P.N. Erichsen is offering a wide range of standard silencers from Universal, such as:

ADS serie

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 serie

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 serie

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 serie

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 & SPA serie

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.

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
