Sira silencers stand as an optimal solution when the goal is to efficently control noise emissions coming from chimneys, waste pipes, ventilation bays. According to noise characteristics, the suitable device will be selected into absorbing or double-stage silencers range.

These devices will be used to achieve noise dampening against spreading-through gaseous fluids sonic waves. Such waves will feature 20 m/s maximum passing-through speed. Absorbing silencers are typically installed over ventilation systems, inlet and outlet ventilator holes, conditioning systems. Absorbing silencers are composed by shells containing noise absorbing septums (batteries). Both shells and batteries may be cylindrical or parallelepiped. Solid partitions The rate of solid/empty partitions defines silencer’s capacity to operate in a specific spectrometry area. Moreover, the same rate will be designed to optimize load losses according to available head pressure before silencer.
