Intake & Stack Silencers

Innovation and reliability for your filtration, ventilation and air treatment needs with noise reduction. With a success history of over 60 years in engine and boiler unit installations all over the world, STOPSON Italiana designs and manufactures air filters, silenced intake ducts, ventilation systems, by-pass chimneys and exhaust ducts with septa silencers, ensuring superior performance and significant reduction in noise emissions. .

Air Filtration Systems and Duct Silencers

Air filters, silenced intake ducts, ventilation systems, by-pass chimneys and exhaust ducts with septa silencers: thanks to the experience gained in over 60 years of installation of engine and boiler units all over the world, STOPSON Italiana is able to provide complete and effective solutions to optimize the performance of systems and significantly reduce noise emissions.

Inlet Air Filtration Duct Silencers

A well-designed inlet air filtration system is essential to ensure the proper operation and long life of gas turbines and diesel/gas engines. The ingress of contaminated air can compromise engine performance by causing fouling, erosion and corrosion, particularly in turbine packages.

STOPSON designs tailor-made air filtration systems, optimized for each application. Once the most suitable filtration system has been selected, we also provide a comprehensive range of duct silencers and filter systems, designed to minimise noise generated by the incoming airflow before reaching the compressor.

The silencers are made with a septa configuration (splitter), designed to offer:

  • Minimal pressure drop, maximizing the air flow to the compression chamber
  • High acoustic efficiency
  • Easy installation even in existing systems
  • Modularity for systems with an output of up to 250 MW and even more

Possibility of supplying self-supporting filter packages, including pulse-jet filters for dust removal at the turbine inlet

Silencers for by-pass chimneys and main chimneys

Noise pollution control is a priority for many organizations. It is essential that noise from air exhaust openings implements the necessary noise control measures so as to ensure that the installation meets the relevant noise criterion.

STOPSON is an expert in noise control engineering and is one of the most important manufacturers for engine and boiler silencers. We provide competitive solutions to mitigate the noise generated by single-cycle and combined-cycle plants used for electricity generation or cogeneration plants, leveraging our long-standing experience from many installations around the world by offering standard or customized solutions to suit gas turbines with powers ranging from 2MW to 250MW.

The silencers of the exhaust duct are of the splitter type, made of absorbent liners inserted in perforated stainless steel sheets and fixed to the structure of the duct by means of appropriate support systems. We can offer only the filter element of the splitter silencer or the entire exhaust duct, according to customer and project requirements.

Septa type silencers offered by STOPSON
