removal later.
EES & BSA serie
The EES (small bore) and BSA series are spark arresting combination silencers designed for industrial and marine applications where low noise frequencies dominate
