While we manufacture silencers and ductings up to approximately 4000mm in diameter we also supply very small silencers. And not only for our standard range of silencers as you find them on our website. On the picture you see some of the 30 very compact and very custom DN80 blow-off silencers as we have supplied mid February of this year. Although they are very small in size, they a very large in performance . Giving a bit more silence on the plants of one of the leading oil and gas companies in the world. Contact us here if your blow-off noise is driving you crazy!
